===========================================
Configure access and security for instances
===========================================
Before you launch an instance, you should add security group rules to
enable users to ping and use SSH to connect to the instance. Security
groups are sets of IP filter rules that define networking access and are
applied to all instances within a project. To do so, you either add
rules to the default security group :ref:`security_groups_add_rule`
or add a new security group with rules.
Key pairs are SSH credentials that are injected into an instance when it
is launched. To use key pair injection, the image that the instance is
based on must contain the ``cloud-init`` package. Each project should
have at least one key pair. For more information, see the section
:ref:`keypair_add`.
If you have generated a key pair with an external tool, you can import
it into OpenStack. The key pair can be used for multiple instances that
belong to a project. For more information, see the section
:ref:`dashboard_import_keypair`.
.. note::
A key pair belongs to an individual user, not to a project.
To share a key pair across multiple users, each user
needs to import that key pair.
When an instance is created in OpenStack, it is automatically assigned a
fixed IP address in the network to which the instance is assigned. This
IP address is permanently associated with the instance until the
instance is terminated. However, in addition to the fixed IP address, a
floating IP address can also be attached to an instance. Unlike fixed IP
addresses, floating IP addresses are able to have their associations
modified at any time, regardless of the state of the instances involved.
.. _security_groups_add_rule:
Add a rule to the default security group
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This procedure enables SSH and ICMP (ping) access to instances. The
rules apply to all instances within a given project, and should be set
for every project unless there is a reason to prohibit SSH or ICMP
access to the instances.
This procedure can be adjusted as necessary to add additional security
group rules to a project, if your cloud requires them.
.. note::
When adding a rule, you must specify the protocol used with the
destination port or source port.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Access & Security` category. The
:guilabel:`Security Groups` tab shows the security groups that are
available for this project.
#. Select the default security group and click :guilabel:`Manage Rules`.
#. To allow SSH access, click :guilabel:`Add Rule`.
#. In the :guilabel:`Add Rule` dialog box, enter the following values:
* **Rule**: ``SSH``
* **Remote**: ``CIDR``
* **CIDR**: ``0.0.0.0/0``
.. note::
To accept requests from a particular range of IP
addresses, specify the IP address block in the
:guilabel:`CIDR` box.
#. Click :guilabel:`Add`.
Instances will now have SSH port 22 open for requests from any IP
address.
#. To add an ICMP rule, click :guilabel:`Add Rule`.
#. In the :guilabel:`Add Rule` dialog box, enter the following values:
* **Rule**: ``All ICMP``
* **Direction**: ``Ingress``
* **Remote**: ``CIDR``
* **CIDR**: ``0.0.0.0/0``
#. Click :guilabel:`Add`.
Instances will now accept all incoming ICMP packets.
.. _keypair_add:
Add a key pair
~~~~~~~~~~~~~~
Create at least one key pair for each project.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Access & Security` category.
#. Click the :guilabel:`Key Pairs` tab, which shows the key pairs that
are available for this project.
#. Click :guilabel:`Create Key Pair`.
#. In the :guilabel:`Create Key Pair` dialog box, enter a name for your
key pair, and click :guilabel:`Create Key Pair`.
#. Respond to the prompt to download the key pair.
.. _dashboard_import_keypair:
Import a key pair
~~~~~~~~~~~~~~~~~
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Access & Security` category.
#. Click the :guilabel:`Key Pairs` tab, which shows the key pairs that
are available for this project.
#. Click :guilabel:`Import Key Pair`.
#. In the :guilabel:`Import Key Pair` dialog box, enter the name of your
key pair, copy the public key into the :guilabel:`Public Key` box,
and then click :guilabel:`Import Key Pair`.
#. Save the ``*.pem`` file locally.
#. To change its permissions so that only you can read and write to the
file, run the following command:
.. code-block:: console
$ chmod 0600 yourPrivateKey.pem
.. note::
If you are using the Dashboard from a Windows computer, use PuTTYgen
to load the ``*.pem`` file and convert and save it as ``*.ppk``. For
more information see the `WinSCP web page for
PuTTYgen <http://winscp.net/eng/docs/ui_puttygen>`__.
#. To make the key pair known to SSH, run the :command:`ssh-add` command.
.. code-block:: console
$ ssh-add yourPrivateKey.pem
The Compute database registers the public key of the key pair.
The Dashboard lists the key pair on the :guilabel:`Access & Security` tab.
Allocate a floating IP address to an instance
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When an instance is created in OpenStack, it is automatically assigned a
fixed IP address in the network to which the instance is assigned. This
IP address is permanently associated with the instance until the
instance is terminated.
However, in addition to the fixed IP address, a floating IP address can
also be attached to an instance. Unlike fixed IP addresses, floating IP
addresses can have their associations modified at any time, regardless
of the state of the instances involved. This procedure details the
reservation of a floating IP address from an existing pool of addresses
and the association of that address with a specific instance.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Access & Security` category.
#. Click the :guilabel:`Floating IPs` tab, which shows the floating IP
addresses allocated to instances.
#. Click :guilabel:`Allocate IP To Project`.
#. Choose the pool from which to pick the IP address.
#. Click :guilabel:`Allocate IP`.
#. In the :guilabel:`Floating IPs` list, click :guilabel:`Associate`.
#. In the :guilabel:`Manage Floating IP Associations` dialog box,
choose the following options:
- The :guilabel:`IP Address` field is filled automatically,
but you can add a new IP address by clicking the
:guilabel:`+` button.
- In the :guilabel:`Port to be associated` field, select a port
from the list.
The list shows all the instances with their fixed IP addresses.
#. Click :guilabel:`Associate`.
.. note::
To disassociate an IP address from an instance, click the
:guilabel:`Disassociate` button.
To release the floating IP address back into the floating IP pool, click
the :guilabel:`Release Floating IP` option in the :guilabel:`Actions` column.

==========================
Create and manage networks
==========================
The OpenStack Networking service provides a scalable system for managing
the network connectivity within an OpenStack cloud deployment. It can
easily and quickly react to changing network needs (for example,
creating and assigning new IP addresses).
Networking in OpenStack is complex. This section provides the basic
instructions for creating a network and a router. For detailed
information about managing networks, refer to the `OpenStack
Administrator
Guide <https://docs.openstack.org/admin-guide/networking.html>`__.

===========================
Create and manage databases
===========================
The Database service provides scalable and reliable cloud provisioning
functionality for both relational and non-relational database engines.
Users can quickly and easily use database features without the burden of
handling complex administrative tasks.
.. _dashboard_create_db_instance:
Create a database instance
~~~~~~~~~~~~~~~~~~~~~~~~~~
**Prerequisites.** Before you create a database instance, you need to
configure a default datastore and make sure you have an appropriate
flavor for the type of database instance you want.
#. **Configure a default datastore.**
Because the dashboard does not let you choose a specific datastore to
use with an instance, you need to configure a default datastore. The
dashboard then uses the default datastore to create the instance.
#. Add the following line to ``/etc/trove/trove.conf``:
.. code-block:: console
default_datastore = DATASTORE_NAME
Replace ``DATASTORE_NAME`` with the name that the administrative
user set when issuing the :command:`trove-manage` command to create the
datastore. You can use the trove :command:`datastore-list` command to
display the datastores that are available in your environment.
For example, if your MySQL data store name is set to ``mysql``,
your entry would look like this:
.. code-block:: console
default_datastore = mysql
#. Restart Database services on the controller node:
.. code-block:: console
# service trove-api restart
# service trove-taskmanager restart
# service trove-conductor restart
#. **Verify flavor.**
Make sure an appropriate flavor exists for the type of
database instance you want.
**Create database instance.** Once you have configured a default
datastore and verified that you have an appropriate flavor, you can
create a database instance.
#. Log in to the dashboard.
#. From the CURRENT PROJECT on the :guilabel:`Project` tab, select the
appropriate project.
#. On the :guilabel:`Project` tab, open the :guilabel:`Database` tab and
click :guilabel:`Instances` category. This lists the instances that
already exist in your environment.
#. Click :guilabel:`Launch Instance`.
#. In the :guilabel:`Launch Database` dialog box, specify the following values.
Details
:guilabel:`Database Name`: Specify a name for the database instance.
:guilabel:`Flavor`: Select an appropriate flavor for the instance.
:guilabel:`Volume Size`: Select a volume size. Volume size is expressed in
GB.
:guilabel:`Initialize Databases`: Initial Database
Optionally provide a comma separated list of databases to create, for
example:
``database1``, ``database2``, ``database3``
:guilabel:`Initial Admin User`: Create an initial admin user. This user will
have access to all the databases you create.
:guilabel:`Password`: Specify a password associated with the initial admin
user you just named.
:guilabel:`Host`: Optionally, allow the user to connect only from this host.
If you do not specify a host, this user will be allowed to connect from
anywhere.
#. Click the :guilabel:`Launch` button. The new database instance appears in
the databases list.
Backup and restore a database
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can use Database services to backup a database and store the backup
artifact in the Object Storage service. Later on, if the original
database is damaged, you can use the backup artifact to restore the
database. The restore process creates a database instance.
This example shows you how to back up and restore a MySQL database.
To backup the database instance
-------------------------------
#. Log in to the dashboard.
#. From the CURRENT PROJECT on the :guilabel:`Project` tab, select the
appropriate project.
#. On the :guilabel:`Project` tab, open the :guilabel:`Database` tab and
click :guilabel:`Instances` category. This displays the existing
instances in your system.
#. Click :guilabel:`Create Backup`.
#. In the :guilabel:`Backup Database` dialog box, specify the following
values:
Name
Specify a name for the backup.
Database Instance
Select the instance you want to back up.
#. Click :guilabel:`Backup`. The new backup appears in the backup list.
To restore a database instance
------------------------------
Now assume that your original database instance is damaged and you
need to restore it. You do the restore by using your backup to create
a new database instance.
#. Log in to the dashboard.
#. From the CURRENT PROJECT on the :guilabel:`Project` tab, select the
appropriate project.
#. On the :guilabel:`Project` tab, open the :guilabel:`Database` tab and
click :guilabel:`Backups` category. This lists the available backups.
#. Check the backup you want to use and click :guilabel:`Restore Backup`.
#. In the :guilabel:`Launch Database` dialog box, specify the values you
want for the new database instance.
#. Click the :guilabel:`Restore From Database` tab and make sure that this
new instance is based on the correct backup.
#. Click :guilabel:`Launch`.
The new instance appears in the database instances list.
Update a database instance
~~~~~~~~~~~~~~~~~~~~~~~~~~
You can change various characteristics of a database instance,
such as its volume size and flavor.
To change the volume size of an instance
----------------------------------------
#. Log in to the dashboard.
#. From the CURRENT PROJECT on the :guilabel:`Project` tab, select the
appropriate project.
#. On the :guilabel:`Project` tab, open the :guilabel:`Database` tab and
click :guilabel:`Instances` category. This displays the existing
instances in your system.

fill in the :guilabel:`New Size` field with an integer indicating
the new size you want for the instance. Express the size in GB, and
note that the new size must be larger than the current size.
#. Click :guilabel:`Resize Database Volume`.
To change the flavor of an instance
-----------------------------------
#. Log in to the dashboard.
#. From the CURRENT PROJECT on the :guilabel:`Project` tab, select the
appropriate project.
#. On the :guilabel:`Project` tab, open the :guilabel:`Database` tab and
click :guilabel:`Instances` category. This displays the existing
instances in your system.
#. Check the instance you want to work with. In the
:guilabel:`Actions` column, expand the drop down menu and
select :guilabel:`Resize Instance`.
#. In the :guilabel:`Resize Database Instance` dialog box,
expand the drop down menu in the :guilabel:`New Flavor` field.
Select the new flavor you want for the instance.
#. Click :guilabel:`Resize Database Instance`.

===========================
Launch and manage instances
===========================
Instances are virtual machines that run inside the cloud.
You can launch an instance from the following sources:
* Images uploaded to the Image service.
* Image that you have copied to a persistent volume. The instance
launches from the volume, which is provided by the ``cinder-volume``
API through iSCSI.
* Instance snapshot that you took.
Launch an instance
~~~~~~~~~~~~~~~~~~
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Instances` category.
The dashboard shows the instances with its name, its private and
floating IP addresses, size, status, task, power state, and so on.
#. Click :guilabel:`Launch Instance`.
#. In the :guilabel:`Launch Instance` dialog box, specify the following values:
:guilabel:`Details` tab
Instance Name
Assign a name to the virtual machine.
Availability Zone
By default, this value is set to the availability zone given by the
cloud provider (for example, ``us-west`` or ``apac-south``). For some
cases, it could be ``nova``.
.. note::
The name you assign here becomes the initial host name of the server.
If the name is longer than 63 characters, the Compute service
truncates it automatically to ensure dnsmasq works correctly.
After the server is built, if you change the server name in the API
or change the host name directly, the names are not updated in the
dashboard.
Server names are not guaranteed to be unique when created so you
could have two instances with the same host name.
Count
To launch multiple instances, enter a value greater than ``1``. The
default is ``1``.
:guilabel:`Source` tab
Instance Boot Source
Your options are:
Boot from image
If you choose this option, a new field for :guilabel:`Image Name`
displays. You can select the image from the list.
Boot from snapshot
If you choose this option, a new field for :guilabel:`Instance
Snapshot` displays. You can select the snapshot from the list.
Boot from volume
If you choose this option, a new field for :guilabel:`Volume`
displays. You can select the volume from the list.
Boot from image (creates a new volume)
With this option, you can boot from an image and create a volume
by entering the :guilabel:`Device Size` and :guilabel:`Device
Name` for your volume. Click the :guilabel:`Delete Volume on
Instance Delete` option to delete the volume on deleting the
instance.
Boot from volume snapshot (creates a new volume)
Using this option, you can boot from a volume snapshot and create
a new volume by choosing :guilabel:`Volume Snapshot` from a list
and adding a :guilabel:`Device Name` for your volume. Click the
:guilabel:`Delete Volume on Instance Delete` option to delete the
volume on deleting the instance.
Image Name
This field changes based on your previous selection. If you have
chosen to launch an instance using an image, the :guilabel:`Image Name`
field displays. Select the image name from the dropdown list.
Instance Snapshot
This field changes based on your previous selection. If you have
chosen to launch an instance using a snapshot, the
:guilabel:`Instance Snapshot` field displays.
Select the snapshot name from the dropdown list.
Volume
This field changes based on your previous selection. If you have
chosen to launch an instance using a volume, the :guilabel:`Volume`
field displays. Select the volume name from the dropdown list.
If you want to delete the volume on instance delete,
check the :guilabel:`Delete Volume on Instance Delete` option.
:guilabel:`Flavor` tab
Flavor
Specify the size of the instance to launch.
.. note::
The flavor is selected based on the size of the image selected
for launching an instance. For example, while creating an image, if
you have entered the value in the :guilabel:`Minimum RAM (MB)` field
as 2048, then on selecting the image, the default flavor is
``m1.small``.
:guilabel:`Networks` tab
Selected Networks
To add a network to the instance, click the :guilabel:`+` in the
:guilabel:`Available` field.
:guilabel:`Network Ports` tab
Ports
Activate the ports that you want to assign to the instance.
:guilabel:`Security Groups` tab
Security Groups
Activate the security groups that you want to assign to the instance.
Security groups are a kind of cloud firewall that define which
incoming network traffic is forwarded to instances.
If you have not created any security groups, you can assign
only the default security group to the instance.
:guilabel:`Key Pair` tab
Key Pair
Specify a key pair.
If the image uses a static root password or a static key set
(neither is recommended), you do not need to provide a key pair
to launch the instance.
:guilabel:`Configuration` tab
Customization Script Source
Specify a customization script that runs after your instance
launches.
:guilabel:`Metadata` tab
Available Metadata
Add Metadata items to your instance.
#. Click :guilabel:`Launch Instance`.
The instance starts on a compute node in the cloud.
.. note::
If you did not provide a key pair, security groups, or rules, users
can access the instance only from inside the cloud through VNC. Even
pinging the instance is not possible without an ICMP rule configured.
You can also launch an instance from the :guilabel:`Images` or
:guilabel:`Volumes` category when you launch an instance from
an image or a volume respectively.
When you launch an instance from an image, OpenStack creates a local
copy of the image on the compute node where the instance starts.
For details on creating images, see `Creating images
manually <https://docs.openstack.org/image-guide/create-images-manually.html>`_
in the *OpenStack Virtual Machine Image Guide*.
When you launch an instance from a volume, note the following steps:
* To select the volume from which to launch, launch an instance from
an arbitrary image on the volume. The arbitrary image that you select
does not boot. Instead, it is replaced by the image on the volume that
you choose in the next steps.
To boot a Xen image from a volume, the image you launch in must be
the same type, fully virtualized or paravirtualized, as the one on
the volume.
* Select the volume or volume snapshot from which to boot. Enter a
device name. Enter ``vda`` for KVM images or ``xvda`` for Xen images.
.. note::
When running QEMU without support for the hardware virtualization, set
``cpu_mode="none"`` alongside ``virt_type=qemu`` in
``/etc/nova/nova-compute.conf`` to solve the following error:
.. code-block:: console
libvirtError: unsupported configuration: CPU mode 'host-model'
for ``x86_64`` qemu domain on ``x86_64`` host is not supported by hypervisor
Connect to your instance by using SSH
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To use SSH to connect to your instance, use the downloaded keypair
file.
.. note::
The user name is ``ubuntu`` for the Ubuntu cloud images on TryStack.
#. Copy the IP address for your instance.
#. Use the :command:`ssh` command to make a secure connection to the instance.
For example:
.. code-block:: console
$ ssh -i MyKey.pem ubuntu@10.0.0.2
#. At the prompt, type ``yes``.
It is also possible to SSH into an instance without an SSH keypair, if the
administrator has enabled root password injection. For more information
about root password injection, see `Injecting the administrator password
<https://docs.openstack.org/admin-guide/compute-admin-password-injection.html>`_
in the *OpenStack Administrator Guide*.
Track usage for instances
~~~~~~~~~~~~~~~~~~~~~~~~~
You can track usage for instances for each project. You can track costs
per month by showing meters like number of vCPUs, disks, RAM, and
uptime for all your instances.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click :guilabel:`Overview` category.
#. To query the instance usage for a month, select a month and click
:guilabel:`Submit`.
#. To download a summary, click :guilabel:`Download CSV Summary`.
Create an instance snapshot
~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Compute` tab and
click the :guilabel:`Instances` category.
#. Select the instance from which to create a snapshot.
#. In the actions column, click :guilabel:`Create Snapshot`.
#. In the :guilabel:`Create Snapshot` dialog box, enter a name for the
snapshot, and click :guilabel:`Create Snapshot`.

Log in to the dashboard
=======================
The dashboard is generally installed on the controller node.
#. Ask the cloud operator for the host name or public IP address from
which you can access the dashboard, and for your user name and
password. If the cloud supports multi-domain model, you also need to
ask for your domain name.
#. Open a web browser that has JavaScript and cookies enabled.
.. note::
To use the Virtual Network Computing (VNC) client for the dashboard,
your browser must support HTML5 Canvas and HTML5 WebSockets. The VNC
client is based on noVNC. For details, see `noVNC: HTML5 VNC
Client <https://github.com/kanaka/noVNC/blob/master/README.md>`__.

===================================
Create and manage object containers
===================================
OpenStack Object Storage (swift) is used for redundant, scalable data storage
using clusters of standardized servers to store petabytes of accessible data.
It is a long-term storage system for large amounts of static data which can be
retrieved and updated.
OpenStack Object Storage provides a distributed, API-accessible storage
platform that can be integrated directly into an application or used to
store any type of file, including VM images, backups, archives, or media
files. In the OpenStack dashboard, you can only manage containers and
objects.
In OpenStack Object Storage, containers provide storage for objects in a
manner similar to a Windows folder or Linux file directory, though they
cannot be nested. An object in OpenStack consists of the file to be
stored in the container and any accompanying metadata.
Create a container
~~~~~~~~~~~~~~~~~~
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.
#. Click :guilabel:`Container`.
#. In the :guilabel:`Create Container` dialog box, enter a name for the
container, and then click :guilabel:`Create`.
You have successfully created a container.
.. note::
To delete a container, click the :guilabel:`More` button and select
:guilabel:`Delete Container`.
Upload an object
~~~~~~~~~~~~~~~~
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.
#. Select the container in which you want to store your object.
#. Click the :guilabel:`Upload File` icon.
The :guilabel:`Upload File To Container: <name>` dialog box
appears.
``<name>`` is the name of the container to which you are uploading
the object.
#. Enter a name for the object.
#. Browse to and select the file that you want to upload.
#. Click :guilabel:`Upload File`.
You have successfully uploaded an object to the container.
.. note::
To delete an object, click the :guilabel:`More button` and select
:guilabel:`Delete Object`.
Manage an object
~~~~~~~~~~~~~~~~
**To edit an object**
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.
#. Select the container in which you want to store your object.
#. Click the menu button and choose :guilabel:`Edit` from the dropdown list.
The :guilabel:`Edit Object` dialog box is displayed.
#. Browse to and select the file that you want to upload.
#. Click :guilabel:`Update Object`.
.. note::
To delete an object, click the menu button and select
:guilabel:`Delete Object`.
**To copy an object from one container to another**
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.
#. Select the container in which you want to store your object.
#. Click the menu button and choose :guilabel:`Copy` from the dropdown list.
#. In the :guilabel:`Copy Object` launch dialog box, enter the following
values:
* :guilabel:`Destination Container`: Choose the destination container from
the list.
* :guilabel:`Path`: Specify a path in which the new copy should be stored
inside of the selected container.
* :guilabel:`Destination object name`: Enter a name for the object in the
new container.
#. Click :guilabel:`Copy Object`.
**To create a metadata-only object without a file**
You can create a new object in container without a file available and
can upload the file later when it is ready. This temporary object acts a
place-holder for a new object, and enables the user to share object
metadata and URL info in advance.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.
#. Select the container in which you want to store your object.
#. Click :guilabel:`Upload Object`.
The :guilabel:`Upload Object To Container`: ``<name>`` dialog box is
displayed.
``<name>`` is the name of the container to which you are uploading
the object.
#. Enter a name for the object.
#. Click :guilabel:`Update Object`.
**To create a pseudo-folder**
Pseudo-folders are similar to folders in your desktop operating system.
They are virtual collections defined by a common prefix on the object's
name.
#. Log in to the dashboard.
#. Select the appropriate project from the drop down menu at the top left.
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and
click :guilabel:`Containers` category.

are uploading the object.
#. Enter a name for the pseudo-folder.
A slash (/) character is used as the delimiter for pseudo-folders in
Object Storage.
#. Click :guilabel:`Create`.

Upload and manage images
========================
A virtual machine image, referred to in this document simply
as an image, is a single file that contains a virtual disk that
has a bootable operating system installed on it. Images are used
to create virtual machine instances within the cloud. For information
about creating image files, see the `OpenStack Virtual Machine
Image Guide <https://docs.openstack.org/image-guide/>`_.
Depending on your role, you may have permission to upload and manage
virtual machine images. Operators might restrict the upload and
management of images to cloud administrators or operators only. If you
have the appropriate privileges, you can use the dashboard to upload and
manage images in the admin project.

View and manage load balancers v2
=================================
Load-Balancer-as-a-Service (LBaaS) enables networking to distribute incoming
requests evenly among designated instances. This distribution ensures that
the workload is shared predictably among instances and enables more effective
use of system resources. Use one of these load-balancing methods to distribute
incoming requests:
* Round robin: Rotates requests evenly between multiple instances.
* Source IP: Requests from a unique source IP address are consistently
directed to the same instance.
* Least connections: Allocates requests to the instance with the
least number of active connections.
As an end user, you can create and manage load balancers and related
objects for users in various projects. You can also delete load balancers
and related objects.
LBaaS v2 has several new concepts to understand:
Load balancer
The load balancer occupies a neutron network port and
has an IP address assigned from a subnet.
Listener
Each port that listens for traffic on a particular load balancer is
configured separately and tied to the load balancer. Multiple listeners can
be associated with the same load balancer.
Pool
A pool is a group of hosts that sits behind the load balancer and
serves traffic through the load balancer.
Member
Members are the actual IP addresses that receive traffic from
the load balancer. Members are associated with pools.
Health monitor
Members may go offline from time to time and health monitors
diverts traffic away from members that are not responding properly.
Health monitors are associated with pools.
View existing load balancers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. Log in to the OpenStack dashboard.
#. On the :guilabel:`Project` tab, open the
:guilabel:`Network` tab, and click the
:guilabel:`Load Balancers` category.
This view shows the list of existing load balancers. To view details
of any of the load balancers, click on the specific load balancer.
Create a load balancer
~~~~~~~~~~~~~~~~~~~~~~
#. Log in to the OpenStack dashboard.
#. On the :guilabel:`Project` tab, open the
:guilabel:`Network` tab, and click the
:guilabel:`Load Balancers` category.
#. Click the :guilabel:`Create Load Balancer` button.
Use the concepts described in the overview section to fill in
the necessary information about the load balancer you want to create.
Keep in mind, the health checks routinely run against each instance
within a target load balancer and the result of the health check is
used to determine if the instance receives new connections.
.. note::
A message indicates whether the action succeeded.
Delete a load balancer
~~~~~~~~~~~~~~~~~~~~~~
#. Select the load balancer you want to delete
and click the :guilabel:`Delete Load Balancer` button.
To be deleted successfully, a load balancer must not
have any listeners or pools associated with
it. The delete action is also available in the
:guilabel:`Actions` column for the individual load balancers.

Create and manage volumes
=========================
Volumes are block storage devices that you attach to instances to enable
persistent storage. You can attach a volume to a running instance or
detach a volume and attach it to another instance at any time. You can
also create a snapshot from or delete a volume. Only administrative
users can create volume types.

========================
Launch and manage stacks
========================
OpenStack Orchestration is a service that you can use to
orchestrate multiple composite cloud applications. This
service supports the use of both the Amazon Web Services (AWS)
CloudFormation template format through both a Query API that
is compatible with CloudFormation and the native OpenStack
Heat Orchestration Template (HOT) format through a REST API.
These flexible template languages enable application
developers to describe and automate the deployment of
infrastructure, services, and applications. The templates
enable creation of most OpenStack resource types, such as
instances, floating IP addresses, volumes, security groups,
and users. Once created, the resources are referred to as
stacks.
The template languages are described in the `Template Guide
<https://docs.openstack.org/developer/heat/template_guide/index.
html>`_ in the `Heat developer documentation <http://docs.
openstack.org/developer/heat/>`_.
