Installation with Keystone
Note
Use of keystone with bifrost is a very new feature and should be considered an advanced topic. Please feel free to reach out to the bifrost contributors and the ironic community as a whole in the project's IRC channel.
Bifrost can now install and make use of keystone. In order to enable
this as part of the installation, the enable_keystone
variable must be set to true
, either in
playbooks/inventory/group_vars/target
or on the command
line during installation. Note that enable_keystone and noauth_mode are
mutually exclusive so they should have an opposite value of oneanother.
Example:
ansible-playbook -vvvv -i inventory/target install.yaml -e enable_keystone=true -e noauth_mode=false
However, prior to installation, overriding credentials should be set in order to customize the deployment to meet your needs. At the very least, the following parameters should be changed for a production environment:
admin_password
-
Password for the bootstrap user (called
admin
by default). default_password
-
Password for the regular user (called
bifrost_user
by default). service_password
-
Password for communication between services (never exposed to end users).
If any of these values is not set, a random password is generated
during the initial installation and stored on the controller in an
accordingly named file in the ~/.config/bifrost
directory
(override using password_dir
).
See the following files for more settings that can be overridden:
playbooks/roles/bifrost-ironic-install/defaults/main.yml
playbooks/roles/bifrost-keystone-install/defaults/main.yml
Using an existing Keystone
If you choose to install bifrost using an existing keystone, this
should be possible, however it has not been tested. In this case you
will need to set the appropriate defaults, via
playbooks/roles/bifrost-ironic-install/defaults/main.yml
which would be a good source for the role level defaults. Ideally, when
setting new defaults, they should be set in the
playbooks/inventory/group_vars/target
file.
Creation of clouds.yaml
By default, during bifrost installation, when keystone is enabled, a
file will be written to the user's home directory that is executing the
installation. That file can be located at
~/.config/openstack/clouds.yaml
. The cloud that is written
to that file is named bifrost
.
Creation of openrc
Also by default, after bifrost installation and again, when keystone is enabled, a file will be written to the user's home directory that you can use to set the appropriate environment variables in your current shell to be able to use OpenStack utilities:
. ~/openrc bifrost && openstack baremetal driver list
