Add supplemental node provisioner
Add ability to deploy a supplemental node along with undercloud and overcloud nodes by the libvirt/setup role(s) along with basic ability to deploy TLS everywhere. - Update tripleo-inventory role to allow for configuring supplmental node host access - Update common role defaults with required vars - Update quickstart.sh to support fake HA IPA deployment - Update general_config/ipa.yml with relevant vars - Add nodes/1ctlr_1comp_1supp.yml for supplmental node deployment - Add release note Depends-On: I53323511aabf0d616805efab6edde4acc7bedf11 Related-Bug: 1662923 Change-Id: I3f18e26d0e40942c7c54c07b644ee1209fb89c83

libvirt/setup/supplemental
|
||||
==========================
|
||||
|
||||
An Ansible role for provisioning a supplemental node prior to deployment
|
||||
of the TripleO undecloud
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
This role pairs with the libvirt/setup role to provision a supplemental node
|
||||
VM.
|
||||
|
||||
The role expects to be provided with a `supplemental_provision_script` which
|
||||
will be copied to the virthost during execution and is responsible for
|
||||
preparing the the vm's image and adding it to the proper libvirt pool.
|
||||
Furthermore, the `supplemental_node_ip` must be configured by this script and
|
||||
it will be used to add the host to ansible in-memory inventory as well as
|
||||
in preparation of ssh config files by the tripleo-inventory role.
|
||||
|
||||
**Note:** If `enable_tls_everywhere` is true, this role will provision the
|
||||
supplemental node for deployment of a FreeIPA server using the
|
||||
`tls_everywhere_provisioner.sh` script in lieu of the `supplemental_provision_script`.
|
||||
|
||||
Role Variables
|
||||
--------------
|
||||
|
||||
supplemental_node_key: "{{ local_working_dir }}/id_rsa_supplemental"
|
||||
supplemental_base_image_url: https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2
|
||||
|
||||
* `deploy_supplemental_node` -- <false> if true, provision supplemental node
|
||||
* `supplemental_node_key` -- Location of key to be used for access to
|
||||
supplemental node vm.
|
||||
* `supplemental_base_image_url` -- URL of base image to be provisioned against
|
||||
* `supplemental_node_ip` -- IP which provisioned node will be externally accessible from
|
||||
* `supplemental_provisioning_script` -- Path to script which will be copied to and run from the
|
||||
virthost to provision the vm image
|
||||
* `supplemental_user` -- <stack> The user which is used to deploy the supplemental node
|
||||

||||
