A simple way to bootstrap a bunch of VMs on a libvirt host. Gives more control than quickstart in some cases.
Please run the following command in order to get "tripleo operator" collection:
ansible-playbook config-host.yaml
It is expected to run the following resources:
- 1 undercloud
- 3 controllers
- 2 computes
- 3 ceph-storage
The amount of used memory for that env is about 52G, and about 20 CPU cores.
A working ssh-agent must be running on the host launching ansible playbook. It is needed in order to hot-load the private ssh key for the undercloud access.
In case you're running the playbook for a "middle machine", you can just forward the agent from your workstation.
ansible-playbook builder.yaml
It will deploy a containerized undercloud and prepare the baremetal.json file you will use in order to register nodes in ironic.
If you issue a lab-destroy
on the builder, you will need to redeploy the
lab:
ansible-playbook builder.yaml --tags lab
Just limit with the tags, and be sure to have the inventory
tag. For
example, in order to just manage the overcloud images:
ansible-playbook builder.yaml -t inventory,overcloud-images
Just add the requested information in the yaml you used for the initial deploy, then:
ansible-playbook builder.yaml -t domains -t baremetal -t vbmc
Domain tag will create the instance disk image and add it to libvirt. The vbmc tag will add the new to vbmc, and enable it. The baremetal tag will take care of the different configuration on the undercloud.
One note though: you might want to delete the already-existing node(s) from the baremetal.json on the undercloud, in order to avoid useless error output from the import task.
Also, this ansible will NOT run the import task once more, it doesn't ensure all nodes are present. You will need to run, on your own:
source ~/stackrc
openstack overcloud node import --provide baremetal.json
You can pass variables and environment files using the -e
option, like:
ansible-playbook builder.yaml --skip-tags overcloud-images --tags lab -e @environments/3ctl-1compute.yaml
This will start a lab with just 3 controllers and 1 compute.

synchronize List of hashes with the following entries:
