kolla-ansible start at a particular task

[admin0]

Hi,

ansible ha this feature:

ansible-playbook playbook.yml --start-at-task="task A"

Checking if similar feature can be implemented to kolla-ansible.

This is during the deploy phase when things go wrong, and you have to fix (something in the global or in the environment) and start again. This will help save time so that all roles/systems that have been deployed does not need to be re-run. and it can start from the role it failed.

For example, if cinder failed, no need to wait for it to redo database, rabbit, keystone, nova, neutron, glance etc before reaching cinder.

If a similar feature or step exists to do the same, please let us know how to achieve it.

Hi. You can specify additional options for ansible-playbook via the EXTRA_OPTS environment variable. We should document this.

I'd also say that in general you can't assume that tasks are not interdependent, especially within a role. I would suggest using --tags and occasionally --limit instead.
