openstack-helm-plugin/wait-for-pods.sh
Vladimir Kozhukalov 4b4f8c3412 Initial commit
The plugin provides some convenience for end users
when they deploy Openstack using OSH charts.

There are two plugin subcommands:
- get-values-overrides - generates values
  overrides file names from a set of given feature gates.
  If these files not found then it can try to
  download them via HTTP.
- wait-for-pods - checks if all the containers of all running pods
  are ready and if all jobs are successfully completed.
