adhoc-openshift-pv.yml

---
# This playbook is to create a persistent volume for openshift CI namespace
# Needed variables as extra-vars:
#  - pv_size (like 100Gi)
#  - cico_project_name (registry)
#  - host (where to execute command, like ocp-admin.ci.centos.org)
# Example to run the playbook
# ansible-playbook-ci playbooks/adhoc-openshift-pv.yml -e "host=n4-136.cloud.ci.centos.org" -e "pv_size=10Gi" -e "cico_project_name=test" 
# The node on which we'll run this should have the exported NFS volume mounted locally
# using variables from inventory:
#   ocp_nfs_server: (like node.domain)
#   ocp_nfs_export: ocp-staging
