• Ansible openshift_quota_tier possible values:
  • xsmall
  • small
  • medium
  • large
  • xlarge

Default tier quota is small openshift_quota_tier=small

1. Apply Quota for multiple project

     ansible-playbook playbooks/openshift-quota/config.yml -e '{"openshift_quota_projects": ["myproject", "myproject-2"]}'
   

   Use a different tier:

     ansible-playbook playbooks/openshift-quota/config.yml -e '{"openshift_quota_projects": ["myproject", "myproject-2"]}' -e openshift_quota_tier=medium
   

2. Apply Quota for all projects

     ansible-playbook playbooks/openshift-quota/config.yml -e openshift_quota_all_projects=true
   

   openshift_quota_all_projects excludes the infrastructure projects:

   • default
   • kube-system
   • openshift-infra
   • openshift-metrics
   • openshift-grafana
   • grafana
   • openshift-service-catalog
   • openshift-glusterfs
   • glusterfs
   • storage
   • openshift-web-console
   • kube-service-catalog
   • kube-public
   • logging
   • management-infra
   • openshift-node
   • openshift-template-service-broker
   • openshift-ansible-service-broker
   • openshift-management
   • openshift

   To exclude additional projects use openshift_quota_projects_excluder as extra var

   ansible-playbook -i playbooks/openshift-quota/config.yml -e openshift_quota_all_projects=true -e '{"openshift_quota_projects_excluder": ["customer-infra", "customer-broker"]}'
   

3. View Current quota

    oc get quota,limitrange --all-namespaces --show-labels
