8.10. Protecting the Overcloud from Removal

PDF

To avoid accidental removal of the Overcloud with the heat stack-delete overcloud command, Heat contains a set of policies to restrict certain actions. Edit the /etc/heat/policy.json and find the following parameter:

"stacks:delete": "rule:deny_stack_user"

Change it to:

"stacks:delete": "rule:deny_everybody"

Save the file.

This prevents removal of the Overcloud with the heat client. To allow removal of the Overcloud, revert the policy to the original value.
