Overview

The procedures in this runbook require project admin permissions to complete.

Error / Incident

There's some stale certificates on the puppetmaster after the removal of some VMs.

Common issues

This usually happens after manually removing a VM in a project that has it's own puppetmaster.

If this is the case, you can check the fqdns that were removed in the following graph (search for relevant project): https://grafana-labs.wikimedia.org/d/MaLO-EpZk/puppet-failures?orgId=1

then with the list of failed fnqdns, follow the guideline here: https://wikitech.wikimedia.org/wiki/Puppet#node_cleanup

To avoid, you can use the dedicated cookbook to remove the instances: 

dcaro@vulcanus$ cookbook wmcs.vps.remove_instance --help
usage: cookbooks.wmcs.vps.remove_instance [-h] [--project PROJECT] [--task-id TASK_ID] [--no-dologmsg] [--revoke-puppet-certs] --server-name SERVER_NAME

WMCS Toolforge - Remove an instance from a project.

Usage example:
    cookbook wmcs.vps.remove_instance \
        --project toolsbeta \
        --server-name toolsbeta-k8s-test-etcd-08

options:
  -h, --help            show this help message and exit
  --project PROJECT     Relevant Cloud VPS openstack project (for operations, dologmsg, etc). If this cookbook is for hardware, this only affects dologmsg calls. Default
                        is 'admin'.
  --task-id TASK_ID     Id of the task related to this operation (ex. T123456). (default: None)
  --no-dologmsg         To disable dologmsg calls (no SAL messages on IRC). (default: False)
  --revoke-puppet-certs
                        If set, the Puppet certificates of this server will be revoked on a custom Puppetmaster (default: False)
  --server-name SERVER_NAME
                        Name of the server to remove (without domain, ex. toolsbeta-test-k8s-etcd-9). (default: None)
