Change Details

I would like to rebuild the whole fleet of `integration-slave-docker` instances for a few reasons: # upgrade from Jessie to Stretch # reduce RAM from 32 to 24 by switching the flavor from `bigram` to `mediumram` (available since T225025) # in the hostname, replace `slave` by `agent` --- Steps: * On https://integration.wikimedia.org/ci/computer/ pick a node, put it offline, wait for jobs to complete and delete the agent * On https://horizon.wikimedia.org/project/instances/ ** Delete the instance ** Create a new instance named `integration-agent-docker-XXX` where XXXX increments starting from 1001 ** Pick the Stretch image ** Pick `mediumram` flavor Wait 3 or 4 minutes for the instance to be fully provisioned. Then on the instance: * rm -fR /var/lib/puppet/ssl && puppet agent -tv * if that complains: ** get the instance fully qualified domain name `hostname --fqdn` ** on integration-puppetmaster01.integration.eqiad.wmflabs: `sudo puppet cert clean <FQDN OF INSTANCE HERE>` Apply the puppet role * https://horizon.wikimedia.org/project/instances/ * Click the instance * Puppet tab * Pick `role::ci::slave::labs::docker` and set `docker_lvm_volume` to `True` * Run puppet on the instance * Make sure there is a partition for Docker * Upgrade and reboot: `sudo apt -y dist-upgrade && /usr/sbin/reboot` * Add the instance to Jenkins :]
