Test openjdk 8 package upgrades on eqiad stretch hosts
Closed, ResolvedPublic
Actions

Description

Per email with @MoritzMuehlenhoff , security updates are available for OpenJDK 8.

Will test these package updates on eqiad hosts using the following restrictions:

  • One host per row
  • No masters

Plan:

  • Announce start of work in #wikimedia-operations
  • Depool host and wait 2 minutes for traffic to cease.
  • Apply package updates
  • Restart Elastic services
  • Wait for all clusters to go back to green.

Repeat 2 more times.

Once I have successfully upgraded 3 hosts, I will consider this a success, and will fold in the upgrade to the larger operation described in T309720 .

All canary hosts successfully, rolled out the package to all eqiad hosts via cumin:
sudo cumin "A:stretch and P{elastic*.eqiad.wmnet}" 'sudo apt-get install -y --only-upgrade openjdk-8-jre-headless'
