Server Patching Procedure (Outage window required)

  • Inform Instance members of planned outage
  • shutdown now (shut down server)
  • Take AMI Image of server
  • Take backup of DB (RDS Snapshot is online backup)
  • Start up server again
  • Apply server patches
  • Reboot if kernel patches
  • Docker should bring the containers back online automaticly.

Mastodon Docker Live Upgrade Procedure (Limited outage window required)

  • Read the upgrade details - the Docker specific details are generally documented by Gargron.
  • git fetch
  • git stash
  • git checkout <version>
  • git stash pop
  • edit docker-compose.yml if required (pop should restore the docker-compose.yml)
  • docker-compose build
  • docker-compose run --rm web bundle exec rake db:migrate (optional)
  • docker-compose up -d

Notice: The process does not require docker-compose down because the docker-compose build will create the image in the background and docker-compose up -d will upgrade automaticly.
