Today, I broke this website while testing some minor changes to the deployment scripts. I tried to figure out what went wrong (I messed up something with Apache while trying to renew the SSL cert). I couldn’t get it sorted out so I blew up the droplet (VM, EC2 instance, whatever) and re-executed the existing playbooks. What enabled me to do this? How was I able to do this?<\/p>\n\n\n\n

Things that allowed me to recover:<\/strong><\/p>\n\n\n\n

  1. These scripts include daily backups so even if the entire WordPress deployment needs to be re-created from scratch, the data is tarred up and ready to go.<\/li>
  2. The website data is not stored on the VM but an attached persistent volume.<\/li>
  3. The database is a standalone, managed MySQL instance.<\/li>
  4. Playbooks and roles are designed to be idempotent so re-running them is safe. They aim for desired state<\/em> meaning no change if it’s not needed.<\/li><\/ol>\n\n\n\n

    How I recovered:<\/strong><\/p>\n\n\n\n

    So I simply destroyed the droplet, recreated it, and re-provisioned it. I had to perform a few tasks manually in DigitalOcean (whitelisting the droplet IP to the MySQL instance and pointing the floating IP to the new droplet) but even these tasks can<\/strong> be automated in the future (and will be).<\/p>\n\n\n\n

    All in all, I spent about an hour trying to figure out what I broke and another fifteen minutes to blow away and recreate the host. This is the way… Or at least, this is the way towards the way.<\/p>\n","protected":false},"excerpt":{"rendered":"
