When I discovered Pantheon in early 2017 I thought I’d found an a hidden gem. The honeymoon ended when Pantheon hiked costs 40% (while taking away Redis) after about six months on their platform. That was a bummer, but not a deal breaker.
Fast-forward three years and Pantheon struck again. Only this time intead of instead of another 40% increase they went for the whole cookie jar with a jaw-dropping 1185.71% increase to $450 per month with a 10-day lead on the bill.
With little time to react to Pantheon’s change I did the most reasonable thing I could think of: let the site go down while I learned to move it to Kubernetes.
- Get site back up-and-running with the least amount of effort
- Eliminate visitor-based pricing imposed by hosting company
- Use minimum possible resources to run WordPress at scale
- Restore Redis cache Pantheon used to offer with $25 hosting
The rest of this post describes how I moved the Chicago Gang History WordPress website off Pantheon and onto Kubernetes. If you follow this guide, you can retrace my footsteps to migrate from Pantheon to Kubernetes too. At the outset you’ll have a 3-node WordPress cluster on Digital Ocean for $30 a month.
