wordpress-operator Build Status

WordPress operator enables managing multiple WordPress installments at scale.

Goals and status

The main goals of the operator are:

  1. Easily deploy scalable WordPress sites on top of kubernetes
  2. Allow best practices for en masse upgrades (canary, slow rollout, etc.)
  3. Friendly to devops (monitoring, availability, scalability and backup stories solved)

The project is actively developed and maintained and has reached stable beta state. Check here the project releases.

Components

  1. WordPress operator - this project
  2. WordPress runtime - container image supporting the project goals (https://github.com/presslabs/runtime)
