voodu images

Remove the docker images a host no longer needs.

Synopsis

voodu images prune [--dry-run] [--keep N]

Works on the box and from your machine, like every other command. The controller also runs this cleanup at 03:00 and 15:00 UTC. Set VOODU_IMAGE_PRUNE_SCHEDULE to another cron expression, or to off, to change that.

What stays

This is not docker image prune -a. An image stays when:

  • A container uses it, even a stopped one
  • A manifest names it
  • It is <app>:latest of a deployment, statefulset, job or cronjob
  • It is one of the newest --keep builds of a deployment or statefulset (default 5, the size of the release history)
  • It was tagged in the last hour

With --keep below 5, older releases stay in the history without their image, and voodu rollback to one fails with "image not present locally".

Build cache is not touched.

voodu stats

Live CPU and memory usage joined with the manifest's configured limits.

voodu config

Out-of-band env vars per app. See manifests/config for semantics.
