#269 Docker Housekeeping

Some simple housekeeping commands for Docker.

Notes

Problem: no space left on device when trying to build an image, but there is apparently lots of disk space left?

Cleanup Commands

docker system prune

This will remove:

• all stopped containers
• all networks not used by at least one container
• all dangling images
• all dangling build cache

docker image prune

This will remove:

• all dangling images

docker volume prune

This will remove:

• all local volumes not used by at least one container

docker buildx prune

Removes build cache.

Using Until Filter

These commands accept an until.

Relative times are allowed e.g.

docker image prune --filter "until=48h"

in addition to absolute date e.g.

docker image prune --filter "until=2021-07-01"
