Docker GC

The missing garbage collector for docker

Installation

Binaries

I have pre-built binaries for several platform already. They are available on the releases page.

Container

I also have pre-built containers available on Docker Hub.

You can use this via docker run:

$ docker run -d -v /var/run/docker:/var/run/docker --name=gc docwhat/docker-gc:latest

Source

If you have go installed, then you can get the binary docker-gc with the following command:

$ go get -u -v github.com/docwhat/docker-gc

Usage

usage: docker-gc_darwin_amd64 [<flags>]

The missing docker garbage collector.

Flags:
  -h, --help                Show context-sensitive help (also try --help-long
                            and --help-man).
      --version             Show application version.
  -m, --max-image-age=168h  How old to allow images to be before deletion. (Env:
                            DOCKER_GC_MAX_IMAGE_AGE)
  -s, --sweeper-time=15m    How much time between running checks to delete
                            images. (Env: DOCKER_GC_SWEEPER_TIME)
  -d, --dangle-safe-duration=30m
                            How old should a dangle image be before deletion.
                            (Env: DOCKER_GC_DANGLE_SAFE_DURATION)
  -q, --quiet               Don't show any output. (Env: DOCKER_GC_QUIET)

It uses the normal Docker environment variables, so if docker info works, then docker-gc should work.
