Deckschrubber inspects images of a Docker Registry and removes those older than a given age.
go get github.com/fraunhoferfokus/deckschrubber
$GOPATH/bin/deckschrubberWe run our own private registry on a server with limited storage and it was only a question of time, until it was full! Although there are similar approaches to do Docker registry house keeping (in Python, Ruby, etc), a native module (using Docker's own packages) was missing. This module has the following advantages:
- Is binary!: No runtime, Python, Ruby, etc. is required
- Uses Docker API: same packages and modules used to relaze Docker registry are used here
-day int
max age in days
-debug
run in debug mode
-dry
does not actually deletes
-latest int
number of the latest matching images of an repository that won't be deleted (default 1)
-month int

-registry string

-repo string

-repos int
number of repositories to garbage collect (default 5)
-tag string
matching tags (allows regexp) (default ".*")
-ntag string

-v shows version and quits
-year int
max age in days

$GOPATH/bin/deckschrubber -month 2 -day 2
- Remove all images older than 1 year from

$GOPATH/bin/deckschrubber -year 1 -registry http://myrepo:5000
- Analyize (but do not remove) images of 30 repositories
$GOPATH/bin/deckschrubber -repos 30 -dry
