Super simple cli tool written in Go to clean your v2 docker registry.

File main.go is the entrypoint of the program.

• go
• make

Multiple flags are settable, some are mandatory, help menu will help you. All flags have a shortcut alias.

Three commands :

• showimages : show all images in the registry
• showtags : show all tags associated with image
• delete : delete all tags according to provided flags to the program

To use this project you can simply use go run or launch the binary.

Show all images in the registry :

go run main.go showimages -u https://registry.docker.example.com
# or
go-clean-docker-registry showimages -u https://registry.docker.example.com

If previous timeout, show first 100 images in the registry :

go-clean-docker-registry showimages -u https://registry.docker.example.com -n 100
