registry-cleaner

Getting started

go install github.com/ViBiOh/registry-cleaner@latest

for repo in $(registry-cleaner -username "vibioh" -password "secret" -list); do
  registry-cleaner -username "vibioh" -password "secret" -image "${repo}" -grep ".*"
done

registry-cleaner -image "vibioh/fibr" -username "vibioh" -password "secret" -grep "[0-9]{12}" -last # keep only the last image that match regexp (which is a timestamp)

Golang binary is built with static link. You can download it directly from the GitHub Release page, use the above command line or build it by yourself by cloning this repo and running make.

You can configure app by passing CLI args or environment variables (cf. Usage section). CLI override environment variables.

Usage

The application can be configured by passing CLI args described below or their equivalent as environment variable. CLI values take precedence over environments variables.

Be careful when using the CLI values, if someone list the processes on the system, they will appear in plain-text. Pass secrets by environment variables: it's less easily visible.
