Repository Management

Important

New as of 0.6.0

repo:gc <app>                            # Runs 'git gc --aggressive' against the application's repo
repo:purge-cache <app>                   # Deletes the contents of the build cache stored in the repository

The repository plugin is meant to allow users to perform management commands against a repository.

Usage

Git Garbage Collection

This will run a git gc --aggressive against the applications repo. This is performed on the Dokku host, and not within an application container.

dokku repo:gc node-js-app

Counting objects: 396, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (365/365), done.
Writing objects: 100% (396/396), done.
Total 396 (delta 79), reused 315 (delta 0)

Clearing Application cache

Building containers with buildpacks currently results in a persistent cache directory between deploys. If you need to clear this cache directory for any reason, you may do so by running the following shell command:

dokku repo:purge-cache node-js-app
