cjengineering/codeship-warm-cache repository overview

Warm local caches in a step. In Codeship Jet, the cached property of a service enables a branchname-based cache-warming scheme. The trouble is that it kicks in for both local and CI builds, forcing a pull even when building locally. This image attempts to move cache configuration into a step where it can be skipped with tag predicates.

The command should be a bare repository (no tag). The container uses the CI_BRANCH environment to determine if it should pull from a branch-specific tag (it uses branch-${CI_BRANCH}).
