cache-apt-pkgs-action

This action allows caching of Advanced Package Tool (APT) package dependencies to improve workflow execution time instead of installing the packages on every run.

Documentation

This action is a composition of actions/cache and the apt utility. Some actions require additional APT based packages to be installed in order for other steps to be executed. Packages can be installed when ran but can consume much of the execution workflow time.

Usage

Pre-requisites

Create a workflow .yml file in your repositories .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file.

Inputs

packages - Space delimited list of packages to install.
version - Version of cache to load. Each version will have its own cache. Note, all characters except spaces are allowed.
refresh - Refresh / upgrade the packages in the same cache.

Outputs

cache-hit - A boolean value to indicate a cache was found for the packages requested.
package_version_list - The packages and versions that are installed as a comma delimited list with colon delimit on the package version (i.e. <package1>:<version1>,<package2>:<version2>,...).

Cache scopes

The cache is scoped to the packages given and the branch. The default branch cache is available to other branches.

Example workflow

This was a motivating use case for creating this action.

Cache Limits

A repository can have up to 5GB of caches. Once the 5GB limit is reached, older caches will be evicted based on when the cache was last accessed. Caches that are not accessed within the last week will also be evicted.
