Shared Cache Volumes

Currently Untested and Highly experimental

Documenting the proof-of-concept of creating a shared composer cache (PHP) directory and npm cache directory (NodeJS).

This can be used to share the local caches of downloaded packages between multiple project stacks.

Docksal does not have a mechanism to manage user created volumes. In the event that the volume needs to be dropped, you will need to stop all existing projects, drop/recreate the volume, and then do fin project reset cli in all projects that were mounting this external volume.

Run the following fin commands to create the volumes for caches:

fin docker volume create composer-cache
fin docker volume create npm-cache

Update docksal.yml respectively:

      - composer_cache:/home/docker/.composer/cache
      - npm_cache:/home/docker/.npm

    external: true
    external: true

(This is similar to how the global docksal_ssh_agent volume is mounted in cli.)

Update the project stack:

fin project start
