Used to clone the Galaxy tools from CVMFS to a bucket.
This is done to allow others to provide their own tool suite, to eliminate the need for CVMFS on startup, and to speed up the Galaxy startup time.
Defining which tools are included in the default installation is governed by the usegalaxy-tools/cloud repo, which places the tool definitions onto Galaxy's CVMFS. The code in this repo uses GitHub Actions to mount CMVFS, create archives of the tool definitions, and places copies of the archives to a public GCP bucket. When Galaxy is deployed using Galaxy Helm, these archives are retrieved at startup, providing tool definitions in Galaxy.
There are 3 archives in total, startup, partial, and full. The startup
one contains Galaxy configuration files and tool XML wrappers. The archive is a
few MB in size and this is enough information for Galaxy handlers to start. The
partial archive is a couple hundred MB and it also includes any tool scripts
allowing the tools to actually run when invoked. The full archive (~1.2GB)
includes the tool test data so it can be used as part of tool testing infrastructure.
