Dependencies for a pure artifact server are undocumented

Background

We document an alternate install path for artifact-server-only BuildStream here, but we do not list the dependencies of the server.

Task description

We should document the dependencies of the artifact server, since they will differ from main BuildStream. In particular, I believe neither fuse nor bubblewrap are required.

• Figure out the actual dependencies of the artifact server
• Ensure that the installation path works without unnecessary dependencies
• Document the new list of dependencies
• Update the relevant docker image

Acceptance Criteria

We should have a clearly documented set of dependencies for the artifact server.

---

Interestingly, running the artifact server seems to load the fuse.py file, which will fail if libfuse is not available. This might be a bug.

changed milestone to %BuildStream_v1.4

added Important label

At this time, the plan is not to supply an artifact server with bst-2.

If we decide to supply an artifact server which is a small wrapper around buildbox-casd, then we will have to document the installation... until then, closing this as it is obsolete.
