[question] bb_worker can't find /bin/fusermount

[havasd]

We are trying to setup the fuse based worker in our BB deployment in AWS EKS.

But upon startup we receive the following error:
Fatal error: rpc error: code = Unknown desc = Failed to expose build directory mount: Failed to create FUSE server: exec: \"/bin/fusermount\": stat /bin/fusermount: no such file or directory

I am not sure what is the expectation about fusermount? Are we suppossed to install it on the parent container? Or should it be actually part of the bb_worker image? Do we some more detailed documentation about the expectations around the infrastructure for the fuse based deployment?

Are you making sure you enable directMount: true in your FUSE mount options?

I believe you ran into the same issue as me. The real issue is not with fusermount but the actual error was swallowed by go-fuse, because when there is issue with direct mount, it falls back to fusermount.

The real issue for me is that my container was not running as root.

If you migrated to latest version of BuildBarn with this change(#156), you should be able to see the real error
