local: Add bindle release build for better Linux compat

[lann]

ref #58

[lann]

These binaries seem to work. They could just be checked in to the repo, or they could be artifacts on the github release.

[vdice]

A thought: If we added Docker as a dep for the local installer, we could run bindle via the container from the Dockerfile in this PR (bindle.nomad switches to use the docker driver). WDYT? Decided no go for this use case.

This works for me locally

[vdice]

This worked well for me (on Mac) -- so, a test to ensure default behavior is maintained. I believe @lann also tested on a Linux box to vet the bindle-server URL. Wondering if @bacongobbler will have a chance to try this out and sign off?

[lann]

Would be nice if @itowlson could test too on Ye Olde Linuks

Fails on 18.04 LTS, I'm afraid.

With no diagnostics, which is vexing - our script keeps retrying until timeout, but Nomad itself seems to provide absolutely no logs of process startup errors - surely they must be there somewhere?! Anyway, it works for me on 20.04 so I assume it's Hamster Stonehenge issues rather than WSL issues, but can't confirm for certain...!

Dang, I thought I had tested on an 18.04 image, but someone on Discord had issues on Mint 19.3 which is based on 18.04. The build uses debian buster which I thought would make the binary compatible with 18.04 but clearly I was mistook. In that discord thread we discussed the possibility of even staticallier-linking against musl libc for better portability, but a quick experiment replacing the build base image lead to bizarro segfaults in the build process.

This incantation seems to work; at least it gives you an exit code...

Yeah but I wanted stderr to figure out why it exited with code 2.
