*: do not require env.sh

This removes the need to source env.{sh,fish} when working with hscloud.

This is done by:

 1. Implementing a Go library to reliably detect the location of the
    active hscloud checkout. That in turn is enabled by
    BUILD_WORKSPACE_DIRECTORY being now a thing in Bazel.
 2. Creating a tool `hscloud`, with a command `hscloud workspace` that
    returns the workspace path.
 3. Wrapping this tool to be accessible from Python and Bash.
 4. Bumping all users of hscloud_root to use either the Go library or
    one of the two implemented wrappers.

We also drive-by replace tools/install.sh to be a proper sh_binary, and
make it yell at people if it isn't being ran as `bazel run
//tools:install`.

Finally, we also drive-by delete cluster/tools/nixops.sh which was never used.

hscloud is the main monorepo of the Warsaw Hackerspace infrastructure code.

Getting started

See //doc/codelabs for tutorials on how to use hscloud.

If you want to browse the source of hscloud in a web browser, use cs.hackerspace.pl.

If you want some other help, talk to q3k, informatic or your therapist.

Directory Structure

Directories you should care about:

  • app: external services that we host that are somewhat universal: matrix, covid-formity, etc.
  • bgpwtf: code related to our little ISP
  • cluster: code related to our Kubernetes cluster (k0.hswaw.net)
  • dc: code related to datacenter automation
  • devtools: code related to developer tooling, like gerrit or hackdoc
  • doc: high-level documentation that doesn't fit anywhere else, ie. codelabs
  • hswaw: Warsaw Hackerspace specific/internal services. The line between this and app is unfortunately blurry.
  • personal: user's personal (experimental) directories
  • kube, go: code specific to languages but general to the whole of hscloud

Licensing

Unless noted otherwise, code in hscloud is licensed under the BSD 0-clause license - see COPYING.
