This commit adds some Prometheus metrics to /metrics in headscale.
It will add the standard go metrics, some automatic gin metrics and some
initial headscale specific ones.
Some of them has been added to aid debugging #97 (loop bug)
In the future, we can use the metrics to get rid of the sleep in the
integration tests by checking that our expected number of nodes has been
registered:
```
headscale_machine_registrations_total
```
This commit adds integration tests to headscale. They are currently
quite simple, but it lays the groundwork for more comprehensive testing
and ensuring we dont break things with the official tailscale client.
The test works by leveraging Docker (via dockertest) to spin up a
Headscale container, and a number of tailscale containers (10).
Each tailscale container is joined to the headscale and then "passed on"
to the tests.
Currently three tests have been implemented:
- Have all tailscale containers join headscale (in the setup process)
- Get IP from each container (I plan to extend this with cross-ping)
- List nodes with headscales CLI and verify all has been registered
This test depends on Docker, and currently, I have not looked into
hooking it into Github Actions.
This commit tries to detect if users can render colors in their terminal
and only enables color logs if that is true.
It also adds no-color.org's NO_COLOR env var support to allow it to be
disabled.
The issue was that our build pipeline uses 'go get' call to install
golint, which changed the go.mod/go.sum files (not good, but I hadn't
noticed before). Due to Golang bug #44129, this caused breakage on the
dependencies of certain modules we use.
The fix was to switch to 'go install golang.org/x/lint/golint@latest'.
The addition of '@latest' puts 'go install' in module aware mode, which
no longer changes go.mod file in the current directory. This is better,
and it also avoids bug #44129.
This commit also has a change due to `go mod tidy`. Finally, I had to
add a longer timeout for the golangci-lint installation step in the
github actions workflow, since that seems to take a bit over a minute
now. This step is usually cached on subsequent runs, so we hadn't seen
that failure before.
value from CreatePreAuthKey and GetPreAuthKeys. Add tests for that bug,
and the rest of the preauthkeys functionality.
Fix path in `compress` Makefile target.
