Exercises host volume and Docker volume functionality for the `exec` and `docker`
task driver, particularly around mounting locations within the container and
how this can be used with `template`.
The CLI helpers in the rescheduling test were intended for shared use, but
until some other tests were written we didn't want to waste time making them
generic. This changeset refactors them and adds some new helpers associated
with the node drain tests (under separate PR).
The E2E suite exercises the API, but not the CLI. This changeset adds a helper
function to send commands via a locally-built Nomad binary (which we'll need
to add to the E2E setup), and some helpers to parse the resulting structured
outputs in a way that tests can consume.
Adds 2 tests around Connect Native. Both make use of the example connect native
services in https://github.com/hashicorp/nomad-connect-examples
One of them runs without Consul ACLs enabled, the other with.
This changeset:
* adds eval status to the error messages emitted when we have
placement failure in tests. The implementation here isn't quite
perfect but it's a lot better than "condition not met".
* enforces the ordering of teardown of the CSI test
* doesn't pass the purge flag to one of the two CSI tests, so that we
exercise both code paths.
Extends the BasicAllocStats test to include a test for Windows
clients, exercising stats via a powershell `raw_exec` job.
Adds `ListLinuxClientNodes` and `ListWindowsClientNodes` utils so that
we can scope tests to run only when Linux or Windows clients are
available. This prevents waiting on timeouts when running a subset of
the tests against a development cluster (vs our nightly test
cluster).
- In script checks, ensure we're running `Exec` against the new running
allocation and not the earlier stopped one.
- In script checks, allow `Exec` calls to error due to lack of pty when
we use the exec to kill the task.
- In `utils.go/RegisterAllocs`, force query for allocations to wait on
wait index returned by registration call.
The e2e test code is absolutely hideous and leaks processes and files
on disk. NomadAgent seems useful, but the clientstate e2e tests are very
messy and slow. The last test "Corrupt" is probably the most useful as
it explicitly corrupts the state file whereas the other tests attempt to
reproduce steps thought to cause corruption in earlier releases of
Nomad.
