The nightly playwright tests are currently failing because of a
mismatch between the expected version of Chromium and what's in the
container image. Unfortunately the previous specific tag we were using
for the container image is no longer tagged on the registry. With some
testing, I was able to find an image tag that results in a good run.
This test exercises upgrades between 0.8 and Nomad versions greater
than 0.9. We have not supported 0.8.x in a very long time and in any
case the test has been marked to skip because the downloader doesn't
work.
We moved off the old provisioning process for nightly E2E to one driven
entirely by Terraform quite a while back now. We're in the slow
process of removing the framework code for this test-by-test, but this
chunk of code no longer has any callers.
We don't need the absolute path for any of the commands in this script
so long as we `cd` into the source directory path. Doing this removes
the need for weird platform-specific tricks we have to do with
realpath vs GNU realpath.
The E2E test runner is running from the root of the Nomad
repository. Make this run independent of the working directory for
convenience of developers and the test runner.
The CSI plugin allocations take a while to be marked healthy,
sometimes causing E2E test flakes during the setup phase of the
tests. There's nothing CSI specific about marking plugin allocs
healthy, as the plugin supervisor hook does all the fingerprinting in
the postrun hook (the prestart hook just makes a couple of empty
directories). The timeouts we're seeing may be because of where we're
pulling the images from; most our jobs pull from a CDN-backed public
registry whereas these are pulling from ECR. Set a 1min timeout for
these to make sure we have enough time to pull the image and start the
task.
Scripts for running playwright tests in a Docker container that has
chromium and webkit preinstalled. Includes a basic smoke test for
authentication so that we can be sure the test rig is working
end-to-end. Wiring this up in CI will be in an upcoming PR.
Our E2E test environment is deployed with mTLS, but it's impractical
for us to use mTLS in headless browsers for automated testing (or even
in manual testing). Provide certificates for proxying the web UI via
Nginx. This proxy uses client certs for proxying to the HTTP endpoint
and a self-signed cert for the browser-facing endpoint. We can accept
certificate errors in the automated tests we'll be adding in the next
step of this work.
While working on infrastructure for testing the UI in E2E, we needed
to upgrade the certificate provider. Performing a provider upgrade via
the TF `init -upgrade` brought in updates for the file and AWS
providers as well. These updates include deprecating the use of
`sensitive_content` fields, removing CA algorithm parameters that can
be inferred from keys, and removing the requirement to manually
specify AWS assume role parameters in the provider config if they're
available in the calling environment's AWS config file (as they are
via doormat or our E2E environment).
This test has a failure that's happening only occassionally and not
very reproducibly. Print out the allocation status on test failure so
that we can do some post-mortum debugging of the test on nightly.
Many of our scripts have a non-portable interpreter line for bash and
use bash-specific variables like `BASH_SOURCE`. Update the interpreter
line to be portable between various Linuxes and macOS without
complaint from posix shell users.
This changeset fixes two sources of flakiness in the event stream test.
First, the stream request gets the event *closest* to the index, not
the exact match. Although events are written before raft entries
they're written asynchronously, so it's possible to race and get a
raft index from this query higher than the current head of the event
buffer. Ensure the job is running before we try to get the index, so
that we've given the event enough time to land in the buffer.
Second, the assertion that the found index is greater than the start
index is only true if the `PlanResult` event manages to land before we
do the second registration. Although it should now with the first fix
above, it's not a correct assertion for what we're testing.
The oversubscription test expects an output that requires the client
has polled the task for stats at least once. Wait long enough to
ensure that we've polled the stats before failing the test.
Some tests may chose to deregister jobs to check Nomad cleanup
logic, however, it is still possible for the test to fail and exit
before this is hit. This therefore adds a cancellable cleanup func
which can be deferred, using context to control whether it gets
run or not.
This change modifies the template task runner to utilise the
new consul-template which includes Nomad service lookup template
funcs.
In order to provide security and auth to consul-template, we use
a custom HTTP dialer which is passed to consul-template when
setting up the runner. This method follows Vault implementation.

Tear down the volume-consuming job between subtests, rather than after
all the tests are complete. For good measure, use a different ID for
the volume-consuming job as well.
* Wait longer for node to go down in disconnected clients test.
The existing helper only waits 10s, but there's a jitter on heartbeats
that we need to account for. Wait for 30s for node to go down to give
us plenty of room
* Port disconnected clients to stdlib-style test
Concurrent E2E runs can collide when provisioning policies on HCP
Consul and HCP Vault. Namespace these by the test run name, as we do
for most everything else.
Our E2E "framework" has a bunch of features around test discovery and
standing up infra that were never completed or fully used, and we
ended up building out a large test suite that ignored all that in lieu
of Terraform-provided infrastructure for the last couple years.
This changeset is a proposal (and demonstration) for gradually
migrating our E2E tests off the framework code so that developers can
write fairly ordinary golang stdlib testing tests.
This test exercises the behavior of clients that become disconnected
and have their allocations replaced. Future test cases will exercise
the `max_client_disconnect` field on the job spec.
* Use unix:// prefix for CSI_ENDPOINT variable by default
* Some plugins have strict validation over the format of the
`CSI_ENDPOINT` variable, and unfortunately not all plugins
agree. Allow the user to override the `CSI_ENDPOINT` to workaround
those cases.
* Update all demos and tests with CSI_ENDPOINT
The `ConnectACLsE2ETest` checks that the SI tokens have been properly
cleaned up between tests, but following the change to use HCP the
previous `Connect` test suite will often have SI tokens that haven't
been cleaned up by the time this test suite runs. Wait for the SI
tokens to be cleaned up at the start of the test to ensure we have a
clean state.
Use HCP Consul and HCP Vault for the Consul and Vault clusters used in E2E testing. This has the following benefits:
* Without the need to support mTLS bootstrapping for Consul and Vault, we can simplify the mTLS configuration by leaning on Terraform instead of janky bash shell scripting.
* Vault bootstrapping is no longer required, so we can eliminate even more janky shell scripting
* Our E2E exercises HCP, which is important to us as an organization
* With the reduction in configurability, we can simplify the Terraform configuration and drop the complicated `provision.sh`/`provision.ps1` scripts we were using previously. We can template Nomad configuration files and upload them with the `file` provisioner.
* Packer builds for Linux and Windows become much simpler.
tl;dr way less janky shell scripting!
This is a followup to having tests run in serial in CI.
The e2e package isn't in CI, but lets use the helper anyway
so we can setup semgrep rules covering the entire repository.
The RPC for listing volume snapshots requires a plugin ID. Update the
`volume snapshot list` command to find the specific plugin from the
provided prefix.
If any E2E test hangs, it'll eventually timeout and panic, causing the
all the remaining tests to fail. External commands should use a short
context whenever possible so we can fail the test quickly and move on
to the next test.
The `TestRescheduleProgressDeadlineFail` E2E test failed during test
cleanup because the error message "progress deadline expired" that it
emits when we stop the job does not match the one expected from
monitoring the `job stop` command. Update the `StopJob` helper to
tolerate this use case as well.
The `Metrics` suite uses prometheus to scrape Nomad metrics so that
we're testing the full user experience of extracting metrics from
Nomad. With the addition of mTLS, we need to make sure prometheus also
has mTLS configuration because the metrics endpoint is protected.
Update the Nomad client configuration and prometheus job to bind-mount
the client's certs into the task so that the job can use these certs
to scrape the server. This is a temporary solution that gets the job
passing; we should give the job its own certificates (issued by
Vault?) when we've done some of the infrastructure rework we'd like.
The AWS EBS plugin appears to use the name field of the volume as an
idempotency token that persists across the entire AWS account, not
just the plugin lifespan.
Also fix the regex for the volume ID, which was originally taken from
the job ID regex but isn't actually the same. This hasn't failed tests
for us because we've always passed in the same volume ID.
With mTLS enabled, using `curl` in a bash script for validation
involves having to configure arguments to `curl` based on whether or
not the test infrastructure is using mTLS, whether ACLs are enabled,
etc. Use the new `operator api` command instead to pick up the client
configuration from the test environment automatically.
PR #11550 changed the job stop exit behaviour when monitoring the
deployment. When stopping a job, the deployment becomes cancelled
and therefore the CLI now exits with status code 1 as it see this
as an error.
This change adds a new utility e2e function that accounts for this
behaviour.
