This PR enables jobs configured with a custom sidecar_task to make
use of the `service.expose` feature for creating checks on services
in the service mesh. Before we would check that sidecar_task had not
been set (indicating that something other than envoy may be in use,
which would not support envoy's expose feature). However Consul has
not added support for anything other than envoy and probably never
will, so having the restriction in place seems like an unnecessary
hindrance. If Consul ever does support something other than Envoy,
they will likely find a way to provide the expose feature anyway.
Fixes#9854
The connect tests are very disruptive: restart consul/nomad agents with new
tokens. The test seems particularly flaky, failing 32 times out of 73 in my
sample.
The tests are particularly problematic because they are disruptive and affect
other tests. On failure, the nomad or consul agent on the client can get into a
wedged state, so health/deployment info in subsequent tests may be wrong. In
some cases, the node will be deemed as fail, and then the subsequent tests may
fail when the node is deemed lost and the test allocations get migrated unexpectedly.
* Prevent Job Statuses from being calculated twice
https://github.com/hashicorp/nomad/pull/8435 introduced atomic eval
insertion iwth job (de-)registration. This change removes a now obsolete
guard which checked if the index was equal to the job.CreateIndex, which
would empty the status. Now that the job regisration eval insetion is
atomic with the registration this check is no longer necessary to set
the job statuses correctly.
* test to ensure only single job event for job register
* periodic e2e
* separate job update summary step
* fix updatejobstability to use copy instead of modified reference of job
* update envoygatewaybindaddresses copy to prevent job diff on null vs empty
* set ConsulGatewayBindAddress to empty map instead of nil
fix nil assertions for empty map
rm unnecessary guard
* adds two base event stream e2e tests
test evaluation filter keys are included
* Apply suggestions from code review

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`.
Ports the rescheduling tests (which aren't running in CI) into the current
test framework so that they're run on nightly, and exercises the new CLI
helpers.

This changeset provides two basic e2e tests for CSI plugins targeting
common AWS use cases.
The EBS test launches the EBS plugin (controller + nodes) and registers
an EBS volume as a Nomad CSI volume. We deploy a job that writes to
the volume, stop that job, and reuse the volume for another job which
should be able to read the data written by the first job.
The EFS test launches the EFS plugin (nodes-only) and registers an EFS
volume as a Nomad CSI volume. We deploy a job that writes to the
volume, stop that job, and reuse the volume for another job which
should be able to read the data written by the first job.
The writer jobs mount the CSI volume at a location within the alloc
dir.
The e2e framework instantiates clients for Nomad/Consul but the
provisioning of the actual Nomad cluster is left to Terraform. The
Terraform provisioning process uses `remote-exec` to deploy specific
versions of Nomad so that we don't have to bake an AMI every time we
want to test a new version. But Terraform treats the resulting
instances as immutable, so we can't use the same tooling to update the
version of Nomad in-place. This is a prerequisite for upgrade testing.
This changeset extends the e2e framework to provide the option of
deploying Nomad (and, in the future, Consul/Vault) with specific
versions to running infrastructure. This initial implementation is
focused on deploying to a single cluster via `ssh` (because that's our
current need), but provides interfaces to hook the test run at the
start of the run, the start of each suite, or the start of a given
test case.
Terraform work includes:
* provides Terraform output that written to JSON used by the framework
to configure provisioning via `terraform output provisioning`.
* provides Terraform output that can be used by test operators to
configure their shell via `$(terraform output environment)`
* drops `remote-exec` provisioning steps from Terraform
* makes changes to the deployment scripts to ensure they can be run
multiple times w/ different versions against the same host.
Adds Windows targets to the client/allocs metrics tests. Removes the
`allocstats` test, which covers less than these tests and is now
redundant.
Adds a firewall rule to our Windows instances so that the prometheus
server can scrape the Nomad HTTP API for metrics.
Refactor the metrics end-to-end tests so they can be run with our e2e
test framework. Runs fabio/prometheus and a collection of jobs that
will cause metrics to be measured. We then query Prometheus to ensure
we're publishing those allocation metrics and some metrics from the
clients as well.
Includes adding a placeholder for running the same tests on Windows.
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.
