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.
Issue #7523 documents the Consul ACLs used in each Consul interface
used by Nomad. Minimize the policies used in e2e tests so that we
are setting a good example.
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.
This changeset adds volumes but does not mount them to instances so
that we can test the mounting ("staging") via CSI plugins. The CSI
plugins themselves will be installed as Nomad jobs.
In order to ensure we can always mount the EFS volume, this changeset
pins the deployment of the cluster to a specific subnet. In future
work we should spread the cluster out among several AZs and test that
behavior explicitly.
Golang 1.13 introduced a change in test flag parsing:
> testing
> ...
> Testing flags are now registered in the new Init function, which is invoked by the generated main function for the test. As a result, testing flags are now only registered when running a test binary, and packages that call flag.Parse during package initialization may cause tests to fail.
https://golang.org/doc/go1.13#testing
Here, we ensure that e2e framework parsing occur in TestMain, by only
initializing Framework at Run invocation.
go vet would have prevented the bug fixed in
6362e32161295fa959ebe46b93cea0ea1a9bdd72 but our use of errgroup
prevented that.
Rip out errgroup to take advantage of vet, and remove download limiting
now that we're downloading far fewer binaries overall.
Pretty sure Consul / Nomad clients are often not ready yet after
the ConsulACLs test disables ACLs, by the time the next test starts
running.
Running locally things tend to work, but in TeamCity this seems to
be a recurring problem. However, when running locally sometimes I do
see that the "show status" step after disabling ACLs, some nodes are
still initializing, suggesting we're right on the border of not waiting
long enough
nomad node status
ID DC Name Class Drain Eligibility Status
0e4dfce2 dc1 EC2AMAZ-JB3NF9P <none> false eligible ready
6b90aa06 dc2 ip-172-31-16-225 <none> false eligible ready
7068558a dc2 ip-172-31-20-143 <none> false eligible ready
e0ae3c5c dc1 ip-172-31-25-165 <none> false eligible ready
15b59ed6 dc1 ip-172-31-23-199 <none> false eligible initializing
Going to try waiting a full 2 minutes after disabling ACLs, hopefully that
will help things Just Work. In the future, we should probably be parsing the
output of the status checks and actually confirming all nodes are ready.
Even better, maybe that's something shipyard will have built-in.
Go implicitly treats files ending with `_linux.go` as build tagged for
Linux only. This broke the e2e provisioning framework on macOS once we
tried importing it into the `e2e/consulacls` module.
This changeset improves the ergonomics of running the Nomad e2e test
provisioning process by defaulting to a blank `nomad_sha` in the
Terraform configuration. By default, a user will now need to pass in
one of the Nomad version flags. But they won't have to manually edit
the `provisioning.json` file for the common case of deploying a
released version of Nomad, and won't need to put dummy values for
`nomad_sha`.
Includes general documentation improvements.
This test is causing panics. Unlike the other similar tests, this
one is using require.Eventually which is doing something bad, and
this change replaces it with a for-loop like the other tests.

Provide script for managing Consul ACLs on a TF provisioned cluster for
e2e testing. Script can be used to 'enable' or 'disable' Consul ACLs,
and automatically takes care of the bootstrapping process if necessary.
The bootstrapping process takes a long time, so we may need to
extend the overall e2e timeout (20 minutes seems fine).
Introduces basic tests for Consul Connect with ACLs.
This change allows for providing the -suite=<Name> flag when
running the e2e framework. If set, only the matching e2e/Framework.TestSuite.Component
will be run, and all ther suites will be skipped.
