Seth Hoenig 0f2d9ea915 e2e: wait 2m rather than 10s after disabling consul acls
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.

End to End Tests

This package contains integration tests.

The terraform folder has provisioning code to spin up a Nomad cluster on AWS. The tests work with the NOMAD_ADDR environment variable which can be set either to a local dev Nomad agent or a Nomad client on AWS.

Local Development

The workflow when developing end to end tests locally is to run the provisioning step described below once, and then run the tests as described below.

When making local changes, use ./bin/update $(which nomad) /usr/local/bin/nomad and ./bin/run sudo systemctl restart nomad to destructively modify the provisioned cluster.

Provisioning Test Infrastructure on AWS

You'll need Terraform and AWS credentials (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) to setup AWS instances on which e2e tests will run. See the README for details. The number of servers and clients is configurable, as is the configuration file for each client and server.

Provisioning e2e Framework Nomad Cluster

You can use the Terraform output from the previous step to generate a provisioning configuration file for the e2e framework.

# from the ./e2e/terraform directory
terraform output provisioning | jq . > ../provisioning.json

By default the provisioning.json will include a nomad_sha field for each node. You can edit this file to change the version of Nomad you want to deploy. Because each node has its own value, you can create cluster of mixed versions. The provisioning framework accepts any of the following options:

  • nomad_sha: This is a Nomad binary identified by its full commit SHA that's stored in a shared s3 bucket that Nomad team developers can access. That commit SHA can be from any branch that's pushed to remote. (Ex. "nomad_sha": "0b6b475e7da77fed25727ea9f01f155a58481b6c")
  • nomad_local_binary: This is a path to a Nomad binary on your own host. (Ex. "nomad_local_binary": "/home/me/nomad")
  • nomad_version: This is a version number of Nomad that's been released to HashiCorp. (Ex. "nomad_version": "0.10.2")

You can pass the following flags to go test to override the values in provisioning.json for all nodes:

  • -nomad.local_file=string: provision this specific local binary of Nomad
  • -nomad.sha=string: provision this specific sha from S3
  • -nomad.version=string: provision this version from releases.hashicorp.com

Deploy Nomad to the cluster:

# from the ./e2e/terraform directory, set your client environment
$(terraform output environment)

cd ..
go test -v . -provision.terraform ./provisioning.json -skipTests

Running

After completing the provisioning step above, you can set the client environment for NOMAD_ADDR and run the tests as shown below:

# from the ./e2e/terraform directory, set your client environment
# if you haven't already
$(terraform output environment)

cd ..
go test -v .

If you want to run a specific suite, you can specify the -suite flag as shown below. Only the suite with a matching Framework.TestSuite.Component will be run, and all others will be skipped.

go test -v -suite=Consul .

If you want to run a specific test, you'll need to regex-escape some of the test's name so that the test runner doesn't skip over framework struct method names in the full name of the tests:

go test -v . -run 'TestE2E/Consul/\*consul\.ScriptChecksE2ETest/TestGroup'
