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.

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 not include the Nomad version
that will be deployed to each node. You can pass the following flags
to go test to set the version for all nodes:
-nomad.local_file=string: provision this specific local binary of Nomad. This is a path to a Nomad binary on your own host. Ex.-nomad.local_file=/home/me/nomad-nomad.sha=string: provision this specific sha from S3. 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.version=string: provision this version from releases.hashicorp.com. Ex.-nomad.version=0.10.2
Then deploy Nomad to the cluster by passing -provision.terraform
without a Nomad version flag:
go test -v . -nomad.version=0.10.2 -provision.terraform ./provisioning.json -skipTests
Because it can take a little while for the cluster to settle, it's
recommended to run this provisioning step (with -skipTests) first,
and then run tests as separate step.
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
$(terraform output environment)
cd ..
go test -v .
If you want to run a specific suite, you can specify the -suite flag as
shown below. Only the suite with a matching Framework.TestSuite.Component
will be run, and all others will be skipped.
go test -v -suite=Consul .
If you want to run a specific test, you'll need to regex-escape some of the test's name so that the test runner doesn't skip over framework struct method names in the full name of the tests:
go test -v . -run 'TestE2E/Consul/\*consul\.ScriptChecksE2ETest/TestGroup'
I Want To...
...SSH Into One Of The Test Machines
You can use the Terraform output to find the IP address. The keys will
in the ./terraform/keys/ directory.
ssh -i keys/nomad-e2e-*.pem ubuntu@${EC2_IP_ADDR}
...Deploy a Cluster of Mixed Nomad Versions
The provisioning.json file output by Terraform has a blank field for
nomad_sha for each node of the cluster (server and client). You can
manually edit the file to replace this value with a nomad_sha,
nomad_local_binary, or nomad_version for each node to create a
cluster of mixed versions. The provisioning framework accepts any of
the following options for those fields:
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")
Then deploy Nomad to the cluster by passing -provision.terraform
without a Nomad version flag:
go test -v . -provision.terraform ./provisioning.json -skipTests
...Deploy Custom Configuration Files
The provisioning.json file includes a bundles section for each
node of the cluster (server and client). You can manually edit this
file to add, remove, or replace
"bundles": [
{
"destination": "/ops/shared/nomad/base.hcl",
"source": "/home/me/custom.hcl"
}
]
...Deploy More Than 4 Linux Clients
Right now the framework doesn't support this out-of-the-box because of
the way the provisioning script adds specific client configurations to
each client node (for constraint testing). You'll need to add
additional configuration files to
./e2e/terraform/shared/nomad/indexed.
