The call to IMDSv1 has been failing since we switched to v2 which meant the UI e2e script attempted to use the service IP address for its tests. The service IP address is the Nomad client's private address which is not routable from the e2e test runner which means the test fails. This change updates the IP discovery to use IMDSv2 which means the address is correctly populated and routable. The change also makes this discovery method by a job action within the proxy job. This exercises that feature and utilizes it in a way for which it was designed.

Usage: run.sh [subcommand] [options] [--help]
|
|
|
|
Runs playwright tests in a Docker container against your shell's configured
|
|
Nomad target.
|
|
|
|
Subcommands:
|
|
test Run the tests (default behavior if no subcommand is provided). Options:
|
|
--no-install Don't run npm install because you've already done so.
|
|
|
|
shell Run a bash shell with the environment already set up. Maybe useful
|
|
for debugging.
|
|
|
|
proxy Deploy a reverse proxy. When the cluster is using mTLS, you will need
|
|
this so that we don't need to load a CA certificate into the browser.
|
|
This reverse proxy uses a self-signed cert. Will print a new NOMAD_ADDR
|
|
address for you to use for test runs.
|
|
|
|
ci For use in CI: runs the proxy, then tests, then stops the proxy.
|
|
|
|
Environment Variables:
|
|
NOMAD_ADDR Address of Nomad cluster or reverse proxy.
|
|
NOMAD_TOKEN Authentication token.
