This changeset is part of the work to improve our E2E provisioning
process to allow our upgrade tests:
* Move more of the setup into the AMI image creation so it's a little
more obvious to provisioning config authors which bits are essential
to deploying a specific version of Nomad.
* Make the service file update do a systemd daemon-reload so that we
can update an already-running cluster with the same script we use to
deploy it initially.
Modernize Vault integration/e2e test a bit:
- Download from releases.hashicorp.com instead of using a hardcoded list
- Remove old unused make target e2e-test
- Use NOMAD_E2E env var instead of -integration flag
- Add a README
On my machine with ~250 Mbps internet it takes ~400s to download all
Vault binaries.
The system command includes gc and reconcile-summaries subcommands
which covers all currently available system API calls. The help
information is largely pulled from the current Nomad website API
documentation.
Passes in agent enable_debug config to nomad server and client configs.
This allows for rpc endpoints to have more granular control if they
should be enabled or not in combination with ACLs.
enable debug on client test
When multiple Connect-enabled task groups start on the same client
node, a race condition in the CNI plugins for creating iptables chains
causes one of the tasks to fail. We upstreamed a patch to CNI plugins
to make iptables chain creation idempotent.
This changeset updates end-to-end testing, development tooling, and
documentation to use 0.8.4 which includes our patch.
Now that alloc.Canonicalize() is called in all alloc sources in the
client (i.e. on state restore and RPC fetching), we no longer need to
check alloc.TaskResources.
alloc.AllocatedResources is always non-nil through alloc runner.
Though, early on, we check for alloc validity, so NewTaskRunner and
TaskEnv must still check. `TestClient_AddAllocError` test validates
that behavior.
This commit ensures that Alloc.AllocatedResources is properly populated
when read from persistence stores (namely Raft and client state store).
The alloc struct may have been written previously by an arbitrary old
version that may only populate Alloc.TaskResources.
In 0.10.2 (specifically 387b016) we added interpolation to group
service blocks and centralized the logic for task environment
interpolation. This wasn't also added to script checks, which caused a
regression where the IDs for script checks for services w/
interpolated fields (ex. the service name) didn't match the service ID
that was registered with Consul.
This changeset calls the same taskenv interpolation logic during
`script_check` configuration, and adds tests to reduce the risk of
future regressions by comparing the IDs of service hook and the check hook.
