Add a new driver capability: RemoteTasks.
When a task is run by a driver with RemoteTasks set, its TaskHandle will
be propagated to the server in its allocation's TaskState. If the task
is replaced due to a down node or draining, its TaskHandle will be
propagated to its replacement allocation.
This allows tasks to be scheduled in remote systems whose lifecycles are
disconnected from the Nomad node's lifecycle.
See https://github.com/hashicorp/nomad-driver-ecs for an example ECS
remote task driver.
This PR adds e2e tests for Consul Namespaces for Nomad Enterprise
with Consul ACLs enabled.
Needed to add support for Consul ACL tokens with `namespace` and
`namespace_prefix` blocks, which Nomad parses and validates before
tossing the token. These bits will need to be picked back to OSS.
This PR fixes a bug where Nomad was more restrictive on Ingress Gateway Configuration
Entry definitions than Consul. Before, Nomad would not allow for declaring IGCEs with
http listeners with service name "*", which is a special feature allowable by Consul.
Note: to make http protocol work, a service-default must be defined setting the
protocol to http for each service.
Fixes: #9729
This PR adds job-submission validation that checks for the use of uppercase characters
in group and service names for services that make use of Consul Connect. This prevents
attempting to launch services that Consul will not validate correctly, which in turn
causes tasks to fail to launch in Nomad.
Underlying Consul issue: https://github.com/hashicorp/consul/issues/6765Closes#7581#10450
This PR wraps the use of the consul envoy bootstrap command in
an expoenential backoff closure, configured to timeout after 60
seconds. This is an increase over the current behavior of making
3 attempts over 6 seconds.
Should help with #10451
Add Namespace as a top-level field in `/v1/jobs` stub.
The `/v1/jobs` endpoint already includes the namespace under `JobSummary`, though the API is odd, as typically the job ID and Namespace are in the same level, and the oddity complicates the UI frontend development.
The downside of adding it is redundant field, that makes the response body a bit bigger, specially for clusters with large jobs. Though, it should compress nicely and I expect the overhead to be small to overall response size. The benefit of a cleaner and more consistent API seem worth it.
Fixes#10431
ParentID is an internal field that Nomad sets for dispatched or parameterized jobs. Job submitters should not be able to set it directly, as that messes up children tracking.
Fixes#10422 . It specifically stops the scheduler from honoring the ParentID. The reason failure and why the scheduler didn't schedule that job once it was created is very interesting and requires follow up with a more technical issue.
This fixes a regression in #10326, to handle unquoted unknown variables.
The HCL job may contain unquoted undefined variable references without ${...} wrapping, e.g. value = meta.node_class. In 1.0.4, this got parsed as value = "${meta.node_class}".
This code performs a scan to find the relevant ${ and }, and only tries to find the closest ones with whitespace as the only separator.
This fixes a bug affecting drain nodes, where allocs may fail to be
migrated if they belong to different namespaces but share the same job
name.
The reason is that the helper function that creates the migration evals
indexed the allocs by job ID without accounting for the namespaces.
When job ids clash, only an eval is created for one and the rest of the
allocs remain intact.
Fixes#10172
Add templating to `network-interface` option.
This PR also adds a fast-fail to in the case where an invalid interface is set or produced by the template
* add tests and check for valid interface
* Add documentation
* Incorporate suggestions from code review

Small change to pull in ent struct types in a switch
statement used by ent. They are benign in oss, this
is just to make sure OSS->ENT merges don't create a
diff.
This adds a Revert two-step button to the JobVersions component for
not-current versions, which redirects to the overview on success. It
checks the job version before and after reversion to mitigate the edge
case where reverting to an otherwise-identical version has no effect, as
discussed in #10337.
It uses existing facilities for handling other errors and disabling the
button when permissions are lacking.
Similar to a bugfix made for the services hook, we need to always
set the script checks hook, in case a task is initially launched
without script checks, but then updated to include script checks.
The scipt checks hook is the thing that handles that new registration.
(cherry-picked from ent without _ent things)
This is part 2/4 of e2e tests for Consul Namespaces. Took a
first pass at what the parameterized tests can look like, but
only on the ENT side for this PR. Will continue to refactor
in the next PRs.
Also fixes 2 bugs:
- Config Entries registered by Nomad Server on job registration
were not getting Namespace set
- Group level script checks were not getting Namespace set
Those changes will need to be copied back to Nomad OSS.
Nomad OSS + no ACLs (previously, needs refactor)
Nomad ENT + no ACLs (this)
Nomad OSS + ACLs (todo)
Nomad ENT + ALCs (todo)
