* docs: dispatch_payload docs had some weirdness
Docs said "Examples" when there was only 1 example. Not sure what the
floating "to" in the description was for.
* docs: missing a heading level on jobs api docs
The job evaluate endpoint creates a new evaluation for the job which is
a write operation. This change modifies the necessary capability from
`read-job` to `submit-job` to better reflect this.
* docs: add dynamic node metadata api docs
Also update all paths in the client API docs to explicitly state the
`/v1/` prefix. We're inconsistent about that, but I think it's better to
display the full path than to only show the fragment. If we ever do a
`/v2/` whether or not we explicitly state `/v1/` in our docs won't be
our greatest concern.
* docs: add task-api docs
Add `identity` jobspec block to expose workload identity tokens to tasks.

The ACL token decoding was not correctly handling time duration
syntax such as "1h" which forced people to use the nanosecond
representation via the HTTP API.
The change adds an unmarshal function which allows this syntax to
be used, along with other styles correctly.
Add a new `Eval.Count` RPC and associated HTTP API endpoints. This API is
designed to support interactive use in the `nomad eval delete` command to get a
count of evals expected to be deleted before doing so.
The state store operations to do this sort of thing are somewhat expensive, but
it's cheaper than serializing a big list of evals to JSON. Note that although it
seems like this could be done as an extra parameter and response field on
`Eval.List`, having it as its own endpoint avoids having to change the response
body shape and lets us avoid handling the legacy filter params supported by
`Eval.List`.

This changes adds ACL role creation and deletion to the event
stream. It is exposed as a single topic with two types; the filter
is primarily the role ID but also includes the role name.
While conducting this work it was also discovered that the events
stream has its own ACL resolution logic. This did not account for
ACL tokens which included role links, or tokens with expiry times.
ACL role links are now resolved to their policies and tokens are
checked for expiry correctly.
A Nomad user reported problems with CSI volumes associated with failed
allocations, where the Nomad server did not send a controller unpublish RPC.
The controller unpublish is skipped if other non-terminal allocations on the
same node claim the volume. The check has a bug where the allocation belonging
to the claim being freed was included in the check incorrectly. During a normal
allocation stop for job stop or a new version of the job, the allocation is
terminal. But allocations that fail are not yet marked terminal at the point in
time when the client sends the unpublish RPC to the server.
For CSI plugins that support controller attach/detach, this means that the
controller will not be able to detach the volume from the allocation's host and
the replacement claim will fail until a GC is run. This changeset fixes the
conditional so that the claim's own allocation is not included, and makes the
logic easier to read. Include a test case covering this path.
Also includes two minor extra bugfixes:
* Entities we get from the state store should always be copied before
altering. Ensure that we copy the volume in the top-level unpublish workflow
before handing off to the steps.
* The list stub object for volumes in `nomad/structs` did not match the stub
object in `api`. The `api` package also did not include the current
readers/writers fields that are expected by the UI. True up the two objects and
add the previously undocumented fields to the docs.
The ACL command docs are now found within a sub-dir like the
operator command docs. Updates to the ACL token commands to
accommodate token expiry have also been added.
The ACL API docs are now found within a sub-dir like the operator
API docs. The ACL docs now include the ACL roles endpoint as well
as updated ACL token endpoints for token expiration.
The configuration section is also updated to accommodate the new
ACL and server parameters for the new ACL features.
* allocrunner: handle lifecycle when all tasks die
When all tasks die the Coordinator must transition to its terminal
state, coordinatorStatePoststop, to unblock poststop tasks. Since this
could happen at any time (for example, a prestart task dies), all states
must be able to transition to this terminal state.
* allocrunner: implement different alloc restarts
Add a new alloc restart mode where all tasks are restarted, even if they
have already exited. Also unifies the alloc restart logic to use the
implementation that restarts tasks concurrently and ignores
ErrTaskNotRunning errors since those are expected when restarting the
allocation.
* allocrunner: allow tasks to run again
Prevent the task runner Run() method from exiting to allow a dead task
to run again. When the task runner is signaled to restart, the function
will jump back to the MAIN loop and run it again.
The task runner determines if a task needs to run again based on two new
task events that were added to differentiate between a request to
restart a specific task, the tasks that are currently running, or all
tasks that have already run.
* api/cli: add support for all tasks alloc restart
Implement the new -all-tasks alloc restart CLI flag and its API
counterpar, AllTasks. The client endpoint calls the appropriate restart
method from the allocrunner depending on the restart parameters used.
* test: fix tasklifecycle Coordinator test
* allocrunner: kill taskrunners if all tasks are dead
When all non-poststop tasks are dead we need to kill the taskrunners so
we don't leak their goroutines, which are blocked in the alloc restart
loop. This also ensures the allocrunner exits on its own.
* taskrunner: fix tests that waited on WaitCh
Now that "dead" tasks may run again, the taskrunner Run() method will
not return when the task finishes running, so tests must wait for the
task state to be "dead" instead of using the WaitCh, since it won't be
closed until the taskrunner is killed.
* tests: add tests for all tasks alloc restart
* changelog: add entry for #14127
* taskrunner: fix restore logic.
The first implementation of the task runner restore process relied on
server data (`tr.Alloc().TerminalStatus()`) which may not be available
to the client at the time of restore.
It also had the incorrect code path. When restoring a dead task the
driver handle always needs to be clear cleanly using `clearDriverHandle`
otherwise, after exiting the MAIN loop, the task may be killed by
`tr.handleKill`.
The fix is to store the state of the Run() loop in the task runner local
client state: if the task runner ever exits this loop cleanly (not with
a shutdown) it will never be able to run again. So if the Run() loops
starts with this local state flag set, it must exit early.
This local state flag is also being checked on task restart requests. If
the task is "dead" and its Run() loop is not active it will never be
able to run again.
* address code review requests
* apply more code review changes
* taskrunner: add different Restart modes
Using the task event to differentiate between the allocrunner restart
methods proved to be confusing for developers to understand how it all
worked.
So instead of relying on the event type, this commit separated the logic
of restarting an taskRunner into two methods:
- `Restart` will retain the current behaviour and only will only restart
the task if it's currently running.
- `ForceRestart` is the new method where a `dead` task is allowed to
restart if its `Run()` method is still active. Callers will need to
restart the allocRunner taskCoordinator to make sure it will allow the
task to run again.

This PR changes the behavior of 'nomad job validate' to forward the
request to the nomad leader, rather than responding from any server.
This is because we need the leader when validating Vault tokens, since
the leader is the only server with an active vault client.
Move the secure variables quota enforcement calls into the state store to ensure
quota checks are atomic with quota updates (in the same transaction).
Switch to a machine-size int instead of a uint64 for quota tracking. The
ENT-side quota spec is described as int, and negative values have a meaning as
"not permitted at all". Using the same type for tracking will make it easier to
the math around checks, and uint64 is infeasibly large anyways.
Add secure vars to quota HTTP API and CLI outputs and API docs.
* core: allow pause/un-pause of eval broker on region leader.
* agent: add ability to pause eval broker via scheduler config.
* cli: add operator scheduler commands to interact with config.
* api: add ability to pause eval broker via scheduler config
* e2e: add operator scheduler test for eval broker pause.
* docs: include new opertor scheduler CLI and pause eval API info.
This PR adds the 'choose' query parameter to the '/v1/service/<service>' endpoint.
The value of 'choose' is in the form '<number>|<key>', number is the number
of desired services and key is a value unique but consistent to the requester
(e.g. allocID).
Folks aren't really expected to use this API directly, but rather through consul-template
which will soon be getting a new helper function making use of this query parameter.
Example,
curl 'localhost:4646/v1/service/redis?choose=2|abc123'
Note: consul-templte v0.29.1 includes the necessary nomadServices functionality.
