Remove the step to automatically backport `backport/website` PRs to the
latest release. This will be done manually by adding the proper tags.
Also use squash backports to match the pattern we use for `main`.
During the release there are several files that need to be modified:
- .release/ci.hcl: the notification channel needs to be updated to a
channel with greater team visibility during the release.
- version/version.go: the Version and VersionPrerelease variables
need to be set so they match the release version.
After the release these files need to be reverted.
For GA releases the following additional changes also need to happen:
- version/version.go: the Version variable needs to be bumped to the
next version number.
- GNUMakefile: the LAST_RELEASE variable needs to be set to the
version that was just released.
Since the release process will commit file changes to the branch being
used for the release, it should _never_ run on main, so the first step
is now to protect against that.
It also adds a validation to make the user input version is correct.
After looking at the different release options and steps I noticed that
automatic CHANGELOG generation is actually the exception, so it would be
better to have the default to be false.

This PR modifies raw_exec and exec to ensure the cgroup for a task
they are driving still exists during a task restart. These drivers
have the same bug but with different root cause.
For raw_exec, we were removing the cgroup in 2 places - the cpuset
manager, and in the unix containment implementation (the thing that
uses freezer cgroup to clean house). During a task restart, the
containment would remove the cgroup, and when the task runner hooks
went to start again would block on waiting for the cgroup to exist,
which will never happen, because it gets created by the cpuset manager
which only runs as an alloc pre-start hook. The fix here is to simply
not delete the cgroup in the containment implementation; killing the
PIDs is enough. The removal happens in the cpuset manager later anyway.
For exec, it's the same idea, except DestroyTask is called on task
failure, which in turn calls into libcontainer, which in turn deletes
the cgroup. In this case we do not have control over the deletion of
the cgroup, so instead we hack the cgroup back into life after the
call to DestroyTask.
All of this only applies to cgroups v2.
In #12324 we made it so that plugins wait until the node drain is
complete, as we do for system jobs. But we neglected to mark the node
drain as complete once only plugins (or system jobs) remaining, which
means that the node drain is left in a draining state until the
`deadline` time expires. This was incorrectly documented as expected
behavior in #12324.
notably:
- name of the compiled binary is 'nomad-device-nvidia', not 'nvidia-gpu'
- link to Nvidia docs for installing the container runtime toolkit
- list docker v19.03 as minimum version, to track with nvidia's new container runtime toolkit
The capacity fields for `create volume` set bounds on the resulting
size of the volume, but the ultimate size of the volume will be
determined by the storage provider (between the min and max). Clarify
this in the documentation and provide a suggestion for how to set a
exact size.

than 0.9. We have not supported 0.8.x in a very long time and in any
case the test has been marked to skip because the downloader doesn't
work.
Fixes#10200
**The bug**
A user reported receiving the following error when an alloc was placed
that needed to preempt existing allocs:
```
[ERROR] client.alloc_watcher: error querying previous alloc:
alloc_id=28... previous_alloc=8e... error="rpc error: alloc lookup
failed: index error: UUID must be 36 characters"
```
The previous alloc (8e) was already complete on the client. This is
possible if an alloc stops *after* the scheduling decision was made to
preempt it, but *before* the node running both allocations was able to
pull and start the preemptor. While that is hopefully a narrow window of
time, you can expect it to occur in high throughput batch scheduling
heavy systems.
However the RPC error made no sense! `previous_alloc` in the logs was a
valid 36 character UUID!
**The fix**
The fix is:
```
- prevAllocID: c.Alloc.PreviousAllocation,
+ prevAllocID: watchedAllocID,
```
The alloc watcher new func used for preemption improperly referenced
Alloc.PreviousAllocation instead of the passed in watchedAllocID. When
multiple allocs are preempted, a watcher is created for each with
watchedAllocID set properly by the caller. In this case
Alloc.PreviousAllocation="" -- which is where the `UUID must be 36 characters`
error was coming from! Sadly we were properly referencing
watchedAllocID in the log, so it made the error make no sense!
**The repro**
I was able to reproduce this with a dev agent with [preemption enabled](https://gist.github.com/schmichael/53f79cbd898afdfab76865ad8c7fc6a0#file-preempt-hcl)
and [lowered limits](https://gist.github.com/schmichael/53f79cbd898afdfab76865ad8c7fc6a0#file-limits-hcl)
for ease of repro.
First I started a [low priority count 3 job](https://gist.github.com/schmichael/53f79cbd898afdfab76865ad8c7fc6a0#file-preempt-lo-nomad),
then a [high priority job](https://gist.github.com/schmichael/53f79cbd898afdfab76865ad8c7fc6a0#file-preempt-hi-nomad)
that evicts 2 low priority jobs. Everything worked as expected.
However if I force it to use the [remotePrevAlloc implementation](https://github.com/hashicorp/nomad/blob/v1.3.0-beta.1/client/allocwatcher/alloc_watcher.go#L147),
it reproduces the bug because the watcher references PreviousAllocation
instead of watchedAllocID.
We moved off the old provisioning process for nightly E2E to one driven
entirely by Terraform quite a while back now. We're in the slow
process of removing the framework code for this test-by-test, but this
chunk of code no longer has any callers.
We enforce exactly one plugin supervisor loop by checking whether
`running` is set and returning early. This works but is fairly
subtle. It can briefly result in two goroutines where one quickly
exits before doing any work. Clarify the intent by using
`sync.Once`. The goroutine we've spawned only exits when the entire
task runner is being torn down, and not when the task driver restarts
the workload, so it should never be re-run.
* docs: update json jobs docs
Did you know that Nomad has not 1 but 2 JSON formats for jobs? 2½ if you
want to acknowledge that sometimes our JSON job representations have a
Job top-level wrapper and sometimes do not.
The 2½ formats are:
```
1. HCL JSON
2. Input API JSON (top-level Job field)
2.5. Output API JSON (lacks top-level Job field)
```
`#2` is what our docs consider our API JSON. `#2.5` seems to be an
accident of history we can't fix with breaking API compatibility.
`#1` is an even more interesting accident of history: the `jobspec2`
package automatically detects if the input to Parse is JSON and switches
to a JSON parser. This behavior is undocumented, the format is
unspecified, and there is no official HashiCorp tooling to produce this
JSON from HCL. The plot thickens when you discover popular third party
tools like hcl2json.com and https://github.com/tmccombs/hcl2json seem to
produce JSON that `nomad run` accepts!
Since we have no telemetry around whether or not anyone passes HCL JSON
to `nomad run`, and people don't file bugs around features that Just
Work, I'm choosing to leave that code path in place and *acknowledged
but not suggested* in documentation.
See https://github.com/hashicorp/hcl/issues/498 for a more comprehensive
discussion of what officially supporting HCL JSON in Nomad would look
like.
(I also added some of the missing fields to the (Input API flavor) JSON
Job documentation, but it still needs a lot of work to be
comprehensive.)

The task runner hook `Prestart` response object includes a `Done`
field that's intended to tell the client not to run the hook
again. The plugin supervisor creates mount points for the task during
prestart and saves these mounts in the hook resources. But if a client
restarts the hook resources will not be populated. If the plugin task
restarts at any time after the client restarts, it will fail to have
the correct mounts and crash loop until restart attempts run out.
Fix this by not returning `Done` in the response, just as we do for
the `volume_mount_hook`.
