The `nomad alloc status -verbose` command returns a 404 from CSI volumes
because the volume mount block in the task points back to the
`job.group.volume` block. So using the `Name` field to query is the "name" as
seen in the jobspec, and not the name of the volume that we need for querying.
Show both the job-specific name and the volume ID in the resulting output,
which clarifies the difference between the two fields and is more consistent
with the web UI.
This PR enables users of Nomad < 0.12 to upgrade to Nomad 0.12
and beyond. Nomad 0.12 introduced a network fingerprinter for
bridge networks, which is a contstraint checked for if bridge
network is being used. If users upgrade servers first as is
recommended, suddenly no clients running older versions of Nomad
will satisfy the bridge network resource constraint. Instead,
this change only enforces the constraint if the Nomad client
version is also >= 0.12.
Closes#8423
This PR adds the ability to set HTTP headers when downloading
an artifact from an `http` or `https` resource.
The implementation in `go-getter` is such that a new `HTTPGetter`
must be created for each artifact that sets headers (as opposed
to conveniently setting headers per-request). This PR maintains
the memoization of the default Getter objects, creating new ones
only for artifacts where headers are set.
Closes#9306
Avoids setting the node version in the release Dockerfile, by using
an alias. This allows us to update the node version in one file only.

Assert that deregistering a volume works without errors following a volume
reap. Use CLI helpers where feasible to exercise CSI command line. Dump plugin
allocation logs on deregistration failures for debugging purposes.
The HCL2 parser needs to apply special parsing tweaks so it can parse
the task config the same way as HCL1. Particularly, it needs to
reinterprets `map[string]interface{}` fields and blocks that appear when
attributes are expected.
This commit restricts the special casing to the Job fields, and ignore
`variables` and `locals` block.
* operator debug - add client node filtering arguments
* add WaitForClient helper function
* use RPC in WaitForClient to avoid unnecessary imports
* guard against nil values
* move initialization up and shorten test duration
* cleanup nodeLookupFailCount logic
* only display max node notice if we actually tried to capture nodes
Update the default value for `client.bridge_network_subnet` in docs
to match the new value from 99742f2665. Was `172.26.66.0/23`, is
now `172.26.64.0/20`.
Fixes#9316
Previously, connect sidecars would be re-registered with consul every cycle
of Nomad's reconciliation loop around Consul service registrations. This is
because part of the comparison used `reflect.DeepEqual` on []string objects,
which returns false when one object is `[]string{}` and the other is `[]string{}(nil)`.
Unforunately, this was always the case, and every Connect sidecar service
would be re-registered on every iteration, which happens every 30 seconds.
When raw_exec is configured with [`no_cgroups`](https://www.nomadproject.io/docs/drivers/raw_exec#no_cgroups), raw_exec shouldn't attempt to create a cgroup.
Prior to this change, we accidentally always required freezer cgroup to do stats PID tracking. We already have the proper fallback in place for metrics, so only need to ensure that we don't create a cgroup for the task.
