If Docker auth helpers are used but aith fails or the image isn't found, we
hard fail the task. Users may set `auth_soft_fail` to fallback to the public
Docker Hub on a per-job basis. But users that mix public and private images
have to set `auth_soft_fail=true` for every job using a public image if Docker
auth helpers are used.
* Remove Managed Sinks from Nomad
Managed Sinks were a beta feature in Nomad 1.0-beta2. During the beta
period it was determined that this was not a scalable approach to
support community and third party sinks.
* update comment
* changelog
Before, upstreams could only be defined using the default datacenter.
Now, the `datacenter` field can be set in a connect upstream definition,
informing consul of the desire for an instance of the upstream service
in the specified datacenter. The field is optional and continues to
default to the local datacenter.
Closes#8964
Add more detailed HCL2 docs, mostly lifted from Packer with tweaks for Nomad.
The function docs are basically verbatim taken from Packer with basic string substitutions. I commented out some for_each details as the examples are mostly driven towards Packer resources. I'll iterate on those with better Nomad examples.
The API is missing values for `ReadAllocs` and `WriteAllocs` fields, resulting
in allocation claims not being populated in the web UI. These fields mirror
the fields in `nomad/structs.CSIVolume`. Returning a separate list of stubs
for read and write would be ideal, but this can't be done without either
bloating the API response with repeated full `Allocation` data, or causing a
panic in previous versions of the CLI.
The `nomad/structs` fields are persisted with nil values and are populated
during RPC, so we'll do the same in the HTTP API and populate the `ReadAllocs`
and `WriteAllocs` fields with a map of allocation IDs, but with null
values. The web UI will then create its `ReadAllocations` and
`WriteAllocations` fields by mapping from those IDs to the values in
`Allocations`, instead of flattening the map into a list.
Only `change_mode = "restart"` will result in the template environment
variables being updated in the task. Clarify the behavior of the unsupported
options.
* `nomad operator keyring` was missing the general options section
* `nomad operator metrics` was missing a page in the docs entirely

Create a new "Operating Nomad" section of the docs where we can put reference
material for operators that doesn't quite fit in either configuration file /
command line documentation or a step-by-step Learn Guide. Pre-populate this
with the existing telemetry docs and some links out to the Learn Guide
sections.
* vault secrets named with `-` characters cannot be read by `consul-template`
due to limitations in golang's template rendering engine.
* environment variables are not modified in running tasks if
`change_mode.noop` is set.
The `nomad alloc logs` command does not remove terminal escape sequences for
color from the log outputs of a task. Clarify that the standard `-no-color`
flag, which does apply to Nomad's error responses from `nomad alloc logs`,
does not apply to the log output.
