This PR adds the common OSS changes for adding support for Consul Namespaces,
which is going to be a Nomad Enterprise feature. There is no new functionality
provided by this changeset and hopefully no new bugs.
When a volume is registered via `nomad volume register` and not via the
creation workflow, it may not have any of the capacity fields set (as they're
not used for registration). Handle this case without error, and let the
downstream RPCs handle the error case for `nomad volume create`.
This change disables using msgpack generated serializers in dev by
default.
In released binaries, we use code-generated msgpack serializers to
improve performance. However, in development, code generated
serializers are a pain. If a developer forgets to re-generate code, the
code generated gets out of sync with the go structs, and result into
subtle bugs where some values appear not to persist as expected.
The CI and release scripts will continue to use the msgpack
code-generation. Devs who want to test locally can set
`GO_TAGS=codegen_generated` as well.
In order to support new node RPCs, we need to fingerprint plugin capabilities
in more detail. This changeset mirrors recent work to fingerprint controller
capabilities, but is not yet in use by any Nomad RPC.
This adds UI support for receiving the one-time token passed via query parameter, as in #10134
and related PRs, and exchanging it for its corresponding secret ID. When this works, it’s mostly
invisible, with a brief flash of the OTT onscreen.
The authentication failure message now suggests the -authenticate flag.
When OTT exchange fails, it shows a whole-page error.
This includes a known UX shortcoming in that the OTT will not disappear from the URL when an
identifier is specified on the command line, like nomad ui -authenticate jobname. The goal is to
address that shortcoming in a forthcoming pull request.
If the docker engine is running on cgroup-v2 host, then RSS and Max
Usage doesn't get reported.
Using a heauristic here to avoid adding more API calls to the Docker
Engine to infer cgroups version. Also, opted to avoid coordinating stats
collection with fingerprinting, which adds concurrency complexities.
Add new commands for creating, deleting, and listing external storage
volumes. Includes HCL decoding update for volume spec so that we can humanize
capacity bytes input values.
The HTTP test to create CSI volumes depends on having a controller plugin to
talk to, but the test was using a node-only plugin, which allows it to
silently ignore the missing controller.
In order to support new controller RPCs, we need to fingerprint volume
capabilities in more detail and perform controller RPCs only when the specific
capability is present. This fixes a bug in Ceph support where the plugin can
only suport create/delete but we assume that it also supports attach/detach.
The CSI specification requires that we validate a list of `Capability` (access
mode + accessibility) when we create volume, but the existing volume
registration workflow incorrectly validates a single capability. The
specific capability required by a volume claim is checked at the time we make
the claim, so remove the check for `AttachmentMode`/`AcccessMode`.
This commit includes a new test client that allows overriding the RPC
protocols. Only the RPCs that are passed in are registered, which lets you
implement a mock RPC in the server tests. This commit includes an example of
this for the ClientCSI RPC server.
Note that unset proto fields for volume create should be nil. The CSI spec
handles empty fields and nil fields in the protobuf differently, which may
result in validation failures for creating volumes with no prior source (and
does in testing with the AWS EBS plugin). Refactor the `CreateVolumeRequest`
mapping to the protobuf in the plugin client to avoid this bug.
