Our API client `delete` method doesn't include a request body, but accepts an
interface for the response. We were accidentally putting the request body into
the response, which doesn't get picked up in unit tests because we're not
reading the (always empty) response body anyways.
The plugin stub object does not include fine-grained capability checks, which
means `nomad volume status -verbose` will return ugly and verbose error
"Unimplemented" messages from the plugin if it does not support the CSI
`ListVolumes` RPC. Return a nicer error message from our RPC handler instead.
The HTTP router did not correctly route `/v1/volumes/external` without being
explicitly added to the top-level router. Break this out into its own request
handler.
If a plugin returns an error, we should continue at the outer scope to query
the next plugin, otherwise we just retry the plugin we got an error
on (potentially infinitely if it's an invalid request like an unsupported
plugin).
Add new `access_mode`/`attachment_mode` fields. Make it more clear which set
of fields belong to create vs register. Update the example spec that's
generated by `volume init`.
Registration of Nomad volumes previously allowed for a single volume
capability (access mode + attachment mode pair). The recent `volume create`
command requires that we pass a list of requested capabilities, but the
existing workflow for claiming volumes and attaching them on the client
assumed that the volume's single capability was correct and unchanging.
Add `AccessMode` and `AttachmentMode` to `CSIVolumeClaim`, use these fields to
set the initial claim value, and add backwards compatibility logic to handle
the existing volumes that already have claims without these fields.
Previously installing buf was left out of `make bootstrap` because it
had conflicts with the `tools/go.mod` file and dependencies used by
other tools. With Go 1.16 we eliminated that `go.mod` file, and can
now just install `buf` with `go install` like everything else.
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.
