on Linux systems this is derived from the configure cpuset cgroup parent (defaults to /nomad)
for non Linux systems and Linux systems where cgroups are not enabled, the client defaults to using all cores
Consul allows specifying the HTTP body to send in a health check. Nomad
uses Consul for health checking so this just plumbs the value through to
where the Consul API is called.
There is no validation that `body` is not used with an incompatible
check method like GET.
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 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.
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.
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.
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.
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.
This commit updates the API to pass the MemoryMaxMB field, and the CLI to show
the max set for the task.
Also, start parsing the MemoryMaxMB in hcl2, as it's set by tags.
A sample CLI output; note the additional `Max: ` for "task":
```
$ nomad alloc status 96fbeb0b
ID = 96fbeb0b-a0b3-aa95-62bf-b8a39492fd5c

Task "cgroup-fetcher" is "running"

The OTT feature relies on having a query parameter for a one-time token which
gets handled by the UI. We need to make sure that query param is preserved
when redirecting from the root URL to the `/ui/` URI.
node drain: use msgtype on txn so that events are emitted
wip: encoding extension to add Node.Drain field back to API responses
new approach for hiding Node.SecretID in the API, using `json` tag
documented this approach in the contributing guide
refactored the JSON handlers with extensions
modified event stream encoding to use the go-msgpack encoders with the extensions
Add a `PerAlloc` field to volume requests that directs the scheduler to test
feasibility for volumes with a source ID that includes the allocation index
suffix (ex. `[0]`), rather than the exact source ID.
Read the `PerAlloc` field when making the volume claim at the client to
determine if the allocation index suffix (ex. `[0]`) should be added to the
volume source ID.
Callers of `CSIVolumeByID` are generally assuming they should receive a single
volume. This potentially results in feasibility checking being performed
against the wrong volume if a volume's ID is a prefix substring of other
volume (for example: "test" and "testing").
Removing the incorrect prefix matching from `CSIVolumeByID` breaks prefix
matching in the command line client. Add the required elements for prefix
matching to the commands and API.
* Fixup uses of `sanity`
* Remove unnecessary comments.
These checks are better explained by earlier comments about
the context of the test. Per @tgross, moved the tests together
to better reinforce the overall shared context.
* Update nomad/fsm_test.go
If the user has disabled Prometheus metrics and a request is
sent to the metrics endpoint requesting Prometheus formatted
metrics, then the request should fail.
This PR fixes a bug where sidecar services would be re-registered into Consul every ~30
seconds, caused by the parent service having its tags field set and the sidecar_service
tags unset. Nomad would directly compare the tags between its copy of the sidecar service
definition and the tags of the sidecar service reported by Consul. This does not work,
because Consul will under-the-hood set the sidecar service tags to inherit the parent
service tags if the sidecar service tags are unset. The comparison then done by Nomad
would not match, if the parent sidecar tags are set.
Fixes#10025
