Instead of creating recommendations for all the jobs used
across these tests, this creates a specific job with
a higher group count, which reduces the likelihood
of having no recommendations to 0.0001%.
It was incorrect to assume that each task group would always
have recommendations, since there’s a 1% chance that a task
won’t have a recommendation. (10% chance for CPU and memory.)
This uses the number of groups with recommendations instead.
This builds on filtering to allow the optimize page to show recommendations
for the active namespace vs all namespaces. If turning off the toggle causes
the summary from the active card to become excluded from the filtered list,
the active summary changes, as with the facets.
It also includes a fix for this bug:
https://github.com/hashicorp/nomad/pull/9294#pullrequestreview-527748994
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.
Plugin health for controllers should show "Node Only" in the UI only when both
conditions are true: controllers are not required, and no controllers have
registered themselves (0 expected controllers). This accounts for "monolith"
plugins which might register as both controllers and nodes but not necessarily
have `ControllerRequired = true` because they don't implement the Controller
RPC endpoints we need (this requirement was added in #7844)
This changeset includes the following fixes:
* Update the Plugins tab of the UI so that monolith plugins don't show "Node
Only" once they've registered.
* Add the missing "Node Only" logic to the Volumes tab of the UI.
This is mostly copied from the jobs list. One uncertainty
is what to do when changing a facet causes the currently-
active card to be excluded from the filtered list 🤔
Without this, visiting any job detail page on Nomad OSS would crash with
an error like this:
Error: Ember Data Request GET
/v1/recommendations?job=ping%F0%9F%A5%B3&namespace=default returned a
404 Payload (text/xml)
The problem was twofold.
1. The recommendation ability didn’t include anything about checking
whether the feature was present. This adds a request to
/v1/operator/license on application load to determine which features are
present and store them in the system service. The ability now looks for
'Dynamic Application Sizing' in that feature list.
2. Second, I didn’t check permissions at all in the job-fetching or job
detail templates.
This continues iteration on the DAS UI by adding the ability to directly
navigate to a recommendation summary by (namespaced) slug and a copy
button for the direct navigation link.
It includes a change to CopyButton allowing it to take a block that’s
rendered within the button.
It also changes some instances of multi-relationship traversal to use
in-summary attributes, such as summary.jobNamespace instead of
summary.job.namespace.name.
Before, we'd show a helpful error message when a task isn't running
instead of erroring in a generic way. Turns out when an alloc is
terminal but reachable, the filesystem is left behind so we were hiding
it.
Now it is always shown and in the event that something errors, it'll
either be generic, or--more commonly--a 404 of the allocation.
