This closes#9495. As detailed in there, the collection query GET
/v1/volumes?type=csi doesn’t return ReadAllocs and WriteAllocs, so the #
Allocs cell was always showing 0 upon first load because it was derived
from the lengths of those arrays. This uses the heretofore-ignored
CurrentReaders and CurrentWriters values to calculate the total instead.
The single-resource query GET /v1/volume/csi%2F:id doesn’t return
CurrentReaders and CurrentWriters that absence doesn’t override the
stored values when visiting an individual item.
Thanks to @apollo13 for reporting this and to @tgross for the API logs
and suggestion.
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.
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.
The job factory will now accept an array of resourceSpecs that is a shorthand
notation for memory, cpu, disk, and iops requirements.
These specs get passed down to task groups. The task group factory will
split the resource requirements near evenly (there is variance
threshold) across all expected tasks.
Allocations then construct task-resource objects based on the resources
from the matching task.
This partially addresses #7799.
Task state filesystems are contained within a subdirectory of their
parent allocation, so almost everything that existed for browsing task
state filesystems was applicable to browsing allocations, just without
the task name prepended to the path. I aimed to push this differential
handling into as few contained places as possible.
The tests also have significant overlap, so this includes an extracted
behavior to run the same tests for allocations and task states.
Closes#7197#7199
Note: Test coverage is limited to adapter and serializer unit tests. All
acceptance tests have been stubbed and all features have been manually
tested end-to-end.
This represents Phase 1 of #6993 which is the core workflow of CSI in
the UI. It includes a couple new pages for viewing all external volumes
as well as the allocations associated with each. It also updates
existing volume related views on job and allocation pages to handle both
Host Volumes and CSI Volumes.
This connects Xterm.js to a Nomad exec websocket so people
can interact on clients via live sessions. There are buttons on
job, allocation, task group, and task detail pages that open a
popup that lets them edit their shell command and start a
session.
More is to come, as recorded in issues.
This builds on API changes in #6017 and #6021 to conditionally turn off the
“Run Job” button based on the current token’s capabilities, or the capabilities
of the anonymous policy if no token is present.
If you try to visit the job-run route directly, it redirects to the job list.
This sets a default-but-query-configurable Faker seed in development,
via faker-seed. It also changes uses of Math.random to use Faker’s
randomness so auto-generated data remains stable in development.
I noticed while working on #6166 that some of the factory properties
that used Faker’s randomisation features are using their output
rather than a function that would call the randomiser. This means that
the randomisation happens once and the value is used for every model
generated by the factory. This wraps the randomiser calls in functions
so different models can have different values.
Protect against case where an alloc has no services and avoid
dereferencing null.
Here, we ensure that the model and test serializers mimic the API by
having nil TaskGroup.Services instead of an empty array.
