In addition to this computation being wasteful, it introduces a bug
where the allocation on a stats tracker can update twice in one render,
which isn't allowed in Glimmer (ironically, Glimmmer's lack of
auto-memoization introduced the issue).
- Sorting must be done on copies to preserve orders.
- Indices should be reversed since rendering is also reversed (the back
layer (the tallest) is rendered first to create the stacking effect).
This leverages the existing pre-processing being done in the
allocation-stats-tracker to also create additive percentages relative to
the allocation resources vs. the task resources.
This can then be used in a chart to create a stacked area representation
of consumption.
This binds a function to a target before passing it along to another
component. It's normal to expect to get to use `this` within functions
on components and controllers, but (sans actions) that doesn't happen
automatically.
Currently, PrimaryMetric is already overloaded on multiple dimensions:
metric and resource type.
This refactor will use multiple components as a form of control flow
instead spidering conditionals, which are only getting worse as the
charts for each resource type diverge.
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.
Create a convenience command for generating example CSI volume specifications,
similar to the existing `nomad job init` or `nomad quota init` commands.
* 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
We've only ever had 1 API version, and we've broken backward
compatibility extremely rarely. Nothing changed about this with the
release of 1.0, let's just remove these sentences and save everybody
some reading.
Volume IDs are not UUIDs, so truncating them to the short ID isn't really
necessary and makes for especially awkward UX when per-alloc volumes are in
use.
The terminology here is a bit tricky. Technically Kuberbetes deprecated
their Docker *runtime* support but can still run Docker images. Sadly in
a lot of people's minds "Docker" and "containers" are nearly synonymous.
I think "Linux containers" is a more accurate characterization of
Kubernetes focus than "Docker" at this point.
Fixes#10120
When multiple CSI volumes are requested, the feasibility check could return
early for read/write volumes with free claims, even if a later volume in the
request was not feasible for any other reason (including not existing at
all). This can result in random failure to fail feasibility checking,
depending on how the map of volumes was being ordered at runtime.
Remove the early return from the feasibility check. Add a test to verify that
missing volumes in the map will cause a failure; this test will not catch a
regression every test run because of the random map ordering, but any failure
will be caught over the course of several CI runs.
The expose handler hook must handle if the submitted job is invalid. Without this validation, the rpc handler panics on invalid input.
