Previously, Nomad would fail to startup if the CPU fingerprinter could
not detect the cpu total compute (i.e. cores * mhz). This is common on
some EC2 instance types (graviton class), where the env_aws fingerprinter
will override the detected CPU performance with a more accurate value
anyway.
Instead of crashing on startup, have Nomad use a low default for available
cpu performance of 1000 ticks (e.g. 1 core * 1 GHz). This enables Nomad
to get past the useless cpu fingerprinting on those EC2 instances. The
crashing error message is now a log statement suggesting the setting of
cpu_total_compute in client config.
Fixes#7989
This PR enables job submitters to use interpolation in the connect
block of jobs making use of consul connect. Before, only the name of
the connect service would be interpolated, and only for a few select
identifiers related to the job itself (#6853). Now, all connect fields
can be interpolated using the full spectrum of runtime parameters.
Note that the service name is interpolated at job-submission time,
and cannot make use of values known only at runtime.
Fixes#7221
* docs: Remove 1.0 beta warning about HCL2.0 docs
* docs: multiregion is not beta anymore either
* docs: scaling isn't beta
* docs: neither is events api
* debug: refactor nodeclass test
* debug: add case to track down SIGSEGV on client to server Agent.Host RPC
* verify server to avoid panic on AgentHostRequest RPC call, fixes GH-9546
* simplify Agent.Host RPC lookup logic
Mainly note that block labels need to be string literals, and that decimals without a leading significant digits aren't acceptable anymore (e.g. .9 are required to be 0.9).
Dynamic blocks can be used here, but feels too much of a hack, or a hammer to highlight it here, specially given the error reporting and debugging isn't so straightforward. I'd advocate internally for relaxing the restriction and allowing expressions in block labels instead.

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.
This adds:
* a script for building and deploying the Ember UI and Storybook to
Vercel
* configuration for that deployment
* a header link to the UI to link to Storybook when built with
STORYBOOK_LINK=true
It also removes a file used to configure Netlify redirects.
The Netlify setup had two “sites”: nomad-storybook and nomad-ui. I
attempted to replicate that here but ran into some platform limitations
with Vercel: two “projects” cannot share the same root directory without
also sharing the same vercel.json that lets us specify configuration
such as the rewrite needed to handle deep linking into the Ember UI. I
tried having Storybook use /ui/storybook as the root directory (and
adding a symbolically-linked package.json to bypass Vercel’s refusal
to build without it) but that produced broken Storybook deployments.
This instead combines the two projects into one
(nomad-storybook-and-ui), defaults to forwarding / to /ui/, and
adds the header link to the UI to navigate to Storybook.
Rather than have a complex build script in the Vercel configuration UI,
this delegates to a script in the repository.
During testing we discovered old versions of Nomad and Consul seemed to
prevent Envoy from accepting new connections while the Nomad agent was
being upgraded.
