In Nomad v0.12.0, the client added additional fingerprinting around the
presense of the bridge kernel module. The fingerprinter only checked in
`/proc/modules` which is a list of loaded modules. In some cases, the
bridge kernel module is builtin rather than dynamically loaded. The fix
for that case is in #8721. However we were still missing the case where
the bridge module is dynamically loaded, but not yet loaded during the
startup of the Nomad agent. In this case the fingerprinter would believe
the bridge module was unavailable when really it gets loaded on demand.
This PR now has the fingerprinter scan the kernel module dependency file,
which will contain an entry for the bridge module even if it is not yet
loaded.
In summary, the client now looks for the bridge kernel module in
- /proc/modules
- /lib/modules/<kernel>/modules.builtin
- /lib/modules/<kernel>/modules.dep
Closes#8423
Small changes to the Windows 2016 Packer build for debuggability of
provisioning:
* improve verbosity of powershell error handling
* remove unused "tools" installation
* use ssh communicator for Packer to improve Packer build times and eliminate
deprecated winrm remote access (unavailable from current macOS)
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.
* Get concrete types out of dynamic payload
wip
pull out value setting to func
* Add TestEventSTream_SetPayloadValue
Add more assertions
use alias type in unmarshalJSON to handle payload rawmessage
shorten unmarshal and remove anonymous wrap struct
* use map structure and helper functions to return concrete types
* ensure times are properly handled
* update test name
* put all decode logic in a single function

I believe there’s a typo where “workloads” was changed to “jobs” but the original word wasn’t removed. Or maybe it’s the other way around. But currently there is an orphaned one-word sentence.
