* remove outdated references to envchain in documentation
* add new host volume locations in userdata
* don't exit the entire script during provisioning, just return
The CLI helpers in the rescheduling test were intended for shared use, but
until some other tests were written we didn't want to waste time making them
generic. This changeset refactors them and adds some new helpers associated
with the node drain tests (under separate PR).
Volume requests can be either CSI or host volumes, so when displaying the CSI
volume info for `nomad node status -verbose` we need to filter out the host
volumes.
Allocation requests should target servers, which then can forward the
request to the appropriate clients.
Contacting clients directly is fragile and prune to failures: e.g.
clients maybe firewalled and not accessible from the API client, or have
some internal certificates not trusted by the API client.
FWIW, in contexts where we anticipate lots of traffic (e.g. logs, or
exec), the api package attempts contacting the client directly but then
fallsback to using the server. This approach seems excessive in these
simple GET/PUT requests.
Fixes#8894
In #7800, Nomad would automatically generate a port label for service
checks making use of the expose feature, if the port was not already
set. This change assumed the group network would be correctly defined
(as is checked in a validation hook later). If the group network was
not definied, a panic would occur on job submisssion. This change
re-uses the group network validation helper to make sure the network
is correctly definied before adding ports to it.
Fixes#8875
The rescheduling test workloads were created before we had Windows targets in
the E2E nightly run. When these were recently ported to the e2e framework they
were missing the constraint to Linux machines.
Also added a little extra time to polling to avoid some flakiness on the first
run, and a minor readability adjustment to the job names.
The change was intended to fix a case where a canary alloc may fail to
be rescheduled if all the other allocs fail as well (e.g. if all allocs
happen to be placed on a node that died). However, it introduced some
unintended side-effects.
Reverting the change for now and will investigate further.
Ports the rescheduling tests (which aren't running in CI) into the current
test framework so that they're run on nightly, and exercises the new CLI
helpers.
The E2E suite exercises the API, but not the CLI. This changeset adds a helper
function to send commands via a locally-built Nomad binary (which we'll need
to add to the E2E setup), and some helpers to parse the resulting structured
outputs in a way that tests can consume.
Copy Consul API's format: QueryOptions.WithContext(context) will now return
a new QueryOption whose HTTP requests will be canceled with the context
provided (and similar for WriteOptions)
