The HTTP test to create CSI volumes depends on having a controller plugin to
talk to, but the test was using a node-only plugin, which allows it to
silently ignore the missing controller.
This commit includes a new test client that allows overriding the RPC
protocols. Only the RPCs that are passed in are registered, which lets you
implement a mock RPC in the server tests. This commit includes an example of
this for the ClientCSI RPC server.
This commit updates the API to pass the MemoryMaxMB field, and the CLI to show
the max set for the task.
Also, start parsing the MemoryMaxMB in hcl2, as it's set by tags.
A sample CLI output; note the additional `Max: ` for "task":
```
$ nomad alloc status 96fbeb0b
ID = 96fbeb0b-a0b3-aa95-62bf-b8a39492fd5c

The OTT feature relies on having a query parameter for a one-time token which
gets handled by the UI. We need to make sure that query param is preserved
when redirecting from the root URL to the `/ui/` URI.
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.
* 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
If the user has disabled Prometheus metrics and a request is
sent to the metrics endpoint requesting Prometheus formatted
metrics, then the request should fail.
This PR fixes a bug where sidecar services would be re-registered into Consul every ~30
seconds, caused by the parent service having its tags field set and the sidecar_service
tags unset. Nomad would directly compare the tags between its copy of the sidecar service
definition and the tags of the sidecar service reported by Consul. This does not work,
because Consul will under-the-hood set the sidecar service tags to inherit the parent
service tags if the sidecar service tags are unset. The comparison then done by Nomad
would not match, if the parent sidecar tags are set.
Fixes#10025
Allow for readiness type checks by configuring nomad to ignore warnings
or errors reported by a service check. This allows the deployment to
progress and while Consul handles introducing the sercive into a
resource pool once the check passes.
This PR implements Nomad built-in support for running Consul Connect
terminating gateways. Such a gateway can be used by services running
inside the service mesh to access "legacy" services running outside
the service mesh while still making use of Consul's service identity
based networking and ACL policies.
https://www.consul.io/docs/connect/gateways/terminating-gateway
These gateways are declared as part of a task group level service
definition within the connect stanza.
service {
connect {
gateway {
proxy {
// envoy proxy configuration
}
terminating {
// terminating-gateway configuration entry
}
}
}
}
Currently Envoy is the only supported gateway implementation in
Consul. The gateay task can be customized by configuring the
connect.sidecar_task block.
When the gateway.terminating field is set, Nomad will write/update
the Configuration Entry into Consul on job submission. Because CEs
are global in scope and there may be more than one Nomad cluster
communicating with Consul, there is an assumption that any terminating
gateway defined in Nomad for a particular service will be the same
among Nomad clusters.
Gateways require Consul 1.8.0+, checked by a node constraint.
Closes#9445
* Prevent Job Statuses from being calculated twice
https://github.com/hashicorp/nomad/pull/8435 introduced atomic eval
insertion iwth job (de-)registration. This change removes a now obsolete
guard which checked if the index was equal to the job.CreateIndex, which
would empty the status. Now that the job regisration eval insetion is
atomic with the registration this check is no longer necessary to set
the job statuses correctly.
* test to ensure only single job event for job register
* periodic e2e
* separate job update summary step
* fix updatejobstability to use copy instead of modified reference of job
* update envoygatewaybindaddresses copy to prevent job diff on null vs empty
* set ConsulGatewayBindAddress to empty map instead of nil
fix nil assertions for empty map
rm unnecessary guard
This removes modification of ops in methods that UpdateWorkload calls, keeping
them local to UpdateWorkload. It also includes some rewrites of checkRegs for
clarity.
Submitting a job with an ingress gateway in host networking mode
with an absent gateway.proxy block would cause the Nomad client
to panic on NPE.
The consul registration bits would assume the proxy stanza was
not nil, but it could be if the user does not supply any manually
configured envoy proxy settings.
Check the proxy field is not nil before using it.
Fixes#9669
https://github.com/hashicorp/nomad/pull/9608 introduced the use of the
built-in HTTP 429 response handler provided by go-connlimit. There is
concern though around plausible DOS attacks that need to be addressed,
so this PR reverts that functionality.
It keeps a fix in the tests around the use of an HTTPS enabled client
for when the server is listening on HTTPS. Previously, the tests would
fail deterministically with io.EOF because that's how the TLS server
terminates invalid connections.
Now, the result is much less deterministic. The state of the client
connection and the server socket depends on when the connection is
closed and how far along the handshake was.
