node drain: use msgtype on txn so that events are emitted
wip: encoding extension to add Node.Drain field back to API responses
new approach for hiding Node.SecretID in the API, using `json` tag
documented this approach in the contributing guide
refactored the JSON handlers with extensions
modified event stream encoding to use the go-msgpack encoders with the extensions
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
The expose handler hook must handle if the submitted job is invalid. Without this validation, the rpc handler panics on invalid input.

RPC endpoints for the user-driven APIs (`UpsertOneTimeToken` and
`ExchangeOneTimeToken`) and token expiration (`ExpireOneTimeTokens`).
Includes adding expiration to the periodic core GC job.
In a deployment with two groups (ex. A and B), if group A's canary becomes
healthy before group B's, the deadline for the overall deployment will be set
to that of group A. When the deployment is promoted, if group A is done it
will not contribute to the next deadline cutoff. Group B's old deadline will
be used instead, which will be in the past and immediately trigger a
deployment progress failure. Reset the progress deadline when the job is
promotion to avoid this bug, and to better conform with implicit user
expectations around how the progress deadline should interact with promotions.
This PR enables jobs configured with a custom sidecar_task to make
use of the `service.expose` feature for creating checks on services
in the service mesh. Before we would check that sidecar_task had not
been set (indicating that something other than envoy may be in use,
which would not support envoy's expose feature). However Consul has
not added support for anything other than envoy and probably never
will, so having the restriction in place seems like an unnecessary
hindrance. If Consul ever does support something other than Envoy,
they will likely find a way to provide the expose feature anyway.
Fixes#9854
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.
The details of host volume and CSI volume requests do not show up in `nomad
plan` outputs, although the updates are detected by the scheduler and result
in an update as expected.
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.

* 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
If the connect.proxy stanza is left unset, the connection timeout
value is not set but is assumed to be, and may cause a non-fatal NPE
on job submission.
* Throw away result of multierror.Append
When given a *multierror.Error, it is mutated, therefore the return
value is not needed.
* Simplify MergeMultierrorWarnings, use StringBuilder
* Hash.Write() never returns an error
* Remove error that was always nil
* Remove error from Resources.Add signature
When this was originally written it could return an error, but that was
refactored away, and callers of it as of today never handle the error.
* Throw away results of io.Copy during Bridge
* Handle errors when computing node class in test
In this change we'll properly return the error in the
CSIPluginTypeMonolith case (which is the type given in DeleteNode()),
and also return the error when the given ID is not found.
This was found via errcheck.

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
Add the ability to configure the Task used for Connect gateways,
similar to how sidecar Task can be configured.
The implementation here simply re-uses the sidecar_task stanza,
and now gets applied whether connect.sidecar_service or
connect.gateway is the thing being defined. In retrospect,
connect.sidecar_task could have been more generically named
like connect.task to make it a little more re-usable.
Closes#9474
Nomad v1.0.0 introduced a regression where the client configurations
for `connect.sidecar_image` and `connect.gateway_image` would be
ignored despite being set. This PR restores that functionality.
There was a missing layer of interpolation that needs to occur for
these parameters. Since Nomad 1.0 now supports dynamic envoy versioning
through the ${NOMAD_envoy_version} psuedo variable, we basically need
to first interpolate
${connect.sidecar_image} => envoyproxy/envoy:v${NOMAD_envoy_version}
then use Consul at runtime to resolve to a real image, e.g.
envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.16.0
Of course, if the version of Consul is too old to provide an envoy
version preference, we then need to know to fallback to the old
version of envoy that we used before.
envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.11.2@sha256:a7769160c9c1a55bb8d07a3b71ce5d64f72b1f665f10d81aa1581bc3cf850d09
Beyond that, we also need to continue to support jobs that set the
sidecar task themselves, e.g.
sidecar_task { config { image: "custom/envoy" } }
which itself could include teh pseudo envoy version variable.

Applying the default --concurrency for gateways was missed before.
Set the default Envoy concurrency to 1 for connect gateways. The
same override value meta.connect.proxy_concurrency applies.
