The MaxQueryTime value used in QueryOptions.HasTimedOut() can be set to
an invalid value that would throw off how RPC requests are retried.
This fix uses the same logic that enforces the MaxQueryTime bounds in the
blockingRPC() call.

The ?resources=true query parameter includes resources in the object
stub listings. Specifically:
- For `/v1/nodes?resources=true` both the `NodeResources` and
`ReservedResources` field are included.
- For `/v1/allocations?resources=true` the `AllocatedResources` field is
included.
The ?task_states=false query parameter removes TaskStates from
/v1/allocations responses. (By default TaskStates are included.)

This Commit adds an /v1/events/stream endpoint to stream events from.
The stream framer has been updated to include a SendFull method which
does not fragment the data between multiple frames. This essentially
treats the stream framer as a envelope to adhere to the stream framer
interface in the UI.
If the `encode` query parameter is omitted events will be streamed as
newline delimted JSON.
As newer versions of Consul are released, the minimum version of Envoy
it supports as a sidecar proxy also gets bumped. Starting with the upcoming
Consul v1.9.X series, Envoy v1.11.X will no longer be supported. Current
versions of Nomad hardcode a version of Envoy v1.11.2 to be used as the
default implementation of Connect sidecar proxy.
This PR introduces a change such that each Nomad Client will query its
local Consul for a list of Envoy proxies that it supports (https://github.com/hashicorp/consul/pull/8545)
and then launch the Connect sidecar proxy task using the latest supported version
of Envoy. If the `SupportedProxies` API component is not available from
Consul, Nomad will fallback to the old version of Envoy supported by old
versions of Consul.
Setting the meta configuration option `meta.connect.sidecar_image` or
setting the `connect.sidecar_task` stanza will take precedence as is
the current behavior for sidecar proxies.
Setting the meta configuration option `meta.connect.gateway_image`
will take precedence as is the current behavior for connect gateways.
`meta.connect.sidecar_image` and `meta.connect.gateway_image` may make
use of the special `${NOMAD_envoy_version}` variable interpolation, which
resolves to the newest version of Envoy supported by the Consul agent.

Volumes using attachment mode `file-system` use the CSI filesystem API when
they're mounted, and can be passed mount options. But `block-device` mode
volumes don't have this option. When RPCs are made to plugins, we are silently
dropping the mount options we don't expect to see, but this results in a poor
operator experience when the mount options aren't honored. This changeset
makes passing mount options to a `block-device` volume a validation error.
Fixes a bug where CSI volumes with the `MULTI_NODE_MULTI_WRITER` access mode
were using the same logic as `MULTI_NODE_SINGLE_WRITER` to determine whether
the volume had writer claims available for scheduling.
Extends CSI claim endpoint test to exercise multi-reader and make sure `WriteFreeClaims`
is exercised for multi-writer in feasibility test.
This PR fixes a long standing bug where submitting jobs with changes
to connect services would not trigger updates as expected. Previously,
service blocks were not considered as sources of destructive updates
since they could be synced with consul non-destructively. With Connect,
task group services that have changes to their connect block or to
the service port should be destructive, since the network plumbing of
the alloc is going to need updating.
Fixes#8596#7991
Non-destructive half in #7192
Since CPU resources are usually a soft limit it is desirable to allow
setting it as low as possible to allow tasks to run only in "idle" time.
Setting it to 0 is still not allowed to avoid potential unintentional
side effects with allowing a zero value. While there may not be any side
effects this commit attempts to minimize risk by avoiding the issue.
This does *not* change the defaults.
When defining a script-check in a group-level service, Nomad needs to
know which task is associated with the check so that it can use the
correct task driver to execute the check.
This PR fixes two bugs:
1) validate service.task or service.check.task is configured
2) make service.check.task inherit service.task if it is itself unset
Fixes#8952
The current implementation measures RPC request timeout only against
config.RPCHoldTimeout, which is fine for non-blocking requests but will
almost surely be exceeded by long-poll requests that block for minutes
at a time.
This adds an HasTimedOut method on the RPCInfo interface that takes into
account whether the request is blocking, its maximum wait time, and the
RPCHoldTimeout.
Fix CSIMountOptions.Copy() and VolumeRequest.Copy() where they
accidentally returned a reference to self rather than a deep copy.
`&(*ref)` in Golang apparently equivalent to plain `&ref`.
The initial implementation of global job stop for MRD looped over all the
regions in the CLI for expedience. This changeset includes the OSS parts of
moving this into the RPC layer so that API consumers don't have to implement
this logic themselves.
Multiregion deployments use the `NomadTokenID` to allow the deploymentwatcher
to send RPCs between regions with the original submitter's ACL token. This ID
should be filtered from diffs so that it doesn't cause a difference for
purposes of job plans.
When consul.allow_unauthenticated is set to false, the job_endpoint hook validates
that a `-consul-token` is provided and validates the token against the privileges
inherent to a Consul Service Identity policy for all the Connect enabled services
defined in the job.
Before, the check was assuming the service was of type sidecar-proxy. This fixes the
check to use the type of the task so we can distinguish between the different connect
types.
This PR adds initial support for running Consul Connect Ingress Gateways (CIGs) in Nomad. These gateways are declared as part of a task group level service definition within the connect stanza.
```hcl
service {
connect {
gateway {
proxy {
// envoy proxy configuration
}
ingress {
// ingress-gateway configuration entry
}
}
}
}
```
A gateway can be run in `bridge` or `host` networking mode, with the caveat that host networking necessitates manually specifying the Envoy admin listener (which cannot be disabled) via the service port value.
Currently Envoy is the only supported gateway implementation in Consul, and Nomad only supports running Envoy as a gateway using the docker driver.
Aims to address #8294 and tangentially #8647
This change fixes a bug where lost/failed allocations are replaced by
allocations with the latest versions, even if the version hasn't been
promoted yet.
Now, when generating a plan for lost/failed allocations, the scheduler
first checks if the current deployment is in Canary stage, and if so, it
ensures that any lost/failed allocations is replaced one with the latest
promoted version instead.
This change adds the ability to set the fields `success_before_passing` and
`failures_before_critical` on Consul service check definitions. This is a
feature added to Consul v1.7.0 and later.
https://www.consul.io/docs/agent/checks#success-failures-before-passing-critical
Nomad doesn't do much besides pass the fields through to Consul.
Fixes#6913
When the client-side actions of a CSI client RPC succeed but we get
disconnected during the RPC or we fail to checkpoint the claim state, we want
to be able to retry the client RPC without getting blocked by the client-side
state (ex. mount points) already having been cleaned up in previous calls.
