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.
This PR enables job submitters to use interpolation in the connect
block of jobs making use of consul connect. Before, only the name of
the connect service would be interpolated, and only for a few select
identifiers related to the job itself (#6853). Now, all connect fields
can be interpolated using the full spectrum of runtime parameters.
Note that the service name is interpolated at job-submission time,
and cannot make use of values known only at runtime.

Previously, every Envoy Connect sidecar would spawn as many worker
threads as logical CPU cores. That is Envoy's default behavior when
`--concurrency` is not explicitly set. Nomad now sets the concurrency
flag to 1, which is sensible for the default cpu = 250 Mhz resources
allocated for sidecar proxies. The concurrency value can be configured
in Client configuration by setting `meta.connect.proxy_concurrency`.

Before, upstreams could only be defined using the default datacenter.
Now, the `datacenter` field can be set in a connect upstream definition,
informing consul of the desire for an instance of the upstream service
in the specified datacenter. The field is optional and continues to
default to the local datacenter.
Closes#8964
When making updates to CSI plugins, the state store methods that have open
write transactions were querying the state store using the same methods used
by the CSI RPC endpoint, but these method creates their own top-level read
transactions. During concurrent plugin updates (as happens when a plugin job
is stopped), this can cause write skew in the plugin counts.
* Refactor the CSIPlugin query methods to have an implementation method that
accepts a transaction, which can be called with either a read txn or a write
txn.
* Refactor the CSIVolume query methods to have an implementation method that
accepts a transaction, which can be called with either a read txn or a write
txn.
* CSI volumes need to be "denormalized" with their plugins and (optionally)
allocations. Read-only RPC endpoints should take a snapshot so that we can
make multiple state store method calls with a consistent view.
The CSIVolume struct "denormalizes" allocations when it's first queried from
the state store. The CSIVolumeByID method on the state store copies the volume
before denormalizing so that we don't end up with unexpected changes. The
copying has some subtle bugs that meant that Allocations (as well as
Topologies and MountOptions) were not getting copied when expected.
Also, ensure we never write allocations attached to volumes to the state store
during claims.
This PR adds the ability to set HTTP headers when downloading
an artifact from an `http` or `https` resource.
The implementation in `go-getter` is such that a new `HTTPGetter`
must be created for each artifact that sets headers (as opposed
to conveniently setting headers per-request). This PR maintains
the memoization of the default Getter objects, creating new ones
only for artifacts where headers are set.
Closes#9306
The unpublish workflow requires that we know the mode (RW vs RO) if we want to
unpublish the node. Update the hook and the Unpublish RPC so that we mark the
claim for release in a new state but leave the mode alone. This fixes a bug
where RO claims were failing node unpublish.
The core job GC doesn't know the mode, but we don't need it for that workflow,
so add a mode specifically for GC; the volumewatcher uses this as a sentinel
to check whether claims (with their specific RW vs RO modes) need to be claimed.
