Deployments should wait until kicked off by `Job.Register` so that we can
assert that all regions have a scheduled deployment before starting any
region. This changeset includes the OSS fixes to support the ENT work.
`IsMultiregionStarter` has no more callers in OSS, so remove it here.
The call to render the output diff swapped the `diff` and `verbose` bool
parameters, resulting in dropping the diff output in multi-region plans but
not single-region plans.
* ar: support opting into binding host ports to default network IP
* fix config plumbing
* plumb node address into network resource
* struct: only handle network resource upgrade path once
* made api.Scaling.Max a pointer, so we can detect (and complain) when it is neglected
* added checks to HCL parsing that it is present
* when Scaling.Max is absent/invalid, don't return extraneous error messages during validation
* tweak to multiregion handling to ensure that the count is valid on the interpolated regional jobs
resolves#8355
* command/agent/host: collect host data, multi platform
* nomad/structs/structs: new HostDataRequest/Response
* client/agent_endpoint: add RPC endpoint
* command/agent/agent_endpoint: add Host
* api/agent: add the Host endpoint
* nomad/client_agent_endpoint: add Agent Host with forwarding
* nomad/client_agent_endpoint: use findClientConn
This changes forwardMonitorClient and forwardProfileClient to use
findClientConn, which was cribbed from the common parts of those
funcs.
* command/debug: call agent hosts
* command/agent/host: eliminate calling external programs
The `nomad volume deregister` command currently returns an error if the volume
has any claims, but in cases where the claims can't be dropped because of
plugin errors, providing a `-force` flag gives the operator an escape hatch.
If the volume has no allocations or if they are all terminal, this flag
deletes the volume from the state store, immediately and implicitly dropping
all claims without further CSI RPCs. Note that this will not also
unmount/detach the volume, which we'll make the responsibility of a separate
`nomad volume detach` command.
* command/debug: build a local archive of debug data
* command/debug: query consul and vault directly
* command/debug: include pprof CPUProfile Trace and goroutine
* command/debug: trap signals and close the monitor requests
Having an active check in the sample job causes issues with testing
deployments in environments that are not integrated with Consul. This
negatively impacts some of the getting-started experiences. Commenting
out the check allows deployments to proceed successfully but leaves it
in the sample job for convenience.
Made a drive-by fix to all of the URLs in the jobfile
Add a scatter-gather for multiregion job plans. Each region's servers
interpolate the plan locally in `Job.Plan` but don't distribute the plan as
done in `Job.Run`.
Note that it's not possible to return a usable modify index from a multiregion
plan for use with `-check-index`. Even if we were to force the modify index to
be the same at the start of `Job.Run` the index immediately drifts during each
region's deployments, depending on events local to each region. So we omit
this section of a multiregion plan.
Adds a `-global` flag for stopping multiregion jobs in all regions at
once. Warn the user if they attempt to stop a multiregion job in a single
region.
This PR adds the capability of running Connect Native Tasks on Nomad,
particularly when TLS and ACLs are enabled on Consul.
The `connect` stanza now includes a `native` parameter, which can be
set to the name of task that backs the Connect Native Consul service.
There is a new Client configuration parameter for the `consul` stanza
called `share_ssl`. Like `allow_unauthenticated` the default value is
true, but recommended to be disabled in production environments. When
enabled, the Nomad Client's Consul TLS information is shared with
Connect Native tasks through the normal Consul environment variables.
This does NOT include auth or token information.
If Consul ACLs are enabled, Service Identity Tokens are automatically
and injected into the Connect Native task through the CONSUL_HTTP_TOKEN
environment variable.
Any of the automatically set environment variables can be overridden by
the Connect Native task using the `env` stanza.
Fixes#6083
Integration points for multiregion jobs to be registered in the enterprise
version of Nomad:
* hook in `Job.Register` for enterprise to send job to peer regions
* remove monitoring from `nomad job run` and `nomad job stop` for multiregion jobs
