The HCL1 parser did not respect connect.sidecar_task.resources if the
connect.sidecar_service block was not set (an optimiztion that no longer
makes sense with connect gateways).
Fixes#10899
Add a new hostname string parameter to the network block which
allows operators to specify the hostname of the network namespace.
Changing this causes a destructive update to the allocation and it
is omitted if empty from API responses. This parameter also supports
interpolation.
In order to have a hostname passed as a configuration param when
creating an allocation network, the CreateNetwork func of the
DriverNetworkManager interface needs to be updated. In order to
minimize the disruption of future changes, rather than add another
string func arg, the function now accepts a request struct along with
the allocID param. The struct has the hostname as a field.
The in-tree implementations of DriverNetworkManager.CreateNetwork
have been modified to account for the function signature change.
In updating for the change, the enhancement of adding hostnames to
network namespaces has also been added to the Docker driver, whilst
the default Linux manager does not current implement it.
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.
state store: call-out to generic update of job recommendations from job update method
recommendations API work, and http endpoint errors for OSS
support for scaling polices in task block of job spec
add query filters for ScalingPolicy list endpoint
command: nomad scaling policy list: added -job and -type
This eases adoption of the jobspec package by other projects (e.g. terraform nomad provider, Lavant). Either by consuming directy as a library (hopefully without having go mod import rest of nomad) or by copying the package without modification.
Ideally, this package will be published as an independent module. We aren't ready for that considering we'll be switching to HCLv2 "soon", but eitherway, this seems like a reasonable intermediate step if we choose to.
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 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.

Nomad doesn't do much besides pass the fields through to Consul.

update test to reflect new error
* 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

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
We have been using fatih/hclfmt which is long abandoned. Instead, switch
to HashiCorp's own hclfmt implementation. There are some trivial changes in
behavior around whitespace.
* jobspec, api: add stop_after_client_disconnect
* nomad/state/state_store: error message typo
* structs: alloc methods to support stop_after_client_disconnect
1. a global AllocStates to track status changes with timestamps. We
need this to track the time at which the alloc became lost
originally.
2. ShouldClientStop() and WaitClientStop() to actually do the math
* scheduler/reconcile_util: delayByStopAfterClientDisconnect
* scheduler/reconcile: use delayByStopAfterClientDisconnect
* scheduler/util: updateNonTerminalAllocsToLost comments
This was setup to only update allocs to lost if the DesiredStatus had
already been set by the scheduler. It seems like the intention was to
update the status from any non-terminal state, and not all lost allocs
have been marked stop or evict by now
* scheduler/testing: AssertEvalStatus just use require
* scheduler/generic_sched: don't create a blocked eval if delayed
* scheduler/generic_sched_test: several scheduling cases
Running `make dev` runs `hclfmt`, but this isn't checked as part of
CI. That makes it possible to merge un-formatted HCL and Nomad
jobspecs that later will make for dirty git staging areas when
developers pull master.
This changeset adds HCL linting to the `make check` target.
Before, the proxy stanza did not parse non-object fields
`local_service_port` and `local_service_address` from the
connect `proxy` stanza. This change fixes that.
Before, the submitted jobspec for sidecar_task would pass
through 2 key validation steps - once for the subset specific
to connect sidecar task definitions, and once again for the set
of normal task definition where the task would actually get
unmarshalled.
The valid keys for the normal task definition did not include
"name", which is supposed to be configurable for the sidecar
task. To fix this, just eliminate the double validation step,
and instead pass-in the correct set of keys to validate against
to the one generic task parser.
Fixes#7680
