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
* docker: support group allocated ports
* docker: add new ports driver config to specify which group ports are mapped
* docker: update port mapping docs
The soundness guarantees of the CSI specification leave a little to be desired
in our ability to provide a 100% reliable automated solution for managing
volumes. This changeset provides a new command to bridge this gap by providing
the operator the ability to intervene.
The command doesn't take an allocation ID so that the operator doesn't have to
keep track of alloc IDs that may have been GC'd. Handle this case in the
unpublish RPC by sending the client RPC for all the terminal/nil allocs on the
selected node.
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.

Postrun hooks for allocation runners don't currently block the registration of
terminal health with the servers, which is what allows system jobs to be
drained. So draining nodes with jobs that claim CSI volumes requires the
`-ignore-system` job to ensure that the postrun hook for service jobs gets a
chance to execute.
The Nomad binary size has been detailed differently in places
and is subject to changing almost daily. We should therefore
remove this to avoid confusion and misrepresentation.

Also fixed the same typo in a test. Fixing the typo fixes the link, but
the link was still broken when running the website locally due to the
trailing slash. It would have worked in prod thanks to redirects, but
using the canonical URL seems ideal.
Not sure if this was meant to imply adding more schedulers to Nomad is
easy, or that we plan on adding pluggable schedulers. Either way,
neither of those statements is really true unless you really stretch the
definitions of "easy" and "plan".
So remove this sentence as I can't imagine it does anything other than
confuse people.
Before docker, the only default was `SIGINT` for `kill_signal`. The
docker driver however defaults to `SIGTERM`, and we should document
as such.

This changes fixes a syntax error in the autoscaling apm plugin
docs as well as updates the scaling stanza doc. The stazna wording
implied its use was only for external autoscalers, whereas it also
is used by the UI.
Before, the service definition for a Connect Native service would always
require setting the `service.task` parameter. Now, that parameter is
automatically inferred when there is only one task in the task group.
Fixes#8274
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.
The suggested plugin configuration to re-enable Docker volumes was erroneously
using the singlular `volume` instead of the correct `volumes`, making the
client fail to parse the configuration and causing it not to start.
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.
Per Slack conversation on April 30 with Schmichael and Gale. Aligning navigation verbiage with other .io sites (Community instead of Resources). Page updates remove Gitter and Mailing List links to direct users to the Forum. Also changed some header content and positioning. If this all doesn't work based on full content of page, happy to brainstorm a better approach. Thank you for reviewing!
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.
