Our dnsmasq configuration needs host-specific data that we can't configure in
the AMI build. But configuring this in userdata leads to a race between
userdata execution, docker.service startup, and dnsmasq.service startup. So
rather than letting dnsmasq come up with incorrect configuration and then
modifying it after the fact, do the configuration in the service's prestart,
and have it kick off a Docker restart when we're done.
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
When a task is restored after a client restart, the template runner will
create a new lease for any dynamic secret (ex. Consul or PKI secrets
engines). But because this lease is being created in the prestart hook, we
don't trigger the `change_mode`.
This changeset uses the the existence of the task handle to detect a
previously running task that's been restored, so that we can trigger the
template `change_mode` if the template is changed, as it will be only with
dynamic secrets.
This removes small differences between the targets, like the statement
about what's being built.
The CGO/Windows related comments were deleted as being not relevant.
See https://github.com/hashicorp/nomad/pull/9643 for context.
Previously, if decoding the job, tasks, or vault portion of the config
failed, we would not return an error; it was silently ignored.
This also includes a little refactor to reduce some duplication.
When we iterate over the interfaces returned from CNI setup, we filter for one
with the `Sandbox` field set. Ensure that if none of the interfaces has that
field set that we still return an available interface.
Introduce a new more-block friendly syntax for specifying mounts with a new `mount` block type with the target as label:
```hcl
config {
image = "..."
mount {
type = "..."
target = "target-path"
volume_options { ... }
}
}
```
The main benefit here is that by `mount` being a block, it can nest blocks and avoids the compatibility problems noted in https://github.com/hashicorp/nomad/pull/9634/files#diff-2161d829655a3a36ba2d916023e4eec125b9bd22873493c1c2e5e3f7ba92c691R128-R155 .
The intention is for us to promote this `mount` blocks and quietly deprecate the `mounts` type, while still honoring to preserve compatibility as much as we could.
This addresses the issue in https://github.com/hashicorp/nomad/issues/9604 .
Add a build target for Apple Silicon (m1) macs.
Note that Go must have been built with c4f497da6f for
Nomad to work on darwin/arm64 (i.e. wait for go1.16).
Closes#9408
Make backward compatibility notes about Task Driver config options. Namely, call out the use of blocks with non-identifier attributes (like in docker systctl and storage_options) or nesting block syntax within an attribute assignment. Neither of these are valid HCL2. The solution is relatively simple: We can add = and quote the non-identifier attribute names.

https://github.com/hashicorp/nomad/pull/9608 introduced the use of the
built-in HTTP 429 response handler provided by go-connlimit. There is
concern though around plausible DOS attacks that need to be addressed,
so this PR reverts that functionality.
It keeps a fix in the tests around the use of an HTTPS enabled client
for when the server is listening on HTTPS. Previously, the tests would
fail deterministically with io.EOF because that's how the TLS server
terminates invalid connections.
Now, the result is much less deterministic. The state of the client
connection and the server socket depends on when the connection is
closed and how far along the handshake was.
CNI network configuration is currently only supported on Linux.
For now, add the linux build tag so that the deadcode linter does
not trip over unused CNI stuff on macOS.
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.
