Add an Elastic Network Interface (ENI) to each Linux host, on a secondary subnet
we have provisioned in each AZ. Revise security groups as follows:
* Split out client security groups from servers so that we can't have clients
accidentally accessing serf addresses or other unexpected cross-talk.
* Add new security groups for the secondary subnet that only allows
communication within the security group so we can exercise behaviors with
multiple IPs.
This changeset doesn't include any Nomad configuration changes needed to take
advantage of the extra network interface. I'll include those with testing for
PR #16217.
While working on infrastructure for testing the UI in E2E, we needed
to upgrade the certificate provider. Performing a provider upgrade via
the TF `init -upgrade` brought in updates for the file and AWS
providers as well. These updates include deprecating the use of
`sensitive_content` fields, removing CA algorithm parameters that can
be inferred from keys, and removing the requirement to manually
specify AWS assume role parameters in the provider config if they're
available in the calling environment's AWS config file (as they are
via doormat or our E2E environment).
Use HCP Consul and HCP Vault for the Consul and Vault clusters used in E2E testing. This has the following benefits:
* Without the need to support mTLS bootstrapping for Consul and Vault, we can simplify the mTLS configuration by leaning on Terraform instead of janky bash shell scripting.
* Vault bootstrapping is no longer required, so we can eliminate even more janky shell scripting
* Our E2E exercises HCP, which is important to us as an organization
* With the reduction in configurability, we can simplify the Terraform configuration and drop the complicated `provision.sh`/`provision.ps1` scripts we were using previously. We can template Nomad configuration files and upload them with the `file` provisioner.
* Packer builds for Linux and Windows become much simpler.
tl;dr way less janky shell scripting!
This allows us to spin up e2e clusters with mTLS configured for all HashiCorp services, i.e. Nomad, Consul, and Vault. Used it for testing #11089 .
mTLS is disabled by default. I have not updated Windows provisioning scripts yet - Windows also lacks ACL support from before. I intend to follow up for them in another round.
Add a new driver capability: RemoteTasks.
When a task is run by a driver with RemoteTasks set, its TaskHandle will
be propagated to the server in its allocation's TaskState. If the task
is replaced due to a down node or draining, its TaskHandle will be
propagated to its replacement allocation.
This allows tasks to be scheduled in remote systems whose lifecycles are
disconnected from the Nomad node's lifecycle.
See https://github.com/hashicorp/nomad-driver-ecs for an example ECS
remote task driver.
* fix periodic
* update periodic to not use template
nomad job inspect no longer returns an apiliststub so the required fields to query job summary are no longer there, parse cli output instead
* rm tmp makefile entry
* fix typo
* revert makefile change
This PR enables jobs configured with a custom sidecar_task to make
use of the `service.expose` feature for creating checks on services
in the service mesh. Before we would check that sidecar_task had not
been set (indicating that something other than envoy may be in use,
which would not support envoy's expose feature). However Consul has
not added support for anything other than envoy and probably never
will, so having the restriction in place seems like an unnecessary
hindrance. If Consul ever does support something other than Envoy,
they will likely find a way to provide the expose feature anyway.
Fixes#9854
Terraform v0.14 is producing a lockfile after running `terraform init`.
The docs suggest we should include this file in the git repository:
> You should include this file in your version control repository so
> that you can discuss potential changes to your external dependencies
> via code review, just as you would discuss potential changes to your
> configuration itself.
Sounds similar to go.sum
