Fixes https://github.com/hashicorp/nomad/issues/8544
This PR fixes a bug where using `nomad job plan ...` always report no change if the submitted job contain scaling.
The issue has three contributing factors:
1. The plan endpoint doesn't populate the required scaling policy ID; unlike the job register endpoint
2. The plan endpoint suppresses errors on job insertion - the job insertion fails here, because the scaling policy is missing the required ID
3. The scheduler reports no update necessary when the relevant job isn't in store (because the insertion failed)
This PR fixes the first two factors. Changing the scheduler to be more strict might make sense, but may violate some idempotency invariant or make the scheduler more brittle.
Before, Connect Native Tasks needed one of these to work:
- To be run in host networking mode
- To have the Consul agent configured to listen to a unix socket
- To have the Consul agent configured to listen to a public interface
None of these are a great experience, though running in host networking is
still the best solution for non-Linux hosts. This PR establishes a connection
proxy between the Consul HTTP listener and a unix socket inside the alloc fs,
bypassing the network namespace for any Connect Native task. Similar to and
re-uses a bunch of code from the gRPC listener version for envoy sidecar proxies.
Proxy is established only if the alloc is configured for bridge networking and
there is at least one Connect Native task in the Task Group.
Fixes#8290
As of 0.11.3 Vault token revocation and purging was done in batches.
However the batch size was only limited by the number of *non-expired*
tokens being revoked.
Due to bugs prior to 0.11.3, *expired* tokens were not properly purged.
Long-lived clusters could have thousands to *millions* of very old
expired tokens that never got purged from the state store.
Since these expired tokens did not count against the batch limit, very
large batches could be created and overwhelm servers.
This commit ensures expired tokens count toward the batch limit with
this one line change:
```
- if len(revoking) >= toRevoke {
+ if len(revoking)+len(ttlExpired) >= toRevoke {
```
However, this code was difficult to test due to being in a periodically
executing loop. Most of the changes are to make this one line change
testable and test it.
This introduces ember-a11y-testing to acceptance tests via a helper
wrapper that allows us to globally ignore rules that we can address
separately. It also adds fixes for the aXe rules that were failing.
By default, Docker containers get /etc/resolv.conf bound into the container
with the localhost entry stripped out. In order to resolve using the host's
dnsmasq, we need to make sure the container uses the docker0 IP as its
nameserver and that dnsmasq is listening on that port and forwarding to either
the AWS VPC DNS (so that we can query private resources like EFS) or to the
Consul DNS.
