Issue:

Dependency updates for PushProx

Changelog

Problem

PushProx has out of date dependencies and has migrated to github actions which has modified the way docker manifests are published slightly.

There have been no functional changes to PushProx besides dependency upgrades.

Context

Rancher pushprox is used inside of rancher-monitoring to federate access to protected metric endpoints in a safe manner, such as control plane metrics and node-exporter metrics in RKE2 / K3s.

Testing

The testing should revolve around testing rancher-monitoring in RKE2 and K3s and making sure the core metrics show up in dashboards, as well as verifying dashboards for integrations such as kube-state-metrics

Engineering Testing

Manual Testing

Tested pull-able docker images and helm template testing making sure the image tag has been properly updated

Automated Testing

PushProx CI.

QA Testing Considerations

• Verifying dashboards work in RKE2/K3s
• Verifying linux/amd64 and linux/arm64 setups for RKE2/K3s since docker manifests were modified slightly (verifying the images are pullable and run without issues on arm64 should be sufficient)

Regressions Considerations

• Grafana dashboards, containers running on linux/arm64

Backporting considerations

• dev-v2.8
• dev-v2.7

Validation steps

• Ensure all container images have repository and tag on the same level to ensure that all container images are included in rancher-images.txt which are used by airgap customers.

  Ex:-
    longhorn-controller:
      repository: rancher/hardened-sriov-cni
      tag: v2.6.3-build20230913
  

• Add a 👍 (thumbs up) reaction to this comment once done. CI won't pass without this reaction to the github-action bot's latest validation comment.
• Approve the PR to run the CI check.
