-# ADR 2494: Runner Image Tags
-
-**Date**: 2023-03-17
-
-**Status**: Accepted<!-- |Accepted|Rejected|Superceded|Deprecated -->
-
-## Context
-
-Following the [adoption of actions-runner-controller by GitHub](https://github.com/actions/actions-runner-controller/discussions/2072) and the introduction of the new runner scale set autoscaling mode, we needed to provide a basic runner image that could be used off the shelf without much friction.
-
-The [current runner image](https://github.com/actions/runner/pkgs/container/actions-runner) is published to GHCR. Each release of this image is tagged with the runner version and the most recent release is also tagged with `latest`.
-
-While the use of `latest` is common practice, we recommend that users pin a specific version of the runner image for a predictable runtime and improved security posture. However, we still notice that a large number of end users are relying on the `latest` tag & raising issues when they encounter problems.
-
-Add to that, the community actions-runner-controller maintainers have issued a [deprecation notice](https://github.com/actions/actions-runner-controller/issues/2056) of the `latest` tag for the existing runner images (https://github.com/orgs/actions-runner-controller/packages).
-
-## Decision
-
-Proceed with Option 2, keeping the `latest` tag and adding the `NOTES.txt` file to our helm charts with the notice.
-
-### Option 1: Remove the `latest` tag
-
-By removing the `latest` tag, we have to proceed with either of these options:
-
-1. Remove the runner image reference in the `values.yaml` provided with the `gha-runner-scale-set` helm chart and mark these fields as required so that users have to explicitly specify a runner image and a specific tag. This will obviously introduce more  friction for users who want to start using actions-runner-controller for the first time.
-
-```yaml
-  spec:
-    containers:
-    - name: runner
-      image: ""
-      tag: ""
-      command: ["/home/runner/run.sh"]
-```
-
-1. Pin a specific runner image tag in the `values.yaml` provided with the `gha-runner-scale-set` helm chart. This will reduce friction for users who want to start using actions-runner-controller for the first time but will require us to update the `values.yaml` with every new runner release.
-
-```yaml
-  spec:
-    containers:
-    - name: runner
-      image: "ghcr.io/actions/actions-runner"
-      tag: "v2.300.0"
-      command: ["/home/runner/run.sh"]
-```
-
-### Option 2: Keep the `latest` tag
-
-Keeping the `latest` tag is also a reasonable option especially if we don't expect to make any breaking changes to the runner image. We could enhance this by adding a [NOTES.txt](https://helm.sh/docs/chart_template_guide/notes_files/) to the helm chart which will be displayed to the user after a successful helm install/upgrade. This will help users understand the implications of using the `latest` tag and how to pin a specific version of the runner image.
-
-The runner image release workflow will need to be updated so that the image is pushed to GHCR and tagged only when the runner rollout has reached all scale units.
-
-## Consequences
-
-Proceeding with **option 1** means:
-
-1. We will enhance the runtime predictability and security posture of our end users
-1. We will have to update the `values.yaml` with every new runner release (that can be automated)
-1. We will introduce friction for users who want to start using actions-runner-controller for the first time
-
-Proceeding with **option 2** means:
-
-1. We will have to continue to maintain the `latest` tag
-1. We will assume that end users will be able to handle the implications of using the `latest` tag
-1. Runner image release workflow needs to be updated
