Gitea Actions Runner Bootstrap

This module bootstraps a single organization-scoped Gitea Actions runner for trade-next on the sol cluster.

Design

• Runner scope: organization-level for trade-next
• Runtime: docker.io/gitea/act_runner:latest
• Job execution: docker:27-dind sidecar with a shared Unix socket
• Cluster access for workflows: dedicated trade-gitops-deployer service account, exported as the K3S_KUBECONFIG_B64 org secret
• Storage model: small persistent hostPath only for runner registration state, ephemeral Docker layer cache
• Runner labels: ubuntu-latest and k3s-deploy, both starting from the standard Gitea runner image so deployment jobs can install the exact kubectl version they need

Operator Flow

1. Prepare the org registration token secret in gitea-actions.
2. Apply the kustomize module on sol.
3. Create or refresh the deployer kubeconfig and sync it to the trade-next org secrets.
4. Push a workflow to trade-gitops and let the runner execute deployment jobs.

Bootstrap Commands

From the repository root:

./bootstrap/gitea-actions/scripts/bootstrap-sol.sh

Notes

• This runner is intentionally pinned to the sol node because the target cluster is currently single-node.
• The deployer binding is cluster-admin for the first bootstrap pass and should be narrowed once the GitOps surface is fully reconstructed.
• The runner exposes the labels ubuntu-latest and k3s-deploy.
