pipeline-actions — Agent Guide

Overview

This repo provides reusable Gitea composite actions for homelab CI/CD pipelines. Actions are consumed by other projects via the full-URL form uses: https://git.ivanch.me/ivanch/pipeline-actions/<action>@main.

Actions

build-and-push (build-and-push/action.yaml)

Logs into the container registry, sets up SSH key for docker-build.haven, creates a remote Buildx context over SSH, and builds + pushes a multi-arch Docker image.

Inputs:

• image (required) — full image ref without tag
• registry_password (required) — registry password/token (use secrets)
• ssh_key (required) — SSH private key for remote builder (use secrets)
• image_tag (default latest) — tag to apply to the built image
• registry_host (default git.ivanch.me) — container registry hostname
• registry_username (default ivanch) — registry username
• platforms (default linux/amd64,linux/arm64) — target build platforms
• build_context (default .) — Docker build context path
• build_dockerfile (default Dockerfile) — Dockerfile path relative to context
• docker_host (default docker-build.haven) — remote builder hostname
• docker_user (default root) — SSH user for remote builder

deploy-restart (deploy-restart/action.yaml)

Validates KUBE_CONFIG, installs kubectl, and performs rollout restart of a Kubernetes Deployment.

Inputs:

• kube_config (required) — full kubeconfig YAML (use secrets)
• deployment_name (required) — Deployment name to restart
• namespace (default default) — Kubernetes namespace
• kube_version (default stable) — kubectl version to download

ssh-deploy (ssh-deploy/action.yaml)

SSH into a remote host, pull the latest images with docker compose pull, and recreate containers with docker compose up -d --force-recreate. Uses native ssh/ssh-keyscan — no third-party SSH action.

Inputs:

• ssh_host (required) — remote server hostname or IP
• ssh_username (required) — SSH username
• ssh_key (required) — SSH private key (use secrets)
• remote_dir (required) — directory on the remote server containing docker-compose.yml
• ssh_port (default 22) — SSH port
• compose_files (default empty) — space-separated compose file paths (applied via -f flags)

Workflow Template for New Projects

When wiring up CI/CD for a new homelab project, create .gitea/workflows/main.yaml:

name: Build and Deploy (internal)

on:
  push:
    branches:
      - main
  workflow_dispatch: {}

env:
  IMAGE: git.ivanch.me/ivanch/<PROJECT_NAME>

jobs:
  build:
    name: Build Image
    runs-on: ubuntu-amd64
    steps:
      - uses: actions/checkout@v4
      - uses: https://git.ivanch.me/ivanch/pipeline-actions/build-and-push@main
        with:
          image: ${{ env.IMAGE }}
          registry_password: ${{ secrets.REGISTRY_PASSWORD }}
          ssh_key: ${{ secrets.SSH_KEY_DOCKERBUILD }}

  deploy:
    name: Deploy (internal)
    runs-on: ubuntu-amd64
    needs: build
    steps:
      - uses: https://git.ivanch.me/ivanch/pipeline-actions/deploy-restart@main
        with:
          kube_config: ${{ secrets.KUBE_CONFIG }}
          deployment_name: <DEPLOYMENT_NAME>
          namespace: <NAMESPACE>

Required Secrets

Consumer projects must set these secrets in Gitea repo settings (Settings → Actions → Secrets):

Secret	Purpose
REGISTRY_PASSWORD	Container registry password/token for git.ivanch.me
SSH_KEY_DOCKERBUILD	SSH private key for root@docker-build.haven
KUBE_CONFIG	Full kubeconfig YAML for k8s cluster access
DEPLOY_HOST	Remote server hostname or IP (for ssh-deploy)
DEPLOY_USERNAME	SSH username for the remote server (for ssh-deploy)
DEPLOY_KEY	SSH private key for the remote server (for ssh-deploy)
DEPLOY_DIR	Directory on the remote server with docker-compose.yml (for ssh-deploy)

Rules

• Pin composite action refs to @main until version tags are created.
• Always use the full URL https://git.ivanch.me/ivanch/pipeline-actions/<action>@main for uses: — Gitea cannot resolve the bare GitHub-style ivanch/pipeline-actions/... path.
• Always use runs-on: ubuntu-amd64 (homelab Gitea runner label).
• Always build linux/amd64,linux/arm64 — the cluster has mixed arch (iris+vega=amd64, nebula+nexus=arm64).
• Workflow files go in .gitea/workflows/main.yaml of the consuming project.
• The consuming project must have a working Dockerfile at the repo root (or pass build_dockerfile input).

Do Not

• Do not add GitHub Actions workflows — these are Gitea composite actions only.
• Do not hardcode secrets in workflow files — always use ${{ secrets.* }}.
• Do not override platforms to a single arch unless there's a specific reason.
• Do not vendor dependencies — consumers reference this repo via the full-URL uses: form.
