docker-build-push	Build Docker images and push to Docker Hub for Coolify deployment. Use when the user needs to (1) build a Docker image locally, (2) push an image to Docker Hub, (3) deploy to Coolify via Docker image, or (4) set up CI/CD for Docker-based deployments with Gitea Actions.

Docker Build and Push

Build Docker images locally and push to Docker Hub for Coolify deployment.

Prerequisites

1. Docker installed and running
2. Docker Hub account
3. Logged in to Docker Hub: docker login

Build and Push Workflow

1. Build the Image

docker build -t DOCKERHUB_USERNAME/IMAGE_NAME:latest .

Optional version tag:

docker build -t DOCKERHUB_USERNAME/IMAGE_NAME:v1.0.0 .

2. Test Locally (Optional)

docker run -p 3000:3000 DOCKERHUB_USERNAME/IMAGE_NAME:latest

3. Push to Docker Hub

docker push DOCKERHUB_USERNAME/IMAGE_NAME:latest

Coolify Deployment

In Coolify dashboard:

1. Create/edit service → Select Docker Image as source
2. Enter image: DOCKERHUB_USERNAME/IMAGE_NAME:latest
3. Configure environment variables
4. Deploy

Automated Deployment with Gitea Actions

Create .gitea/workflows/deploy.yaml:

name: Deploy to Coolify

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Trigger Coolify Deployment
        run: |
          curl -X POST "${{ secrets.COOLIFY_WEBHOOK_URL }}"

Setup:

1. Get Coolify Webhook URL: Service settings → Webhooks → Copy URL
2. Add to Gitea Secrets: Settings → Secrets → Add COOLIFY_WEBHOOK_URL

Full Workflow:

1. Build and push locally
2. Push code to Gitea (triggers workflow)
3. Gitea notifies Coolify
4. Coolify pulls latest image and redeploys
