Set Up GitHub Actions For API Build & Deploy

by ADMIN 45 views

=====================================================

Introduction

In this article, we will explore how to set up GitHub Actions for API build and deploy. GitHub Actions is a powerful tool that allows you to automate your software development workflow. With GitHub Actions, you can automate tasks such as building, testing, and deploying your API. In this article, we will focus on setting up GitHub Actions to build the API Docker image and deploy it to a DigitalOcean droplet or a Docker registry upon main push.

Prerequisites

Before we begin, make sure you have the following:

  • A GitHub repository containing your API code
  • A DigitalOcean account with a droplet set up
  • A Docker registry account (e.g. Docker Hub)
  • A GitHub Actions account
  • Basic knowledge of Docker and containerization

Step 1: Create a New GitHub Actions Workflow

To set up GitHub Actions, you need to create a new workflow file in your repository. This file will contain the instructions for GitHub Actions to follow. Create a new file in the .github/workflows directory of your repository, and name it api-build-deploy.yml.

Step 2: Define the Workflow

In the api-build-deploy.yml file, define the workflow using YAML syntax. The workflow should contain the following steps:

  • Build the API Docker image: Use the docker build command to build the API Docker image from the Dockerfile in your repository.
  • Push the image to a Docker registry: Use the docker push command to push the built image to a Docker registry (e.g. Docker Hub).
  • Deploy the image to a DigitalOcean droplet: Use the docker run command to deploy the image to a DigitalOcean droplet.

Here is an example of what the api-build-deploy.yml file might look like:

name: API Build & Deploy

on:
  push:
    branches:
      - main

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Login to Docker Hub
        uses: docker/login-action@v1
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}

      - name: Build the API Docker image
        run: |
          docker build -t my-api .

      - name: Push the image to Docker Hub
        run: |
          docker tag my-api:latest ${{ secrets.DOCKER_USERNAME }}/my-api:latest
          docker push ${{ secrets.DOCKER_USERNAME }}/my-api:latest

      - name: Deploy the image to DigitalOcean
        uses: digitalocean/action-droplet@v1
        with:
          api_token: ${{ secrets.DIGITALOCEAN_API_TOKEN }}
          droplet_name: my-droplet
          image: ${{ secrets.DOCKER_USERNAME }}/my-api:latest

Step 3: Configure the Workflow

In the api-build-deploy.yml file, you need to configure the workflow to use your specific Docker registry and DigitalOcean droplet. You can do this by setting environment variables and using secrets.

example, you can set the DOCKER_USERNAME and DOCKER_PASSWORD environment variables to your Docker registry credentials:

env:
  DOCKER_USERNAME: ${{ secrets.DOCKER_USERNAME }}
  DOCKER_PASSWORD: ${{ secrets.DOCKER_PASSWORD }}

You can also set the DIGITALOCEAN_API_TOKEN environment variable to your DigitalOcean API token:

env:
  DIGITALOCEAN_API_TOKEN: ${{ secrets.DIGITALOCEAN_API_TOKEN }}

Step 4: Store Secrets

To store your secrets, you need to create a new file in the .github/secrets directory of your repository. This file will contain the encrypted values of your secrets.

For example, you can create a new file called docker-credentials.yml with the following contents:

DOCKER_USERNAME: your-docker-username
DOCKER_PASSWORD: your-docker-password

You can also create a new file called digitalocean-api-token.yml with the following contents:

DIGITALOCEAN_API_TOKEN: your-digitalocean-api-token

Step 5: Trigger the Workflow

To trigger the workflow, you need to push changes to the main branch of your repository. Once you push the changes, GitHub Actions will automatically run the workflow and build and deploy your API.

Conclusion

In this article, we explored how to set up GitHub Actions for API build and deploy. We created a new workflow file, defined the workflow, configured the workflow, stored secrets, and triggered the workflow. With GitHub Actions, you can automate your software development workflow and ensure that your API is built and deployed correctly every time.

Troubleshooting

If you encounter any issues with your workflow, you can troubleshoot by checking the GitHub Actions logs. You can also use the github.actions API to debug your workflow.

Best Practices

Here are some best practices to keep in mind when setting up GitHub Actions:

  • Use environment variables to store sensitive information
  • Use secrets to store encrypted values
  • Use the github.actions API to debug your workflow
  • Use the docker and digitalocean actions to build and deploy your API
  • Use the ubuntu-latest runner to run your workflow on the latest version of Ubuntu
