Running Docker on ECS Fargate with Automated Deployments, Secrets, SSL, and More

Learn how to deploy a containerized application on AWS Fargate using GitHub Actions for automated deployments. This article by Michael Salisbury provides a step-by-step guide to running Docker on ECS Fargate, including managing secrets, SSL, and more.

You Should Know:

1. Docker Commands:

Build a Docker image:
```
docker build -t your-image-name .
```
Run a Docker container:
```
docker run -d -p 80:80 your-image-name
```

Push the Docker image to a registry:

docker tag your-image-name your-registry/your-image-name
docker push your-registry/your-image-name

2. AWS CLI Commands:

Create an ECS cluster:

aws ecs create-cluster --cluster-name your-cluster-name

aws ecs register-task-definition --cli-input-json file://task-definition.json

Run a task on Fargate:

aws ecs run-task --cluster your-cluster-name --task-definition your-task-definition --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-xxxx],securityGroups=[sg-xxxx]}"

3. GitHub Actions Workflow:

Example workflow for deploying to ECS Fargate:

name: Deploy to ECS Fargate</li>
</ul>

on:
push:
branches:
- main

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

<ul>
<li>name: Configure AWS credentials
uses: aws-actions/configure-aws-credentials@v1
with:
aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
aws-region: us-east-1</p></li>
<li><p>name: Login to Docker Hub
uses: docker/login-action@v1
with:
username: ${{ secrets.DOCKER_HUB_USERNAME }}
password: ${{ secrets.DOCKER_HUB_PASSWORD }}</p></li>
<li><p>name: Build, tag, and push Docker image
run: |
docker build -t your-dockerhub-username/your-image-name .
docker tag your-dockerhub-username/your-image-name your-dockerhub-username/your-image-name:${{ github.sha }}
docker push your-dockerhub-username/your-image-name:${{ github.sha }}</p></li>
<li><p>name: Deploy to ECS
run: |
aws ecs update-service --cluster your-cluster-name --service your-service-name --force-new-deployment

4. Managing Secrets:

Use AWS Secrets Manager to store and retrieve secrets:

aws secretsmanager create-secret --name your-secret-name --secret-string '{"username":"your-username","password":"your-password"}'
aws secretsmanager get-secret-value --secret-id your-secret-name

5. SSL Configuration:

Use AWS Certificate Manager (ACM) to manage SSL certificates:

aws acm request-certificate --domain-name your-domain.com --validation-method DNS

What Undercode Say:

Deploying containerized applications on AWS Fargate using GitHub Actions streamlines the CI/CD process, ensuring efficient and secure deployments. By leveraging Docker, AWS ECS, and GitHub Actions, developers can automate deployments, manage secrets securely, and configure SSL with ease. This approach not only enhances productivity but also ensures robust and scalable application deployments in the cloud.
