Javascript web application ? automated with Jenkins pipeline to create Docker image and push the image to AWS Elastic Container Registry (ECR) and deploy them on Elastic Container Service (ECS) Cluster.

? Technologies

The following tools were used in this project:

✅ Requirements

Before starting ? you need to have Git, Docker, Yarn and Node installed.

? Starting

If you want to start the project locally, you can use the following commands:

# Clone this project
git clone https://github.com/devenes/todo-ecr-ecs-cluster

# Access
cd todo-ecr-ecs-cluster

# Install dependencies
yarn install --production

# Run the project
# The server will initialize in the <http://localhost:3000>
npm run start

You can run Terraform commands in the project folder:

# Run the Terraform init command
terraform init

# Run the Terraform plan command
terraform plan
# After this command, you will see the changes that will be applied to the infrastructure
# You can run the apply command to apply the changes
terraform apply --auto-approve
  • if you want to manually run
aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.us-east-1.amazonaws.com
  • Then run the image
docker run --name todo -dp 80:3000 <aws_account_id>.dkr.ecr.us-east-1.amazonaws.com/devenes/to-do-app:latest
  • Delete the container

docker container stop todo
docker container rm todo
  • Createa ECS cluster with a unique name with the following command.
aws ecs create-cluster --cluster-name to-do-app
  • Register the task definition with the following command.
aws ecs register-task-definition --cli-input-json file://to-do-app.json
  • List the task definitions.
aws ecs list-task-definitions
  • Create a service with following command.

Note: securityGroups=[sg-e29b36ce] is default security group. If we don’t specify any security group, aws assign default security group to the cluster.

# change the subnets and security group and make sure that the 3000 port is open
aws ecs create-service --cluster to-do-app --service-name to-do-app-service --task-definition to-do-app --desired-count 1 --launch-type "FARGATE" --network-configuration "awsvpcConfiguration={subnets=[subnet-077c9758],securityGroups=[sg-e29b36ce],assignPublicIp=ENABLED}"

If you want to run the project in a Docker container, you can use the following command:

  • Build the Docker container image using the docker build command.
docker build -t todo-app:v1.0 .
  • Show the Docker image is created successfully.
docker image ls
  • Run todo app from the local Docker image.

docker run --name todo -d -p 80:3000 todo-app:v1.0
# The server will initialize in the <http://localhost:80>
  • List running container.

docker ps
# or
docker container ls
  • If necessary, authenticate the Docker CLI to your default ECR registry.
aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.us-east-1.amazonaws.com
  • Delete the ECR repository devenes-repo/todo-app from AWS CLI.

aws ecr delete-repository \
      --repository-name devenes/to-do-app \
      --force \
      --region us-east-1
  • Delete the service and ecs cluster.

aws ecs delete-service --cluster to-do-app --service to-do-app-service --force
aws ecs delete-cluster --cluster to-do-app
