With the CDK, we can define and deploy infrastructure as code using familiar programming languages, making it easier to manage infrastructure at scale. We have now everything setup regarding the Docker Container. Reusable EC2 Instances Using Terraform Modules. In stage 1, we use the official Node.js 16-alpine image as our base image, set the working directory to /app, copy the package*.json files to the working directory, install dependencies using npm, copy the rest of the files to the working directory, and run the npm run build command. This guide uses AWS Fargate, which has a ~$0.004 (less than half of a US cent) cost per hour when using the 0.25 vCPU / 0.5 GB configuration. You should see the message Login Succeeded in the terminal, which means our local Docker CLI is authenticated to interact with the ECR. If you need to run multiple services together, you can combine them into the same task definition. Fargate takes this a step further by abstracting away the machine management.

Following the tutorial here, the example JSON file provided as an example looks like this: Since were deploying a Docker container, we need to specify a Docker image to pull some somewhere. Make sure you have a port mapping on the task definition. An ECS cluster needs a VPC in which your container instances will run, with at least 1 public or private subnet. Fargate is designed to give you significant control over how the networking of your containers works, and these templates show how to host public facing containers, containers which are indirectly accessible to the public via a load balancer but hosted within a private network, and private containers that can not be accessed by the public. Download the script to prepare the environment: With the load balancer and persistent storage configured, were ready to install Jenkins.
