In this post, I will illustrate how to register your Docker images in a container registry and how to deploy the containers in AWS using Fargate, a serverless compute engine designed to run containerized applications. This can take a few minutes. Fargate takes this a step further by abstracting away the machine management. Why is there a voltage on my HDMI and coaxial cables? We covered the basics of building a Fastify Docker container using TypeScript, AWS ECS Fargate and then deploying using CDK. The built-in local volume driver or a third-party volume driver can be used.

With Fargate, you dont have to provision compute for your Docker Containers, AWS manages the compute for you. Customers running Jenkins on EKS or ECS can use Fargate to run a Jenkins cluster and Jenkins agents without managing servers. If you need DinD, you need EC2 hosts for the DinD task, the rest can probably be fargate as long as they dont need access to docker.sock or host files, Use AWSVPC for the EC2 tasks, that way it can easily talk to the fargate tasks which use that networking method, You might be interested in this https://aws.amazon.com/blogs/containers/deploy-applications-on-amazon-ecs-using-docker-compose/, I think I have already been at your shoes. Through customer feedback, we have learned that many DevOps teams that manage their CD pipelines choose to run it on Amazon Elastic Container Service (Amazon ECS) or Amazon Elastic Kubernetes Service (Amazon EKS). In this blog post, we have shown how modern container image builders, such as kaniko, can run without additional Linux privileges in an Amazon ECS task running on AWS Fargate. Create a ECS Task Definition that describes your container specification, including what the URI for the image is: AWS ECR, Docker Hub, Quay.io, etc. More importantly, well take a look at the necessary IAM user and IAM role permissions, how to set them up, and what to request from your cyber security team if you need to do this at work.

These replace Docker Engine's in-process logging drivers, which Fargate uses prior to platform version 1.4 and provide the same set of features. I would not install docker or related tools and manage the containers myself because that defeats half the point of ECS. You can further reduce your Fargate costs by getting a Compute Savings Plan. With Fargate, your Kubernetes data plane scales automatically as pods are created and terminated. Finally, we configure a health check for the AWS Application Load Balancer, so that it knows the service is healthy and ready to receive traffic. The second is arguably unnecessary, but it will save everyone the time and pain of many back and forth emails as they try to work out exactly which permissions you need. After reading the comments, here is my answer Technically it is possible to have multiple containers running in a task; multiple tasks running in a service; and multiple services running in a cluster. cd fastify .
