This is a collection of CloudFormation templates for launching containers in Fargate with a variety of different networking approaches.

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.

Launch the stack of your choice, and give it a friendly name in CloudFormation. For example "production" or "qa". You'll be using the name of this stack later for launching a service.

Fully public networking stack. All containers launched in this stack will have public IP addresses and can be directly accessible on the internet via an internet gateway, or indirectly accessible via a public facing load balancer.

Note that by default the security groups are configured so that the containers only accept traffic from the load balancer, even though they have public IP addresses. The capability for direct access is there if the security group is changed though. Networking stack with both public and private subnets. This stack offers the most flexibility, with the ability to host both public facing services, as well as private, internal services for which there is no public access.

Containers that are run in the private subnet can access the internet via NAT gateway. It launches containers that have public IP addresses in a public subnet, so they are directly accessible to the public. It also associates the containers with a public facing load balancer.

It launches containers that have no public IP address, and which are hosted in private subnet. If they need to make external requests, they can initiate outbound network traffic through a NAT gateway in the public subnets.

The only way to get network traffic to these private containers is via a public facing load balancer which is hosted in the public subnets. It launches containers that are hosted in a private subnet, and have no public IP address. The containers are behind an internal load balancer which is hosted in the private subnet, with no public IP address either.

This allows other containers in the subnet to make requests against the load balancer, but the load balancer is not accessible to the public internet.

These private services can still initiate outbound access the internet via the NAT gateway hosted in the public subnets. Each of the above CF stacks has default values prefilled for launching a simple Nginx container, but can be customized. It's important to make sure the "StackName" value is filled in with the same name that you selected for the name of your networking stack chosen in step 1.

Note The default instance type to build this AMI is an m4. You are charged for any instances created when building this AMI. A Makefile is provided to build the AMI, but it is just a small wrapper around invoking Packer directly. You can initiate the build process by running the following command in the root of this repository:.

The Makefile runs Packer with the eks-worker-al2. An instance is launched and the Packer Shell Provisioner runs the install-worker. The amazon-eks-nodegroup. Note that there is important Amazon EC2 user data in this CloudFormation template that bootstraps the worker nodes when they are launched so that they can register with your Amazon EKS cluster. Your nodes cannot register properly without this user data. For security issues or concerns, please do not open an issue or pull request on GitHub.

Amazon EKS also provisions elastic network interfaces in your VPC subnets to provide connectivity from the control plane instances to the worker nodes for example, to support kubectl execlogsand proxy data flows. Amazon EKS worker nodes run in your AWS account and connect to your cluster's control plane via the Kubernetes API server endpoint and a certificate file that is created for your cluster. Cluster creation typically takes between 10 and 15 minutes.

After you create an Amazon EKS cluster, you must configure your Kubernetes tooling to communicate with the API server and launch worker nodes into your cluster. Type : List of EncryptionConfig. Update requires : Replacement. The VPC configuration used by the cluster control plane.

You must specify at least two subnets. You can specify up to five security groups, but we recommend that you use a dedicated security group for your cluster control plane. Type : ResourcesVpcConfig. The desired Kubernetes version for your cluster.

If you don't specify a value here, the latest version available in Amazon EKS is used. Update requires : No interruption. When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the resource name.

From the Pipeline template, you notice we have three sections, ParametersResources and Outputs. Parameters enable us to use custom values to your template each time you create or update a stack. Github token name ii. Github username iii. Github repository name iv. Github source branch name. It is in 3 parts, the first one been CodePipelinethis describes the pipeline from Github and using the infrastructure CloudFormation template to setup staging and production environment, the second CodeBuildthis also describes the resources used to build the source and the last part of resources describes all the IAM policies needed.

Outputs which is not mandatory, is used to fetch values that can be reused in other templates. Build the Docker image and tag the image both as latest and with the Git commit ID. How to test this? After committing the changes as we can see :. We left of the previous part with docker images uploaded to ECR after source code was pulled from Github and built. Next step, set up an EKS infrastructure to pick the docker images, set up the infrastructure on EKS to deploy the application.

Since our source code is made up a javago and html microservices. Putting everything together we have the infrastructure CloudFormation template. Putting the infrastructure together with the pipeline we can set up a staging environment and a production environment. This article will be treated in 2 parts: a.

Set up of infrastructure for deployment 4. CloudFormation sets up EKS clusters for staging. Source code available on Github.
