Github Actions Github Actions

The project setup Kubernetes EKS cluster in a private subnet using cloudformation and perform the Rolling update through CI/CD pipeline. GitHub Actions are being used for CI/CD where the image has been built and pushed to the corresponding DockerHub repo post linting.

Creating Network Stack

For creating the network, run the network.yaml template with parameters file network.json

  1. Create a network setup by running the below command.

    aws cloudformation create-stack --stack-name <stack_name> --parameters file://network.json --template-body file://network.yaml

  2. Delete the stack by running the below command.

    aws cloudformation delete-stack --stack-name <stack_name>

Creating EKS Cluster

For creating the eks cluster, run the amazon-eks.yaml template with parameters file amazon-eks.json

  1. Create a amazon-eks setup by running the below command.

    aws cloudformation create-stack --stack-name <stack_name> --parameters file://amazon-eks.json --template-body file://amazon-eks.yaml --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM

  2. Delete the stack by running the below command.

    aws cloudformation delete-stack --stack-name <stack_name>

Creating EKS Cluster Worker nodes

For creating the eks cluster worker nodes, run the amazon-eks-nodegroup.yaml template with parameters file amazon-eks-nodegroup.json

  1. Create a amazon-eks-nodegroup setup by running the below command.

    aws cloudformation create-stack --stack-name <stack_name> --parameters file://amazon-eks-nodegroup.json --template-body file://amazon-eks-nodegroup.yaml --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM

  2. Delete the stack by running the below command.

    aws cloudformation delete-stack --stack-name <stack_name>

Creating Bastion instance and CI/CD User

For creating the CI/CD user and bastion nodes, run the server.yaml template with parameters file server.json

  1. Create a server setup by running the below command.

    aws cloudformation create-stack --stack-name <stack_name> --parameters file://server.json --template-body file://server.yaml --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM

  2. Delete the stack by running the below command.

    aws cloudformation delete-stack --stack-name <stack_name>

NOTE: Rename aws-auth.example.yaml to aws-auth.yaml and set the correct AWS Account Number apply using kubectl in kube-system namespace so your worker nodes can join the cluster and CI user can also have the access to the cluster.

    cp aws-auth.example.yaml aws-auth.yaml
    sed -i 's/AWS_ACCOUNT_NO/<AWS_ACCOUNT_NO>/g' aws-auth.yaml
    kubectl apply -f aws-auth.yaml
