    - name: Configure AWS credentials
      uses: aws-actions/configure-aws-credentials@v1
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

    - name: Login to Amazon ECR
      id: login-ecr
      uses: aws-actions/amazon-ecr-login@v1

    - name: deploy to cluster
      uses: kodermax/kubectl-aws-eks@main
      env:
        KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
        ECR_REGISTRY: ${{ steps.login-ecr.outputs.registry }}
        ECR_REPOSITORY: my-app
        IMAGE_TAG: ${{ github.sha }}
      with:
        args: set image deployment/$ECR_REPOSITORY $ECR_REPOSITORY=$ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG
        
    - name: verify deployment
      uses: kodermax/kubectl-aws-eks@main

      with:
        args: rollout status deployment/my-app

Secrets

KUBE_CONFIG_DATA – required: A base64-encoded kubeconfig file with credentials for Kubernetes to access the cluster. You can get it by running the following command:

Bash

cat $HOME/.kube/config | base64

PowerShell

$base64Data = [Convert]::ToBase64String([IO.File]::ReadAllBytes("$env:USERPROFILE\.kube\config"))
Write-Output $base64Data

Make sure that your $HOME/.kube/config doesn't contain a AWS_PROFILE, i.e. remove the following section if it exists before doing the base64 encoding:

env:
- name: AWS_PROFILE
    value: github-actions
