To access an Amazon Elastic Kubernetes Service (EKS) cluster within a GitHub Actions workflow, you can use the `eksctl` CLI, which is a command-line utility for working with EKS. Here are the steps to access your EKS cluster from GitHub Actions:
1. **Configure AWS Credentials**:
Before you can interact with your EKS cluster, you need to configure AWS credentials in your GitHub Actions workflow. You can do this using GitHub Secrets. Create two secrets:
- `AWS_ACCESS_KEY_ID`: Set this secret to your AWS access key ID.
- `AWS_SECRET_ACCESS_KEY`: Set this secret to your AWS secret access key.
These secrets will allow GitHub Actions to authenticate with your AWS account.
2. **GitHub Actions Workflow File**:
Create a workflow file (e.g., `.github/workflows/deploy-to-eks.yml`) in your repository. This file defines the GitHub Actions workflow. Here's an example of a basic workflow that interacts with an EKS cluster:
```yaml
name: Deploy to EKS
on:
push:
branches:
- main
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up AWS CLI
uses: aws-actions/configure-aws-credentials@v1
with:
aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
aws-region: <your-aws-region> # Replace with your AWS region
- name: Install and configure eksctl
run: |
curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64" > eksctl
chmod +x eksctl
sudo mv eksctl /usr/local/bin
- name: Authenticate with the EKS cluster
run: |
eksctl utils write-kubeconfig --cluster=<your-eks-cluster-name> --region=<your-aws-region>
kubectl config use-context <your-eks-cluster-name>
kubectl get nodes
```
In this workflow:
- The `configure-aws-credentials` action is used to configure AWS credentials using GitHub Secrets.
- The `eksctl` CLI is installed and configured.
- The EKS cluster is authenticated using `eksctl` and `kubectl`.
- A sample `kubectl` command is run to demonstrate accessing the EKS cluster. You can replace this with your specific deployment or management tasks.
3. **Customize Workflow**:
Customize the workflow according to your deployment or management requirements. You can add additional steps to deploy your application, run tests, or perform any other tasks on your EKS cluster.
4. **Push to GitHub**:
Commit and push the workflow file to your GitHub repository.
5. **Run Workflow**:
GitHub Actions will automatically run the workflow when a push event occurs on the specified branch. You can also manually trigger the workflow from the GitHub Actions interface.
This workflow allows you to access and interact with your EKS cluster from GitHub Actions, making it a part of your continuous integration and continuous deployment (CI/CD) pipeline. Make sure to secure your AWS credentials using GitHub Secrets and follow best practices for securing and managing access to your EKS clusters.
