# Harness EKS Deployments Skill

Deploy to AWS EKS via Harness CD with Native Helm, Kubernetes manifests, or GitOps.

## Use For
- EKS deployment pipelines, deployment strategies (Rolling/Canary/Blue-Green)
- Native Helm deployments, GitOps with ArgoCD, multi-environment promotion

## Deployment Types

### Native Helm Deployment
```yaml
service:
  name: my-service
  serviceDefinition:
    type: NativeHelm
    spec:
      manifests:
        - manifest:
            identifier: helm_chart
            type: HelmChart
            spec:
              store:
                type: HarnessCode
                spec:
                  repoName: my-app
                  branch: main
                  folderPath: charts/my-service
              chartName: my-service
              chartVersion: <+input>
              helmVersion: V3
      artifacts:
        primary:
          primaryArtifactRef: ecr_image
          sources:
            - identifier: ecr_image
              type: Ecr
              spec:
                connectorRef: aws_connector
                region: us-west-2
                imagePath: my-service
                tag: <+input>
```

### Kubernetes Manifest Deployment
```yaml
service:
  name: my-service
  serviceDefinition:
    type: Kubernetes
    spec:
      manifests:
        - manifest:
            identifier: k8s_manifests
            type: K8sManifest
            spec:
              store:
                type: HarnessCode
                spec:
                  repoName: my-app
                  branch: main
                  paths:
                    - k8s/base
                    - k8s/overlays/<+env.name>
```

## Deployment Strategies

### Rolling (Zero-Downtime Default)
```yaml
execution:
  steps:
    - step:
        type: K8sRollingDeploy
        name: Rolling Deploy
        identifier: rolling_deploy
        spec:
          skipDryRun: false
        timeout: 10m
  rollbackSteps:
    - step:
        type: K8sRollingRollback
        name: Rollback
