## Harness Pipeline Structure

### Basic Pipeline YAML

```yaml
pipeline:
  name: Example Deployment Pipeline
  identifier: example_deployment
  projectIdentifier: default
  orgIdentifier: default
  tags: {}
  stages:
    - stage:
        name: Deploy to Dev
        identifier: deploy_dev
        description: Deploy to development environment
        type: Deployment
        spec:
          deploymentType: Kubernetes
          service:
            serviceRef: my_service
            serviceInputs:
              serviceDefinition:
                type: Kubernetes
                spec:
                  variables:
                    - name: image_tag
                      type: String
                      value: <+input>
          environment:
            environmentRef: dev
            deployToAll: false
            infrastructureDefinitions:
              - identifier: dev_k8s
          execution:
            steps:
              - step:
                  name: Rollout Deployment
                  identifier: rolloutDeployment
                  type: K8sRollingDeploy
                  timeout: 10m
                  spec:
                    skipDryRun: false
            rollbackSteps:
              - step:
                  name: Rollback Rollout Deployment
                  identifier: rollbackRolloutDeployment
