Manifest services are the most complex way to define services, but also most flexible option.
They allow you to directly define whatever Kubernetes objects you need for your service directly. Ruckstack does not get in your way, but it also does not make things easier for you.
It’s just you and Kubernetes.
The manifest file contains standard Kubernetes definitions separated by
apiVersion: v1 kind: Service metadata: name: nginx labels: app: nginx spec: ports: - port: 80 name: web clusterIP: None selector: app: nginx --- apiVersion: apps/v1 kind: StatefulSet metadata: name: web spec: selector: matchLabels: app: nginx # has to match .spec.template.metadata.labels serviceName: "nginx" replicas: 3 # by default is 1 template: metadata: labels: app: nginx # has to match .spec.selector.matchLabels spec: terminationGracePeriodSeconds: 10 containers: - name: nginx image: k8s.gcr.io/nginx-slim:0.8 ports: - containerPort: 80 name: web volumeMounts: - name: www mountPath: /usr/share/nginx/html volumeClaimTemplates: - metadata: name: www spec: accessModes: [ "ReadWriteOnce" ] storageClassName: "my-storage-class" resources: requests: storage: 1Gi
Defining the Service
Once you have found your service, you add a new service definition to your project.
manifestServices: - id: users manifest: users.yaml
|id||Unique identifier for this service. Used as the default for filenames and internal descriptors. Must be lowercase alphanumeric (also allows “_” and “-“).|
|manifest||The path to your yaml or json object definition. Relative to your ruckstack.yaml file.|
