Service

Provides a Kubernetes Service

Examples​

Create a NodePort service for a Deployment​

This example creates a NodePort service for use with a Deployment:

const appLabel = "myLabel";

provider.makeService({
  properties: () => ({
    metadata: {
      name: "myService",
      namespace: "monitoring",
    },
    spec: {
      selector: {
        app: appLabel,
      },
      type: "NodePort",
      ports: [
        {
          protocol: "TCP",
          port: 80,
          targetPort: 8080,
        },
      ],
    },
  }),
});

Create a Headless Service for a StatefulSet​

This example creates a Headless service for use with a StatefulSet:

const appLabel = "db";

const service = provider.makeService({
  name: "postgres-service",
  dependencies: { namespace },
  properties: () => ({
    metadata: {
      name: "postgres-service",
      namespace: "pg",
    },
    spec: {
      selector: {
        app: appLabel,
      },
      clusterIP: "None", // Headless service
      ports: [
        {
          protocol: "TCP",
          port: "5432",
          targetPort: "5432",
        },
      ],
    },
  }),
});
