Integration

Note: this code snippet includes a starwars graphql example instance, make sure to replace with your own service.

1. Create a deployment.yaml with the following content

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: starwars
  spec:
    selector:
      matchLabels:
        app: starwars
    template:
      metadata:
        labels:
          app: starwars
      spec:
        containers:
          - name: starwars
            image: "inigohub/starwars:latest"
            imagePullPolicy: Always
            envFrom:
              - configMapRef:
                  name: starwars-configmap
          - name: sidecar
            image: "inigohub/sidecar:latest"
            imagePullPolicy: Always
            envFrom:
              - configMapRef:
                  name: starwars-sidecar-configmap
              - secretRef:
                  name: starwars-sidecar-token
  ---
  apiVersion: v1
  kind: ConfigMap
  metadata:
    name: starwars
    labels:
      app: starwars
  data:
    #LOG_TYPE: "json"
    #LOG_LEVEL: "debug"
    SERVICE_LISTEN_PORT: "8888"
  ---
  apiVersion: v1
  kind: Secret
  metadata:
    name: starwars-sidecar-token
  stringData:
    INIGO_SERVICE_TOKEN: "YOUR-INIGO-SERVICE-TOKEN"
  ---
  apiVersion: v1
  kind: ConfigMap
  metadata:
    name: starwars-sidecar
    labels:
      app: starwars
  data:
    #LOG_TYPE: "json"
    #LOG_LEVEL: "debug"
    INIGO_LISTEN_PORT: "80"
    INIGO_ENABLE: "true"
    INIGO_EGRESS_URL: http://localhost:8888/query
    INIGO_GRAPHQL_ROUTE: /query
    INIGO_GRAPHQL_PLAYGROUND_ROUTE: /playground
    INIGO_QUERYDATABATCH_MAX_TIME: 3s
    INIGO_QUERYDATABATCH_MAX_COUNT: "10"
  ---
  apiVersion: v1
  kind: Service
  metadata:
    name: starwars
    labels:
      app: starwars
  spec:
    type: NodePort
    ports:
      - port: 80
        targetPort: 80
    selector:
      app: starwars

2. Make sure to replace YOUR-INIGO-SERVICE-TOKEN with your own service token.

3. Make sure to change starwars with your own service and its configurations.

4. Make sure to correctly setup the INIGO_EGRESS_URL so that the ports are correctly configured.

5. Apply the configuration using:

     kubectl apply -f deployment.yaml
