Supergraph podTemplate

The .spec.podTemplate section of your Supergraph resource allows you to customize the underlying Pods and containers.

Properties

additionalContainers

Runs additional containers alongside the main router container. This replicates the Deployment specification for containers.

1spec:
2  podTemplate:
3    additionalContainers:
4      - name: my-container
5        image: my-image:latest

additionalInitContainers

Runs additional init containers. This replicates the Deployment specification for containers.

1spec:
2  podTemplate:
3    additionalInitContainers:
4      - name: my-container
5        image: my-image:latest

affinity

The pod’s scheduling constraints. This replicates the Deployment specification for affinity.

1spec:
2  podTemplate:
3    affinity:
4      requiredDuringSchedulingIgnoredDuringExecution:
5        nodeSelectorTerms:
6        - matchExpressions:
7          - key: topology.kubernetes.io/zone
8            operator: In
9            values:
10            - us-east-1a
11            - us-east-1b

annotations

Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata.

1spec:
2  podTemplate:
3    annotations:
4      sidecar.istio.io/inject: "false"

env

List of environment variables to set in the container. Please note that the Apollo GraphOS Operator will already inject default environment variable values, such as APOLLO_API or APOLLO_GRAPH_REF.

1spec:
2  podTemplate:
3    env:
4      - name: APOLLO_ROUTER_LOG
5        value: debug

envFrom

List of ConfigMap or Secret names whose values are to be set in the container as environment variables.

1spec:
2  podTemplate:
3    envFrom:
4      - configMapRef:
5          name: my-config
6      - secretRef:
7          name: my-secret

image

Custom Apollo Router image. Please note that you cannot use image and routerVersion at the same time.

1spec:
2  podTemplate:
3    image: my-image:latest

labels

Map of string keys and values that can be used to organize and categorize (scope and select) objects.

1spec:
2  podTemplate:
3    labels:
4      app: my-app
5      tier: backend

podSecurityContext

Holds pod-level security attributes and common container settings.

1spec:
2  podTemplate:
3    podSecurityContext:
4      runAsUser: 1000
5      fsGroup: 2000

priorityClassName

Indicates the pod’s priority.

1spec:
2  podTemplate:
3    priorityClassName: high-priority

resources

Resources is the total amount of CPU and Memory resources required by all containers in the pod.

1spec:
2  podTemplate:

6        memory: "128Mi"
7      limits:
8        cpu: "500m"
9        memory: "512Mi"
