Health checks​

ExtAuth mode​

Gate implements the gRPC Health Checking Protocol v1. We also include grpc_health_probe in all our docker images.

Here's an example of a Docker Compose setup:

version: "3"
services:
  gate:
    image: slashid/gate-free:latest
    ports:
      - "8080:8080"
    healthcheck:
      test: ["CMD", "/usr/local/bin/grpc_health_probe", "-addr=:8080"]
      interval: 5s
      timeout: 10s
      retries: 3

Here's an example of a Kubernetes v1.23+ setup using Kubernetes' built-in gRPC health checking capability:

apiVersion: v1
kind: Pod
metadata:
  name: gate
spec:
  containers:
    - name: gate
      image: slashid/gate-free:latest
      ports:
        - containerPort: 8080
      livenessProbe:
        grpc:
          port: 8080
        initialDelaySeconds: 5

Finally, an example of a Kubernetes setup using grpc_health_probe:

apiVersion: v1
kind: Pod
metadata:
  name: gate
spec:
  containers:
    - name: gate
      image: slashid/gate-free:latest
      ports:
        - containerPort: 8080
      readinessProbe:
        exec:
          command: ["/usr/local/bin/grpc_health_probe", "-addr=:8080"]
        initialDelaySeconds: 5
      livenessProbe:
        exec:
          command: ["/usr/local/bin/grpc_health_probe", "-addr=:8080"]
        initialDelaySeconds: 10
