Multi-container Pod

• Definition: Have multi-cotainers in a pod, they share the same lifecycle, network and storage.
• pod.yaml:

    apiVersion: v1
    kind: Pod
    metadata:
      name: mywebapp
      labels:
        name: mywebapp
    spec:
      containers:
      - name: mywebapp
        image: mywebapp
        ports:
          containerPort: 8080
      - name: mylog
        image: mylog
        ports:
          containerPort: 8081
  

Pattern

• Sidecar: log -> log server
• Adapter: convert multi-format logs into a same format -> log server
• Ambassdor: outsource logic to a container to send logs to different databases (dev, staging, prod)
