Shutdown V1

Definitions:

• Service

Operator will send shutdown request once all containers marked with annotation are stopped.

Example:

metadata:
  annotations:
    core.shutdown.arangodb.com/app: "wait"
    core.shutdown.arangodb.com/app2: "wait"
    container.shutdown.arangodb.com/app3: port1
spec:
  containers:
    - name: app
    - name: app2
    - name: app3
      ports:
        name: port1

Pod will receive shutdown request on port port1 if containers app and app2 will be in non running state.

Extensions

DebugPackage PreShutdown Hook

The PreShutdown hook copies all non-empty files from the debug-package-mount volume when the main container exits.

How to enable:

metadata:
  labels:
    shutdown.integration.profiles.arangodb.com/debug: enabled

This creates a Pod volume named debug-package-mount, which can be mounted to any container (including InitContainers) via the volumeMounts directive.

spec:
  containers:
  - name: XXX
    volumeMounts:
    - mountPath: /debug
      name: debug-package-mount
