Readiness probe

Different to a Liveness probe, a readiness probe indicates whether the application running inside of a pod is ready to work or not.

To know if the application is READY kubernetes query the readiness probe defined by the developer to check the status of the application. This can be a HTTP endpoint, a socket or a specific command.

containers:
  - name: simple-webapp
    readinessProbe:
      httpGet:
        path: /api/ready
        port: 8080
