Kubernetes Lifecycle Hooks

Implementing Kubernetes Lifecycle Hooks in DuploCloud

A Kubernetes Lifecycle Hook triggers events to run at different stages of a Container's lifecycle. These hooks run scripts or commands before or after a specific event, such as a container being created, started, or stopped. Lifecycle hooks perform tasks like starting services, or initializing, configuring, or verifying containers.

Implementing Kubernetes Lifecycle Hooks

You can implement Kubernetes Lifecycle Hooks while Adding a DuploCloud EKS/Native Service by adding the YAML like the example below to the Other Container Config field.

#lifecycle hook sample
lifecycle:
  postStart:
    exec:
      command:
        - /bin/sh
        - '-c'
        - date > /container-started.txt
  preStop:
    exec:
      command:
        - /usr/sbin/nginx
        - '-s'
        - quit
