Kubernetes Lifecycle Hooks

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 Service by adding 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
