1 - Introduction

The operations to improve the platform resiliency can be automated with the automation framework provided by the Resiliency Operator.

Use cases

Recovery from a disaster

After a disaster occurs in one of your platform assets, the automation framework help in the recovery of the platform.

Key concepts

Tasks

A Task represents a configurable, reusable unit of work. It defines a plugin with a specific configuration to be executed later.

TaskRuns

A TaskRun represents a single execution of a Task. When a TaskRun is created, it triggers the execution of the plugin defined in the Task.

2 - Plugins

2.1 - Custom image

2.1.1 - Introduction

The custom-image plugins enables the deployment of a custom image to be executed as Task. This is extremely useful to run custom logic and software in the resiliency patterns.

The Pod is deployed in the Kubernetes namespace where the Task has been created.

2.1.2 - Configuration

2.1.3 - Samples

This is a list of samples of what can be perfomed as Task with the custom-image plugin.

Bash command

Run a bash command:

apiVersion: automation.astronetes.io/v1alpha1
kind: Task
metadata:
  name: hello-world
spec:
  plugin: custom-image
  config:
    image: busybox
    command:
      - echo
      - "hello world"

Kubectl command

Execute a kubectl command:

apiVersion: automation.astronetes.io/v1alpha1
kind: Task
metadata:
  name: kubectl
spec:
  plugin: custom-image
  config:
    image: bitnami/kubectl:1.27
    command:
      - kubectl
      - cluster-info
    clusterRole: cluster-admin

2.2 - Kubernetes object transformation

2.2.1 - Introduction

The custom-image plugins enables the deployment of a custom image to be executed as Task. This is extremely useful to run custom logic and software in the resiliency patterns.
