Operators overview

modules/operators-overview.adoc

With Operators, you can create applications to monitor the running services in the cluster. Operators are designed specifically for your applications. Operators implement and automate the common Day 1 operations such as installation and configuration as well as Day 2 operations such as autoscaling up and down and creating backups. All these activities are in a piece of software running inside your cluster.

For developers

As a developer, you can perform the following Operator tasks:

• Install Operator SDK CLI.

• Create Go-based Operators, Ansible-based Operators, and Helm-based Operators.

• Use Operator SDK to build,test, and deploy an Operator.

• Install and subscribe an Operator to your namespace.

• Create an application from an installed Operator through the web console.

• Manage custom catalogs

• Allow non-cluster administrators to install Operators

• Install an Operator from OperatorHub

• View Operator status.
