Installing the Operator SDK CLI

The Operator SDK provides a command-line interface (CLI) tool that Operator developers can use to build, test, and deploy an Operator. You can install the Operator SDK CLI on your workstation so that you are prepared to start authoring your own Operators.

The Red Hat-supported version of the Operator SDK CLI tool, including the related scaffolding and testing tools for Operator projects, is deprecated and is planned to be removed in a future release of OKD. Red Hat will provide bug fixes and support for this feature during the current release lifecycle, but this feature will no longer receive enhancements and will be removed from future OKD releases.

The Red Hat-supported version of the Operator SDK is not recommended for creating new Operator projects. Operator authors with existing Operator projects can use the version of the Operator SDK CLI tool released with OKD 4 to maintain their projects and create Operator releases targeting newer versions of OKD.

The following related base images for Operator projects are not deprecated. The runtime functionality and configuration APIs for these base images are still supported for bug fixes and for addressing CVEs.

  • The base image for Ansible-based Operator projects

  • The base image for Helm-based Operator projects

For the most recent list of major functionality that has been deprecated or removed within OKD, refer to the Deprecated and removed features section of the OKD release notes.

For information about the unsupported, community-maintained, version of the Operator SDK, see Operator SDK (Operator Framework).

Operator authors with cluster administrator access to a Kubernetes-based cluster, such as OKD, can use the Operator SDK CLI to develop their own Operators based on Go, Ansible, Java, or Helm. Kubebuilder is embedded into the Operator SDK as the scaffolding solution for Go-based Operators, which means existing Kubebuilder projects can be used as is with the Operator SDK and continue to work. See Developing Operators for full documentation on the Operator SDK.

OKD 4 supports Operator SDK 1.36.1.
