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 4.17 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).

About custom resource status in Ansible-based Operators

Ansible-based Operators automatically update custom resource (CR) status subresources with generic information about the previous Ansible run. This includes the number of successful and failed tasks and relevant error messages as shown:

status:
  conditions:
  - ansibleResult:
      changed: 3
      completion: 2018-12-03T13:45:57.13329
      failures: 1
      ok: 6
      skipped: 0
    lastTransitionTime: 2018-12-03T13:45:57Z
    message: 'Status code was -1 and not [200]: Request failed: <urlopen error [Errno
      113] No route to host>'
    reason: Failed
    status: "True"
    type: Failure
  - lastTransitionTime: 2018-12-03T13:46:13Z
    message: Running reconciliation
    reason: Running
    status: "True"
    type: Running

Ansible-based Operators also allow Operator authors to supply custom status values with the k8s_status Ansible module, which is included in the operator_sdk.util collection. This allows the author to update the status from within Ansible with any key-value pair as desired.

By default, Ansible-based Operators always include the generic Ansible run output as shown above. If you would prefer your application did not update the status with Ansible output, you can track the status manually from your application.

Tracking custom resource status manually

You can use the operator_sdk.util collection to modify your Ansible-based Operator to track custom resource (CR) status manually from your application.

Prerequisites
  • Ansible-based Operator project created by using the Operator SDK

Procedure
  1. Update the watches.yaml file with a manageStatus field set to false:

    - version: v1
      group: api.example.com
      kind: <kind>
      role: <role>
      manageStatus: false
  2. Use the operator_sdk.util.k8s_status Ansible module to update the subresource. For example, to update with key test and value data, operator_sdk.util can be used as shown:

    - operator_sdk.util.k8s_status:
        api_version: app.example.com/v1
        kind: <kind>
        name: "{{ ansible_operator_meta.name }}"
        namespace: "{{ ansible_operator_meta.namespace }}"
        status:
          test: data
  3. You can declare collections in the meta/main.yml file for the role, which is included for scaffolded Ansible-based Operators:

    collections:
      - operator_sdk.util
  4. After declaring collections in the role meta, you can invoke the k8s_status module directly:

    k8s_status:
      ...
      status:
        key1: value1
