$ operator-sdk scorecard <bundle_dir_or_image> [flags]
As an Operator author, you can use the scorecard tool in the Operator SDK to do the following tasks:
Validate that your Operator project is free of syntax errors and packaged correctly
Review suggestions about ways you can improve your Operator
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.
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). |
While the Operator SDK bundle validate
subcommand can validate local bundle directories and remote bundle images for content and structure, you can use the scorecard
command to run tests on your Operator based on a configuration file and test images. These tests are implemented within test images that are configured and constructed to be executed by the scorecard.
The scorecard assumes it is run with access to a configured Kubernetes cluster, such as OKD. The scorecard runs each test within a pod, from which pod logs are aggregated and test results are sent to the console. The scorecard has built-in basic and Operator Lifecycle Manager (OLM) tests and also provides a means to execute custom test definitions.
Create all resources required by any related custom resources (CRs) and the Operator
Create a proxy container in the deployment of the Operator to record calls to the API server and run tests
Examine parameters in the CRs
The scorecard tests make no assumptions as to the state of the Operator being tested. Creating Operators and CRs for an Operators are beyond the scope of the scorecard itself. Scorecard tests can, however, create whatever resources they require if the tests are designed for resource creation.
scorecard
command syntax$ operator-sdk scorecard <bundle_dir_or_image> [flags]
The scorecard requires a positional argument for either the on-disk path to your Operator bundle or the name of a bundle image.
For further information about the flags, run:
$ operator-sdk scorecard -h
The scorecard tool uses a configuration that allows you to configure internal plugins, as well as several global configuration options. Tests are driven by a configuration file named config.yaml
, which is generated by the make bundle
command, located in your bundle/
directory:
./bundle
...
└── tests
└── scorecard

The configuration file defines each test that scorecard can execute. The following fields of the scorecard configuration file define the test as follows:
Configuration field | Description |
---|---|
|
Test container image name that implements a test |
|
Command and arguments that are invoked in the test image to execute a test |
|
Scorecard-defined or custom labels that select which tests to run |
The scorecard ships with pre-defined tests that are arranged into suites: the basic test suite and the Operator Lifecycle Manager (OLM) suite.

A default set of Kustomize files are generated by the Operator SDK after running the init
command. The default bundle/tests/scorecard/config.yaml
file that is generated can be immediately used to run the scorecard tool against your Operator, or you can modify this file to your test specifications.
Operator project generated by using the Operator SDK
Generate or regenerate your bundle manifests and metadata for your Operator:
$ make bundle
This command automatically adds scorecard annotations to your bundle metadata, which is used by the scorecard
command to run tests.
Run the scorecard against the on-disk path to your Operator bundle or the name of a bundle image:
$ operator-sdk scorecard <bundle_dir_or_image>
The --output
flag for the scorecard
command specifies the scorecard results output format: either text
or json
.

Scorecard tests are selected by setting the --selector
CLI flag to a set of label strings. If a selector flag is not supplied, then all of the tests within the scorecard configuration file are run.
Tests are run serially with test results being aggregated by the scorecard and written to standard output, or stdout.
To select a single test, for example basic-check-spec-test
, specify the test by using the --selector
flag:
$ operator-sdk scorecard <bundle_dir_or_image> \
-o text \
--selector=test=basic-check-spec-test
To select a suite of tests, for example olm
, specify a label that is used by all of the OLM tests:
$ operator-sdk scorecard <bundle_dir_or_image> \
-o text \
--selector=suite=olm
To select multiple tests, specify the test names by using the selector
flag using the following syntax:
$ operator-sdk scorecard <bundle_dir_or_image> \
-o text \
--selector='test in (basic-check-spec-test,olm-bundle-validation-test)'
As an Operator author, you can define separate stages for your tests using the scorecard configuration file. Stages run sequentially in the order they are defined in the configuration file. A stage contains a list of tests and a configurable parallel
setting.
By default, or when a stage explicitly sets parallel
to false
, tests in a stage are run sequentially in the order they are defined in the configuration file. Running tests one at a time is helpful to guarantee that no two tests interact and conflict with each other.
However, if tests are designed to be fully isolated, they can be parallelized.
To run a set of isolated tests in parallel, include them in the same stage and set parallel
to true
:
apiVersion: scorecard.operatorframework.io/v1alpha3
kind: Configuration
metadata:
name: config
stages:
- parallel: true (1)
tests:
- entrypoint:
- scorecard-test
- basic-check-spec
image: quay.io/operator-framework/scorecard-test:v1.36.1
labels:
suite: basic
test: basic-check-spec-test
- entrypoint:
- scorecard-test
- olm-bundle-validation
image: quay.io/operator-framework/scorecard-test:v1.36.1
labels:
suite: olm
test: olm-bundle-validation-test
1 | Enables parallel testing |
All tests in a parallel stage are executed simultaneously, and scorecard waits for all of them to finish before proceding to the next stage. This can make your tests run much faster.
The scorecard tool can run custom tests that follow these mandated conventions:
Tests are implemented within a container image
Tests accept an entrypoint which include a command and arguments
Tests produce v1alpha3
scorecard output in JSON format with no extraneous logging in the test output
Tests can obtain the bundle contents at a shared mount point of /bundle
Tests can access the Kubernetes API using an in-cluster client connection
Writing custom tests in other programming languages is possible if the test image follows the above guidelines.
