make docker-build IMG=<some-registry>/<project-name>:<tag> | Build the operator image. |
make docker-build docker-push IMG=<some-registry>/<project-name>:<tag> | Build and push the operator image for your registry. |
make install | Install the CRDs into the cluster. |
make uninstall | Uninstall the CRDs into the cluster. |
make run | Run your controller locally and outside of the cluster. Note that this will run in the foreground, so switch to a new terminal if you want to leave it running. |

operator-sdk bundle validate ./bundle —select-optional suite=operatorframework | Validate your bundle against OperatorHub.io criteria. For further information use the flag —help. |
operator-sdk olm install | To install OLM on your cluster for development purposes. |
operator-sdk olm uninstall | To uninstall OLM from your cluster. |
make bundle-build BUNDLE_IMG=<some-registry>/<project-name-bundle>:<tag> | To build your bundle operator image. |
make bundle-build bundle-push BUNDLE_IMG=<some-registry>/<project-name-bundle>:<tag> | To build and push your bundle operator image. |
operator-sdk run bundle <some-registry>/<project-name-bundle>:<tag> | To deploy your bundle operator using OLM on your cluster for development purposes. |
operator-sdk run bundle private-registry.org/bundle:v1.2.3 —service-account sa-with-secret —pull-secret-name regcred —ca-secret-name cert-sec | Configure run bundle (and run bundle-upgrade) to use an image pull secret, non-default service account configured with that secret, and custom CA certificate secret |
Updating bundle channels
The following examples let you update the bundle with data-informed. For further information also check Upgrade your Operator and see Channel Naming.
NOTE: Note that it will carry over any customizations you have made and ensure a rolling update to the next version of your Operator.
make bundle CHANNELS=fast,preview DEFAULT_CHANNEL=stable VERSION=1.0.0 IMG=<some-registry>/<project-name-bundle>:<tag>
NOTE You can use environment variables to pass the values such as export CHANNELS=fast,preview. Note that, their values will be used by make bundle command.
To test your projects
| Command | Description |
|---|---|
operator-sdk scorecard ./bundle | Run the Scorecard tests for your bundle. |
