Currently, the agent-template-adk image is hard-coded into the operator. An update of the image requires a new release of the operator.
In the future, there may be additional images.
There is no way to configure the operator yet. As there is no Helm Chart (yet) and kustomize has limited options to parameterize the deployment nicely.
Proposed solution: Inject environment variables from a config-map. Use a ConfigMap Generator in kustomize to ensure that the operator is redeployed on change. Users can patch the config-map with kustomize.
