Just curious, where are these recommended values coming from? I guess these should not be only for air-gapped environments, but for any env requiring workflow orchestration, no?
| . **Mirror container images** | ||
|
|
||
| Mirror all required {product-very-short}, SonataFlow, Knative, and orchestrator plugin images to an internal container registry. Ensure that the image versions match the Helm chart values. | ||
|
|
||
| . **Mirror Helm charts** | ||
|
|
||
| Pre-download the Helm charts for `redhat-developer-hub`, `orchestrator-infra`, and any dependent charts (for example, `bitnami` and `backstage`). Host them in an internal chart repository or file server. | ||
|
|
||
| . **CRD and operator installation** | ||
|
|
||
| Download the required CRDs and YAML manifests for SonataFlow and Knative operators and apply them manually. | ||
|
|
||
| . **Configure network policies** | ||
|
|
||
| Validate inter-pod communication and ensure internal DNS resolution to the mirrored image registry. |

Shouldn't the concrete steps/commands to do this be documented? Like, which version of the plugins, Helm chart to mirror exactly? We should also consider the following scenarios: partially disconnected vs fully disconnected environments.
