Known limitations (NMC 2.3)#

  • No built-in push — Pushing images and charts into your registry is done with external tools (skopeo, crane, helm). A built-in push subcommand is planned for a future release.

  • Classic Helm repos only — Only Helm repositories that serve index.yaml are supported. OCI-based Helm registries (oci://) are not supported in this release.

  • No Helm image auto-discovery — Container images referenced inside Helm chart values are not discovered automatically. All images must be listed in the air-gap manifest.

  • No disk space pre-check — The nmc-airgap tool and helper scripts do not check free disk space before downloading. Ensure the output directory has enough space for the full bundle.
