## Summary - Add `containers/nettest/default.nix` using `dockerTools.buildLayeredImage` with curl, jq, dnsutils, cacert, and bash — equivalent to the existing Dockerfile - Update `container-tag-and-release` to require `--nix` or `--dockerfile` flag when both build types exist for a container - Update `container-list` to show `[dockerfile+nix]` label when both exist ## Deployment and Testing - [ ] SSH to ringtail, run `nix build -f containers/nettest/default.nix -o result` to verify the nix expression builds - [ ] Tag `nettest-nix-v1.0.0`, confirm `build-container-nix` workflow runs on `nix-container-builder` runner and pushes to registry - [ ] Smoke test on ringtail k3s: `kubectl run nettest --image=registry.ops.eblu.me/blumeops/nettest:v1.0.0 --restart=Never && kubectl logs nettest` - [ ] Verify `mise run container-list` shows `[dockerfile+nix]` for nettest - [ ] Verify `mise run container-tag-and-release nettest v1.1.0` prompts for build type Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/214

# Nix container build workflow
|
|
# Triggers on tags matching: <container>-v<version>
|
|
# Builds from containers/<container>/default.nix if it exists, skips otherwise
|
|
# Pushes to Zot registry via skopeo with -nix image tag suffix
|
|
#
|
|
# Examples:
|
|
# nettest-v1.0.0 -> builds containers/nettest/default.nix, pushes :v1.0.0-nix
|
|
# devpi-v2.1.0 -> skips (no default.nix)
