Individual skill
k8s-kaniko-job
Sandbox build executor for Sealos deploys: build a container image from source with an in-cluster Kaniko Job and push it to GHCR, for environments without a Docker daemon (Brain managed Devbox sandboxes). Use only when a managed deploy (SEALAI_DEPLOY_MODE=managed) needs an image built from project source; local interactive deploys build with docker buildx instead (see the use-sealos skill).

# K8s Kaniko Job
Builds `linux/amd64` images inside the Kubernetes namespace when no Docker
daemon exists. One script owns the whole flow — do not hand-roll Jobs or
Secrets around it:
```bash
python3 scripts/kaniko-build.py --image ghcr.io/<owner>/<repo>:<tag> \
[--context <dir>] [--dockerfile <path-relative-to-context>] \
[--build-arg KEY=value ...]
```
Resolve `scripts/` against this skill's directory. Run the script from the
project workspace so it finds `.sealos/build-runtime.json`.
