Deploy Docker Image

Deploy pre-built public container images directly to the Knative runtime.

If your application is already packaged as an OCI-compliant container image and stored in a public registry (Docker Hub, GHCR, etc.), you can deploy it instantly.

Supported Image Reference Formats

  • nginx:alpine - Docker Hub tag (defaults to library/nginx)
  • docker.io/library/nginx:alpine - Fully qualified Docker Hub reference
  • ghcr.io/your-user/your-image:latest - GitHub Container Registry reference
  • gcr.io/gcp-project/image-name:tag - Google Container Registry reference

Deploying Command

Deploy custom image
kubeletto deploy my-service --image gcr.io/kubeletto-public/hello:latest --port 8080 --wait

All deployed images must be compiled for the x86-64 (amd64) architecture. Images built only for arm64 (such as Apple Silicon) will fail with an UNSUPPORTED_ARCH exit error at runtime.
