BuildKit CLI for kubectl: A New Way to Build Container Images
summary
A kubectl plugin uses BuildKit to build Dockerfiles inside a Kubernetes cluster, launching a builder pod that auto-detects containerd and dockerd and mounts the node runtime so built images are available immediately on the cluster without pushing to a registry. The CLI replicates the final image to other nodes (or skips replication if pushing to a registry), supports multi-arch builds today with registry pushes required, and runs on Kubernetes 1.14+; privileged builders are intended for dev use, not production.
