Tested with `kind` and GKE. Note: "nodes" shown in `docker buildx ls` are unrelated to Kubernetes "nodes". Probably buildx should come up with an alternative term. Usage: $ kind create cluster $ export KUBECONFIG="$(kind get kubeconfig-path --name="kind")" $ docker buildx create --driver kubernetes --driver-opt replicas=3 --use $ docker buildx build -t foo --load . `--load` loads the image into the local Docker. Driver opts: - `image=IMAGE` - Sets the container image to be used for running buildkit. - `namespace=NS` - Sets the Kubernetes namespace. Defaults to the current namespace. - `replicas=N` - Sets the number of `Pod` replicas. Defaults to 1. - `rootless=(true|false)` - Run the container as a non-root user without `securityContext.privileged`. Defaults to false. - `loadbalance=(sticky|random)` - Load-balancing strategy. If set to "sticky", the pod is chosen using the hash of the context path. Defaults to "sticky" Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>
