new driver: kubernetes by AkihiroSuda · Pull Request #167 · docker/buildx (original) (raw)

Tested with kind and GKE
TODOs:

• Fix No Auth Provider found for name "gcp" error on GKE
• Support consistent hashing
• Use watch API instead of polling (maybe follow-up PR)
• Use exec API instead of executing kubectl binary
• Support rootless
• Support specifying kubeconfig via the current docker context
• Change driver name from kube to kubernetes for docker CLI consistency

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 options

• 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. Using Ubuntu host kernel is recommended. 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"
