Usage: $0 [options] [command]
Builds or pushes the built-in Spark Docker image.
Commands:
build Build image. Requires a repository address to be provided if the image will be
pushed to a different registry.
push Push a pre-built image to a registry. Requires a repository address to be provided.
Options:
-f file Dockerfile to build. By default builds the Dockerfile shipped with Spark.
-r repo Repository address.
-t tag Tag to apply to the built image, or to identify the image to be pushed.
-m Use minikube's Docker daemon.
Using minikube when building images will do so directly into minikube's Docker daemon.
There is no need to push the images into minikube in that case, they'll be automatically
available when running applications inside the minikube cluster.
Check the following documentation for more information on using the minikube Docker daemon:
https://kubernetes.io/docs/getting-started-guides/minikube/#reusing-the-docker-daemon
Examples:
- Build image in minikube with tag "testing"
$0 -m -t testing build
- Build and push image with tag "v2.3.0" to docker.io/myrepo
$0 -r docker.io/myrepo -t v2.3.0 build
$0 -r docker.io/myrepo -t v2.3.0 push
