| 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: |
| -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 |
