docker/cli
This repository is the home of the cli used in the Docker CE and Docker EE products.
Development
docker/cli is developed using Docker.
Build CLI from source:
$ docker buildx bake
Build binaries for all supported platforms:
$ docker buildx bake cross
Build for a specific platform:
$ docker buildx bake --set binary.platform=linux/arm64
Build dynamic binary for glibc or musl:
$ USE_GLIBC=1 docker buildx bake dynbinary
Run all linting:
$ make -f docker.Makefile lint
List all the available targets:
$ make help
In-container development environment
Start an interactive development environment:
$ make -f docker.Makefile shell
