+ Notice the split versions between client and server, which might be
+ unexpected. In more recent times the Docker CLI component (which provides the
+ `docker` command) has split out from the Moby project and is now maintained in:
+
+ * [docker/cli](https://github.com/docker/cli) - The Docker CLI source-code;
+ * [docker/docker-ce](https://github.com/docker/docker-ce) - The Docker CE
+ edition project, which assembles engine, CLI and other components.
+
+ The Moby project now defaults to a [fixed
+ version](https://github.com/docker/docker-ce/commits/v17.06.0-ce) of the
+ `docker` CLI for integration tests.
+
+ You may have noticed the following message when starting the container with the `shell` command:
+
+ ```none
+ Makefile:123: The docker client CLI has moved to github.com/docker/cli. For a dev-test cycle involving the CLI, run:
+ DOCKER_CLI_PATH=/host/path/to/cli/binary make shell
+ then change the cli and compile into a binary at the same location.
+ ```
+
+ By setting `DOCKER_CLI_PATH` you can supply a newer `docker` CLI to the
+ server development container for testing and for `integration-cli`
+ test-execution:
+
+ ```none
+ make DOCKER_CLI_PATH=/home/ubuntu/git/docker-ce/components/packaging/static/build/linux/docker/docker BIND_DIR=. shell
+ ...
+ # which docker
+ /usr/local/cli/docker
+ # docker --version
+ Docker version 17.09.0-dev, build
+ ```
+
+ This Docker CLI should be built from the [docker-ce
+ project](https://github.com/docker/docker-ce) and needs to be a Linux
+ binary.
+
Inside the container you are running a development version. This is the version
on the current branch. It reflects the value of the `VERSION` file at the
root of your `docker-fork` repository.
