I adopt a compromise method here
Environment: MacOS
Type in the shell: vim ~/.bash_profile, type the following code at the end of the file

alias dest='rest_fun(){ curl --unix-socket /var/run/docker.sock http: | python -mjson.tool ;};rest_fun '

Save and exit, restart the shell.
Then you can use the dest command to implement some functions, such as listing images:
dest /images/json

/var/run/docker.sock is used by default for communication. You can use the -H parameter to specify the corresponding listening port.
If you are using the default socket communication mode, you can use curl’s unix-socket method for testing.

curl --unix-socket /var/run/docker.sock http:/v1.24/info

The above instructions are in

Server:
 Version:      1.12.1
 API version:  1.24

Can be executed normally

The port here depends on the port bound to your docker daemon.

If no port is specified when the daemon is running, it will be used by defaultunix:///var/run/docker.sock

By default the Docker daemon listens on unix:///var/run/docker.sock and the client must have root access to interact with the daemon. If a group named docker exists on your system, docker applies ownership of the socket to the group.

For example when running:

docker -d -H unix:///var/run/docker.sock -H 0.0.0.0:2376

It is equivalent to binding the default socket to 2376 of the local machine, which is what you saidhttp://localhost:2376

If you don’t want to change the configuration file, just use the mirror to proxy. Pay attention to mounting/var/run/docker.sock

docker run -d -ti -p 2375:2375 -v /var/run/docker.sock:/var/run/docker.sock ehazlett/docker-proxy:latest -i
