docker api 开发的端口怎么获取？

Question

新版本的docker for Mac去除了docker-machine指令
我现在怎么获取 rest api 开发的端口呢？
比如：
curl -XGET http://localhost:2376/images/... | python -mjson.tool

可是，貌似不是上面的2376端口。
谢谢指教。

Answer 1

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

Answer 3

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.
https://docs.docker.com/engin...

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
