windows docker-machine port

Question

windows如何设置 docker-machine 的port，默认是2375

这个端口，怎么改

Answer 1

There are two modification methods:

1. Specify it directly when creating

docker-machine Supports parameters. You can directly specify its port data when creating:

docker-machine create -d virtualbox \
    --engine-opt host=tcp://0.0.0.0:12345
    sandbox

It is recommended to take a look at the official website documentation: https://docs.docker.com/machine/reference/create/

There are some parameters with Chinese characteristics that should be added initially, such as --registry-mirroradding Alibaba Cloud Accelerator and the like.

1. Manually modify the created docker host

It is more complicated to modify the already established host. You need to modify the /var/lib/boot2docker/profile 文件，以及修改本机的 ~/.docker/machine/machines/xxxxx/config.json file in the virtual machine at the same time.

If the modification is incorrect, the connection will not be possible, and docker-machine upgrade 之后这些配置容易丢失。所以尽量使用之前在 create is the way to add parameters.
