The network

Many problems with Docker are caused by network settings, so it is necessary to introduce the network processing of Docker.

When the container is running, Docker provides the-- net parameter to specify the network of the container, which has four options:

-- net=bridge this is the default option and a separate network environment is assigned to the container

-- net=host lets the container use the network environment of the host. Note that this means abandoning the network isolation of the container. It allows the container to access the host, and is not recommended.

-- net=container:NAME_or_ID allows the container to share the network environment with another container so that the two can communicate with each other

-- net=none Docker does not manage the network of the container. Users can customize the network settings of the container. This option has the highest degree of freedom.
