Network mode

Bridge-net=bridge default network, create a docker0 bridge after Docker starts, and the default created container is also added to this bridge. The host-net=host container does not get a separate network namespace, but instead shares one with the host. This means that the container will not have its own network card information, but will use the host. Containers are isolated except for the network. None-net=none gets a separate network namespace, but does not do any network configuration for the container, which requires manual configuration. Container-net=container:Name/ID uses the same network namespace as the specified container, has the same network configuration information, and the two containers are isolated except for the network. The custom network is the same as the default bridge principle, but the custom network has internal DNS discovery and can communicate with each other through container name or hostname container
