\nArea Default bridge (docker0) User-defined bridge
\nNetwork deployment Docker creates upon installation Created by user
\nContainer deployment Default to this network Explicitly specify \u201c–net=[network-name]\u201d in
\n the \u201cdocker run\u201d command
\nContainer linking Allows you to link multiple containers Not supported
\n together and send connection information
\n from one to another by using
\n \u201c–link [container-name]:[service-name]\u201d.
\n When containers are linked, information
\n about a source container can be sent to
\n a recipient container.
\nPort mapping Supported e.g, by using \u201c-p 3307:3306\u201d Supported e.g, by using \u201c-p 3307:3306\u201d
\nName resolver Not supported (unless you link them) All containers in this network are able to
\n resolve each other\u2019s container name to IP address.
\n Version <1.10 use \/etc\/hosts, >=1.10 use embedded
\n DNS server.
\nPacket forwarding Yes, via iptables Yes, via iptables
\nExample usage for MySQL MySQL standalone MySQL replication, Galera Cluster, MySQL Cluster
\n (involving more than one MySQL container setup)<\/p>\n
