It is limited to containers within a single host running the Docker engine. Bridge Networksīridge networking is the most common network type. The most common network types being: bridge, overlay, and macvlan.
DOCKER NETWORK CREATE DRIVERS
See Docker Documentation: Default Networks › Docker Network Typesĭocker comes with network drivers geared towards different use cases. Each new Docker container is automatically attached to this network, unless a custom network is specified.īesides docker0, two other networks get created automatically by Docker: host (no isolation between host and containers on this network, to the outside world they are on the same network) and none (attached containers run on container-specific network stack). When Docker is installed, a default bridge network named docker0 is created. See Docker Documentation: Network Containers › Docker Default Networking (docker0) Additionally, clients from the outside world will need to access the web application container.
Docker supports different types of networks, each fit for certain use cases.įor example, building an application which runs on a single Docker container will have a different network setup as compared to a web application with a cluster with database, application and load balancers which span multiple containers that need to communicate with each other. How Containers Communicate with the Outside Worldįor Docker containers to communicate with each other and the outside world via the host machine, there has to be a layer of networking involved.How Containers Communicate with Each Other.In this page, you’ll learn everything you need to know about Docker Networking
