You can find a full list of commands and all available flags at.

create – Create a new container in a stopped state.

Docker maintains its own virtual network that is attached to the host.

Virtual Network – Separate from the host’s physical network interface.

Think of this like a letter going from one mailbox (a network interface), to the local post office (a network interface), to the regional post office (a network interface), to another regional post office (a network interface), down to the nearest local post office (a network interface), and finally being delivered to the correct mailbox (a network interface).

Routing – The path a message takes to get from one network interface to another.

Some examples of protocols include HTTP, FTP, TCP, and IP.

#DOCKER NETWORK TYPE HOW TO#

Protocol – A “language” that two parties agree upon so they can understand how to communicate.Think of it as multiple people at the same house that can send and receive mail using the same mailbox (network interface) but have their own designated slot in the mailbox (network interface). Port – Represents the sender or recipient of a message.Containers are assigned a unique IP address at startup and lose the IP when stopped. IP Address – Represents the location of a network interface on a network.Domain Name Service (DNS) – A protocol for mapping user-friendly names to IP addresses.Messages are sent out for delivery for people at other addresses. Messages are delivered for people at the address. Think of it like a house located at a street address with a mailbox. Network Interface – Represents the location and address of a network device.Think of it like a circular driveway that does not connect to the network of roads.

Loopback Interface – Used to connect one network interface back to the same internal network interface.

Think of it like a driveway that connects to the network of roads. Ethernet Interface – Used to connect one network interface to other external network interfaces.Bridge Interface – Used to connect multiple networks together so they function as a single network.This is the least secure docker network type and should be used with caution. The container can bind to protected ports on the host, but not modify the network interfaces. Docker Network Type: Open – A container that has full access to the host’s network interface bypassing the docker virtual network.Use when two containers need to communicate directly through the shared loopback interface. The containers still have their own isolated memory and file systems. Docker Network Type: Joined – Two or more containers that share the same loopback and ethernet interfaces.Use when your container does not require network access. Programs running inside the container cannot connect out. Nothing outside the container can connect in. Docker Network Type: Closed – A container that has a loopback interface but not an ethernet interface.They are not accessible from the host machine by default. All containers using this type are part of Docker’s virtual network and can communicate with one another. Docker Network Type: Bridged – A container that has both a loopback interface and an ethernet interface that is connected to the docker bridge interface.Each configuration has different security implications. Terminology Docker Network Typesĭocker provides four different network configurations. I’ve included some basic network terminology, which is not directly related to Docker, for some extra background. In my last post, I showed you how to have persistent storage for your containers.
