In my last post, I showed you how to have persistent storage for your containers. Access Nginx by browsing to back to my Docker Bootcamp Series. For example, to restrict external access such that only source IP 8.8.8.8 can access the containers, the following rule could be added: iptables -I DOCKER -i extif -s 8.8.8.8 -j DROPThis series of tutorials deals with networking standalone containers which bind directly to the Docker. To allow only a specific IP or network to access the containers, insert a negated rule at the top of the DOCKER filter chain.All containers using this type are part of Docker’s virtual network and can communicate with one another. This is the default network type. Docker Network Type: Bridged – A container that has both a loopback interface and an ethernet interface that is connected to the docker bridge interface. To allow access to this host directory, the node-red user (default. Each configuration has different security implications.docker run - run this container, initially building locally if necessary -it - attach. Closed, Bridged, Joined, Open.
Docker Container Access External Network Series Of TutorialsUse when your container does not require network access. The most secure docker network type. 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. Docker Container Access External Network Full Access ToDocker 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. 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. 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. Containers are assigned a unique IP address at startup and lose the IP when stopped. Think of it as a mailing address. 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. Some examples of protocols include HTTP, FTP, TCP, and IP. 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).

Docker maintains its own virtual network that is attached to the host. Used to provide container isolation. 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). docker run -it –network none –name netclosed busybox /bin/sh Create, start and run an interactive container with a closed network container: – Creates a joined container Ck2 cheat engine tableNotice message “network is unreachable” ping -c 2 8.8.8.8 (Google’s public dns server) Try to ping an external network interface Notice the loopback interface exists (IP 127.0.0.1) Since bridged is the default type you can omit the network flag docker run -it –network bridge –name netbridge1 busybox /bin/sh docker run -it –network container:netjoin1 –name netjoin2 busybox /bin/sh Create, start and run an interactive container with a joined network docker run -it –network bridge –name netjoin1 busybox /bin/sh
