Docker image, container, warehouse concept Docker mirroring Docker mirroring (image) is similar to a virtual machine image, and can be interpreted as a read-only template for the Docker engine, including a file system. For example, a mirror can fully contain the Ubuntu op

. Network namespaces Started with Linux 2.6.24 completed on Linux 2.6.29 Network-related system resources Each container has its own network device, IP address, IP routing table,/proc/net directory, port number, and so on. This also allows the same application in multiple containers on a host to be bound to port 80 on the respective container. User namespaces

Looking at the history of Docker, you'll find that Docker has been emphasizing the word "application", and Docker wants to provide containerized solutions for distributed applications.From the life cycle of the Docker application software, the development work appears to be

Preface We have mentioned earlier that if we build the Docker cluster, there will be the need for a Docker instance network connection across the host, and in order to save the IP resources of the host network, we try to use DOCKER0 own network connection, add Host network IP to the main node (container instance), This should be a more desirable business requirem

In front of our lab environment, only one Docker host container is running on this host. However, in a real environment, there will be multiple host containers that start, run, stop, and destroy related containers in these hosts, regardless of whether they are located in the same host.How can we manage such a multi-host environment efficiently?The first problem we faced was installing and configuring

Jérôme Petazzoni (Docker evangelist) Translator: Mark Shao (senior engineer, EMC China) If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per

Users can connect multiple containers to the same network. Once a container is connected to a user-defined network, the container can use another container's IP address or name to communicate wit
