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

use Docker-enter to enter Docker containerDocker containers do not have sshd service, but also want to enter Docker how to do, we can use the nsenter into the Docker container namespace namespace to virtual login Docker container.

. 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

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

Docker provides a simple command of the Operation container. But his command of the container does not belong to the system. Because it is too simple, there must be a lot of deficiencies. For example, starting order, dependency checking, failure service recovery, and so on, all need a mature system service management software to complete. This article uses Redis

When Docker creates a container, it uses the bridge network by default, assigning its own IP and not allowing itself to be specified.In the actual deployment, we need to specify the container IP, not allow its own IP, especially when building a cluster, fixed IP is required.We can create our own bridge network: MyNet, when you create a
