To put it simply, an image requires a carrier, which is a container. As mentioned in the previous article, an additional writable file layer will be started after th

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
host can be accessed across hosts. This scheme also has the problem of limitation and expansibility: for example, the address of the physical network segment should be divided into small pieces, distributed to each host, prevent the IP conflict; The subnet partition relies on the physical switch settings, and the host address space of the Docker container depends on the physical network partition.

Server virtualization refers to the operating system and hardware to add a layer, called the hypervisor layer, the next control hardware, on the host operating system, operating system OS in file form, known as virtual machine, the main problem is the hardware utilization and flexibility of the problem, the common solution for VMware Vsphere,xen,kvm,hyper-v.. Container virtualization refers to the application of packaging in the OS to run in the form

General Linux Operating System

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
shared and reused between containers;
Changes to the data volume will be effective immediately;
Updates to the data volume do not affect mirroring;
The volume will always exist until no container is used.
The use of a data volume, similar to the mount operation of a directory or file under Linux.
To mount a local directory into a container

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.
