whatever, a new container is assigned.However, Docker is built on the basis of LXC. As with any container technology, it has its own file system, storage system, processor, and memory components, as far as the program is concerned. The difference between a container and a virtual machine is that the hypervisor abstrac

SUSE Linux Enterprise-class servers. As for Docker, all containers must use the same operating system and kernel. On the other hand, if you just want to make as many server applications as possible run on as few hardware as possible, you may not be interested in running multiple operating system virtual machines. If multiple copies of the same application are exactly what you need, then you will love the container. Switch to Docker this

testing, the current code is a version that can be deployed directly (artifact). All files of this version are packaged ( tar filename.tar * ) archived and sent to the production server.The production server will package the files, unpack them into a local directory, point the symbolic Link (symlink) of the running path to the directory, and then restart the app. The deployment tools in this area are ansible
