technical bottlenecks in server deployment to fully implement an immutable infrastructure, which makes it difficult to implement in a real-world environment. Some tools such as: Packer can alleviate the difficulty of creating virtual machine images to some extent, but you still need to face a whole set of environment construction work, which usually takes a long time to build and build, because you generally need to download a few g of files to build a separate system. Is there a way to take c

Backup, recovery, and migration of containers in Docker1. Backup containerFirst, to back up the containers in Docker, we would like to look at the list of containers we want to back up. To achieve this, we need to run the Docker PS command in the Linux machine where we run the Docker engine and have created the container
