file system, and read and write, while the underlying read-only image does not change, which is "copy-on-write." So a container is actually Docker generating a read-write layer and its configuration data, plus the underlying read-only mirror composition. The container can be modified, but the image cannot be modified. This ensures that the containers generated from the same image are independent and non-in

Docker cluster network planning and VM network configuration "Summary" using either k8s (kubernetes) or Docker swarm requires a cluster of PCs or VMS, and network planning is the first step to starting a job. The goal of this article is to use VirtualBox on a stand-alone computer to create a CentOS 7 server cluster, especially the basics of network

The previous article said how to build a private warehouse, but after the warehouse was set up, it was not convenient to maintain the mirrors in the warehouse, Docker officially did not have a good command line interface to use, but provided APIs that could be used to view and remove mirrors by invoking these APIs, but these APIs are really hard to use, So I found out that there's an Open-source Python tool that can do that. installation First downloa

Objective There are two main ways to manage data in a Docker container (data volumes) and volume container (data Volume containers), below we introduce the data management in the Docker, the need to learn to learn it. Data volume A data volume is a special directory that can be used by a container, bypassing the file system and providing many useful features:

In the process of using Docker, users often need to be able to view the data generated by the application in the container, or need to back up the data in the container, or even share the data between multiple containers, which inevitably involves the data management operation of the container. There are two main ways to manage data in a container: Data Volumes, Data Volume Containers.Data VolumesA data vol
