running on a virtual machine, it is like working on a real computer. Therefore, when evaluating software in a virtual machine, the system may crash, but the only thing that crashes is the operating system on the virtual machine, not the operating system on the physical computer, in addition, the recovery function of the virtual machine can immediately restore the status of the virtual machine to the status before the software is installed. Container technology manages code and applications thro

1.12. 9. Docker is not a competitorAlthough Docker is popular, it does not lack competitors. For example, CoreOS recently released a product called Rocket, and Docker's Best Linux companion, Ubuntu, is also developing its own LXD container technology. Many of these rivals are tearing up the Docker's closed ecosystem. In the Docker world, everything revolves around Docker registry, and you can either apply the public services provided by Docker o

When developing code on GitHub, we used to fork a branch and then modify the push request to the main branch, so that multiple people could be developed,But over time, the version of the fork and the main branch are becoming more and more different; Then we need to update the code from the remote branch and update it to the local branchThe following is a simple example of how to update Etcd:git remote add upstream [email protected]:coreos/etcd.gitgit

traditional virtual machine-related advantages: Can seamlessly integrate with existing virtual machine-based technologies and platforms; It greatly improves the security of the container's existing isolation technology, especially the need to share the kernel. Do not rely on existing container technology (Docker daemon, LXC, Cgroup, Namespace), only MOUNT namespace support is required. DisadvantageThe disadvantage is also obvious: Additional resource consumption i

Linux under the multi-process management tools for development and operations are very useful, common features of the main mainstream tools are Monit, supervisor. However, it is recommended to use the lightweight gadget goreman in development. Goreman is a rewrite of the widely used foreman under Ruby, after all, Golang-based tools are much easier to use. Incidentally: Goreman's author is Mattn, a Japanese programm

these problems, we introduced a series of kubernetes such as Jenkins Pipeline, and so on to help us build our CD system. The composition of the basic components of Jenkins, Docker, KUBERNETES--CDLet's introduce the basic parts that make up the CD. We have built multiple sets of kubernetes clusters for running Jenkins, running CI slow-test, and deploying demo environments. So our foundation builds are Docker, Jenkins and Kubernetes. In addition to the Jenkins cluster using a physical machine, a

OCP is the world's first open and unified standard for the container technology community. The birth of the OCP means that the dispute between Docker and CoreOS of the standard of container has been suspended. The openness of the OCP makes the standard of the container better. The OCP enables the development of the container to be widely recognized and supported, the individual or team to extend the sharing of the container technology can be more tho

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. 3. Use of third-party SDN-based solutions, such as the use of open Vswitch–ovs or
