Several people cloud container management tool Crane now open source

This is an era of container information bloat.

Docker whales have a round belly in Seattle opened a conference called DOCKERCON2016, the world's 4000 people to attend, 8 highlights left a more imagination of the container ecology.

Several people cloud has been focused on enterprise-class Mesos + container technology stack, out of the love of new container technology, we in the Community version of the tool to try sledgehammer, away from the DockerCon2016 has been 83 days, from a look at understanding, to in-depth research, then to open beta, unknowingly to the beginning of the school military training season.

Fork me on Github, Crane open source!

Last week (September 6) Several people cloud recruit Crane in Dockone and other channels invited instructors review, received a large wave of the inspection application, the first appearance of Dockone Crane Heart is disturbed, but fortunately there are so many senior instructors to the Docker to give love, instructors like to study new technology Technology to enjoy the thrill of technical updates, this is the Swarm of several people cloud research, released Crane, to help developers with a certain container development experience in the first time to experience the new features of Docker.

Review four days, received a lot of valuable feedback (feedback has been announced, please poke https://www.v2ex.com/t/304340#reply40 View information), to improve Crane very helpful, so the instructor moved a thought: open source, right, code open source, Let more instructors and comrades to participate in, several people cloud Crane This recruit can thrive all rely on you big, Crane want to become Super Star:)

Fork me on Github https://github.com/Dataman-Cloud/crane, Welcome to Star &fork, let the container management no longer reinvent the wheel!

About the kingdoms of Mesos, K8s and Swarm

Container ring for Docker there has been a variety of hot talk, but technology is technology, needless to argue, Docker technology is indeed a new technology, in which container orchestration is also widely watched, Mesos, k8s, Swarm three pillars, different.

Hidden in the Docker1.12 Swarm.

The following from several people cloud engineer notes

Small partners who focus on Docker technology should be aware that Docker 1.12 's Swarm mode is controversial: First people think that the Docker market drive Develop, contrary to the philosophy of Linux believers-a tool to do only one thing; Secondly, some people think that the function of Swarm mode than Mesos and k8s, is not suitable for production environment use, this point I think the biggest problem is not the function, stability is Swarm is not suitable for the production environment; Finally, the backward compatibility of Docker is also attracting countless Docker is still active develop. Other issues like container network standards and Runc have pushed Docker to the forefront. Of course, there is no doubt that Docker offers us more than that. --crane instructor Tao Baba

The main function of Docker Swarm is to learn from the "ancient times" of several products, absorbing the predecessors of the outstanding experience. Let me list a few cows to coax the function to everyone:

1. Built-in Raft, mother no longer have to worry about I also rely on Zookeeper, ETCD, Consul, light deployment of these things will waste me all day plus three machines.
2. Do not distinguish between the management node and the Worker node, want to let who on who on, guess is referring to people Nomad bar, the key can also run Promote, demote, too convenient.
3. Service, Stack plus DAB, used to say well, convenient.
4. Rolling Update, scale a Service, grayscale release minutes to do (although a bit of chicken), this needless to say also borrowed from k8s. --crane instructor Ming Uncle
