ETCD is a highly available key-value storage system that is used primarily for shared configuration and service discovery. ETCD is developed and maintained by CoreOS and is inspired by ZooKeeper and Doozer, which is written in the go language and handles log replication through the raft consistency algorithm to ensure strong consistency. Raft is a new consistency algorithm from Stanford, suitable for the log replication of distributed systems, raft to

[E liangshi Yiyou network] docker is an open-source application container engine that allows developers to package the content their applications and applications depend on into a portable container, then, you can publish the container to any popular Linux machine to achieve virtualization. Docker has completely released the power of virtualization. It makes application distribution, deployment, and management more efficient and easy, and relies on its own outstanding capabilities, docker has no

OCP will end the competition for the container industry, a disruptive industry's standard format. Editor's note: the English version of this article is from VentureBeat, which is compiled by the Tiandi Zhuhai sub-rudder. The competition for container standards never stops when Docker-headed containers are sweeping around the world and the original application development and release methods are revolutionized. The competition for standards, the war without smoke, has brought about a huge waste

Latest Kloxo host control panel installation and Chinese graphic tutorial I. preparations before Kloxo is successfully installed 1. Kloxo can be successfully installed on CentOS and Red Hat EL 5.x operating systems, but not CentOS6.x. Here, the tribe is installed in the Linode VPS. first, reinstall the system.

Here's how to create a firewall on your Linode: Check your Linode's default firewall rules by entering the following command:Sudo iptables-L Examine the output.

In addition, you can compile the source code of etcd to obtain the executable files of etcd. Copy the etcd and etcdctl executable files of etcd to the/usr/bin/directory. Etcd-v2.2.1-linux-amd64.tar can go to the Linux commune Resource Station download: ------------------------------------------ Split line ------------------------------------

, launched in the summer of 2014, based on Docker, which is designed to allow users to manage cloud container clusters through kubernetes clusters without requiring users to perform complex setup tasks. The system will automatically select the appropriate working node to perform the specific container cluster scheduling processing work. The core concept is the container Pod (container compartment).
