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

"Editor's note" The ETCD team recently released a beta version of ZETCD, a proxy tool that allows ETCD to be compatible with zookeeper protocols, allowing users to disassociate existing applications from the Zookeeper service.

Preface The previous article talked about some common cluster operations in ETCD, which mainly covered some common problems that might be encountered, after all, the God (Operational dimension) perspective always sees the problem and then recovers. For a cluster, it is common to process crashes, physical machine downtime, data migration backups, capacity reduction, and so on. The rest of the operation is nothing more than some common problem-handling

1. Single ETCD node (for test development)Before I have been developing a test that has been used for a ETCD node, then the Start command has been directly hitting a ETCD (I have added the bin directory of the ETCD installation directory to the PATH environment variable), and then the boot information shows

Recently tried a little etcd to do the registration discovery of the service "Etcd Service" Download the binary file from Etcd's official website and allocate three machines to do the cluster 10.0.1.98 etcd-001 10.0.1.205 etcd-002 10.0.1.182 etcd-003 Then start the service

Here the ETCD cluster is multiplexed with the 3 nodes that we tested, 3 node to install and start, note to modify the configuration file1, TLS certification file distribution: ETCD cluster authentication, in addition to the native, distributed to other node nodesSCP ca.pem KUBERNETES-KEY.PEM Kubernetes.pem [email protected]10.10. 90.106:/etc/kubernetes/SSLSCP ca.pem KUBERNETES-KEY.PEM Kubernetes.pem [email
