One day inadvertently saw the ETCD GitHub documentation, there are some open source software developed according to ETCD, not only service discovery, there are two DNS services.

databases, caches and so on. With this scheme, the container can be connected horizontally and can be accessed vertically. The external connection container can be connected directly through the container IP address, or it can be accessed through load balancing. The container can also directly access virtual, physical machine resources, as well as MySQL and other component Services outside the Leengine system.

the concepts in Kubernetes node, Pod, Replication Controller, service, etc. can be considered as a "resource object", almost all resource objects can be implemented through the Kubectl tool (API call) to perform an increase, delete, change, Check the operation and save it in ETCD for persistent storage. From this point of view, Kubernetes is actually a highly automated resource control system, by tracking the ETC

Can only embrace the community, do not do all of their own things, one is limited number, the second is a good habit of reuse, since others have done these things, do not go to repetitive work.
