Ubernetes is the King of container orchestration and scheduling, it beats the competitors Docker swarm and Apache Mesos, opens the bright future, microservices can be self-repairing, can be automatically expanded, can cross zone, Region even across cloud providers for federate.

Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network

What the user needs to do is submit the resource request to the cloud platform and then fetch and consume the storage resource without worrying about which disk of the storage server The underlying store is from. to meet the storage needs of container users in the cloud environment. Kubernetes provides the concept of persistent volumes (PERSISTENTVOLUME,PV) and persistent volume requests (PE

Kubernetes has developed a Elasticsearch add-on to enable log management of the cluster. This is a combination of Elasticsearch, FLUENTD and Kibana. Elasticsearch is a search engine that is responsible for storing logs and providing query interfaces; Fluentd is responsible for collecting logs from Kubernetes and sending Elasticsearch;kibana a Web GUI that users can browse and search for stored in Logs in th
