Some of the technology frontier companies first-step practice is probably the most persuasive and reference value.

Next, delete the space that Btrfs occupies #!/bin/bashfor i in ' sudo ls/var/lib/docker/btrfs/subvolumes ' do echo "Deleting $i"

The Kubernetes network model is made up of four parts from inside to outside: The network where the pod interior container resides The network where the pod resides Network for communication between pod and service Network of communication between outside and service It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [

What is the difference between Apache's Mesos and Google's kubernetes? This article comes from a question on the StackOverflow, mainly discusses the difference between Mesos and kubernetes, I believe many of us also have the question of agreeing. Kubernetes's developer Craig answered the question, while Masi also made an overview, not necessarily for the reader's reference.

The node controller of Kubernetes will delete the pod on that node, called Pod Eviction. This feature should be reasonable, but before about 1.5, all of node's pods will be deleted when all node in the cl

Kubernetes (hereinafter referred to as "k8s") is now recognized as the most advanced container cluster management tool, after the release of the 1.0 release, the development of k8s more rapidly, and has been the full support of the container ecosystem manufacturers, including coreos, rancher, etc., Many vendors that provide public cloud services also provide container services based on k8s for two developme

perspective, in Google, developers can improve productivity and service availability by using this enhanced collaborative approach, which makes the deployment on large-scale clusters more agile.However, our technology is still in its early stages of development. At present, Kubernetes has been adopted by many well-known teams of customers and companies, including RedHat, VMware, CoreOS and Mesosphere. Thes

service designed by the CoreOS team for kubernetes, which simply means that the Docker container created by the different node hosts in the cluster has a unique virtual IP address for the complete cluster. It also creates an overlay network between these IP addresses, which, through this overlay network, passes the packets intact to the target container (Overlay).Here is a schematic diagram of its network:
