service,/TEST2 is 8080 HTTP service. Modify host, accessed with HTTPS protocol respectively, the result is as follows:You can see that the "Bad Gateway" error was reversed when accessing test1. Access to Test2 is normal. This may be due to the use of the backend Tomcat service for the reason of the visa book, the failure of the visit, or the Traefik itself, which is not to be delved into.Here you can modify the configuration of Traefik, add insecureskipverify = True to solve this problem.

Guide:Kubernetes a ride on the dust to open, then the enterprise should start to kubernetes migration? Under what circumstances do you really accept it? Some of the technology frontier companies first-step practice is probably the most persuasive and reference value. This article is a good reference.1Kubernetes now rage, it is part of a massive cloud-native movement. All major cloud providers use it as a solution for deploying cloud-native application

collaboration with various teams, Kubernetes now proposes Device Plugin, CPU Manager, Hugepage, Resource Claas to support a variety of hardware. Kubernetes 1.8 is the first large-scale feature release after the founding of such a group and looks forward to more progress.Let's take a look at what's published in Kubernetes 1.8.Publish a topicKubernetes through the

region can build multiple cells. All cells share the mirrored registry, mirrored build system, load balancing system and monitoring system under this region. Configure one or more network segments for the container under the same cell, dividing each segment into separate VLANs. Compute nodes under the same cell do not deploy across machine rooms. Leengine Registry: Based on a partial modification of Docker Registry 2.0, the backend supports Ceph storage for the music vision Cloud. And in the

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.

What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's
