The previous article describes the use of Traefik for service publishing in Kubernetes 1.5.2 cluster environments. Traefik is deployed in Daemonset mode, and the connection Api-server is the HTTP protocol, and RBAC is not configured. This article describes the deployment of Traefik for service publishing in the K8s 1.9 release using the deployment method.Before you begin, you need to know what RBAC is. RBAC (role-based access control) using the Rbac.a

Article from: Listen to the Cloud blogAs our business continues to grow, our number of applications has exploded. With the growth of application explosion, the difficulty of management is increased. How to quickly complete the expansion while the business explosion is growing is a big challenge. The advent of Docker happened to solve our problem. With Docker, we can quickly complete the expansion and contraction, and the configuration is uniform and error-prone.In the Docker cluster management s

Kubernetes about the service exposure is mainly through the Nodeport way, through the binding minion host of a port, then the pod request forwarding and load balancing, but this way the defect is The service may have many, if each is bound to a node host port, the host needs to open the perimeter of a heap of ports to make services calls, management confusion Cannot apply firewall rules required by many companies The ideal way is thr

OverviewKubernetes is a powerful container orchestration tool that enables users to reliably deploy and run containerized applications on a scalable system. Within the container area, k8s has undoubtedly become a community standard for container orchestration and management, and even Docker has announced support for K8s. The fighting in the field of container orchestration has been turned around, and the dust settles, and k8s has been unanimously endorsed by the players including Google, Huawei,
