resource object, to form a set of pod creation, deletion, and updating arrangements. When we use deployment, there is no need to care about how it creates and maintains Replicaset, all of which happen automatically. DockerSince k8s is based on containers, we have to mention Docker. At the beginning of the 2013, Docker turned out to be pregnant with the "container" of new ideas, Docker select containers as the core and foundation, container as the bas

DNS (domain Name System), which provides domain name resolution services, addresses difficult-to-remember IP address issues and maps corresponding IP addresses in a more human-readable and memorable way.The Cluster DNS extension is used to support discovery and invocation between services in a k8s clustered system.　　Component:?

policies are firewall rules that specify the types of data that are allowed to flow in and out. If required, kubernetes can block all traffic that is not explicitly allowed. This paper introduces the network policy of k8s and tests the network performance. Network PolicyK8s network policies are applied to pod groups identified by common tags. You can then use tags to emulate traditional segmented networks, which are often used to isolate layers

Original intentionSince the advent of kubernetes (k8s), the installation of complex, difficult to deploy has been the industry to spit groove, but also a lot of beginners to block outside the door. While there are also official standalone deployment options for getting Started: Minikube, and the kubeadm used to build the cluster, the domestic green network environment makes the official program extremely complex. So the community has also sprung up wi

Objective This article mainly discusses how to deploy drone to the k8s cluster, itself drone this container-based pipeline approach, and k8s is quite fit. The benefits are: k8s cluster daemon Drone-server and drone-agent. RPC features can be leveraged to dynamically adjust

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done throu

configuration start parameter binding address in the secure access address is 10.10.90.105:6443, Unsafe is 127.0.0.1:8080, here can be understood as a simple 6443 is a secure port, but only listen on the master's 10.10.90.105 IP, so to modify the config configuration file node in the master address is 10.10.90.90.105:6443, and if your master node is also node nodes, I tested this form, then your config file can only be accessed with 127.0.0.1:8080, using 6443 is not possible, That is, the
