with the mapping of internal IP addresses, each iptables rule on each host maps packets of a public-specific IP address to an internal service proxy.For cloud service providers that provide external load balancing devices, there is an easier way to achieve the same effect. On such suppliers (such as GCE), you can leave publicips as a substitute, and you can set the CREATEEXTERNALLOADBALANCER flag on the service. This launches a specific load balancer device for a cloud service provider (assumin

. Main concepts of Kubernetes 2.1 Pods In the Kubernetes system, the smallest granularity of scheduling is not simply a container, but a Pod. A Pod is the smallest deployment unit that can be created, destroyed, scheduled, and managed. One or more containers (Container) constitute a Pod. Generally, the containers in the Pod run the same application. Pods contain containers running on the same Minion (Host)

/ui, get the following result: Unauthorized Where is it not authorized? We looked at the flag options of KUBECTL Proxy and found one of the following suspects: --accept-hosts='^localhost$,^127\.0\.0\.1$,^\[::1\]$': Regular expression for hosts that the proxy should accept. It is clear that the default accepted form of the host address –accept-hosts our access restrictions. Re-adjust the configuration to execute again: # kubectl proxy --address='0.0.0.0' --port=30099 --accept-hosts='^*$'Starting

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

What is a container?Kubernetes is a container management platform. It is conceivable that we need containers to manage them. But what is a container? The best answers to the official Docker documentation are: A container image is a lightweight, standalone, executable package that contains everything that can be run: Code, runtime, System tools, system libraries, settings. For Linux and Windows-base

KeyStore will be set Spark.ssl.Kubernetes.ResourceStagingServer.KeyStore. In addition to the settings specified by the previously linked Security page, the resource relay server also supports the following additional configurations: Note that although you can set properties in Configmap, you still need to consider installing the appropriate key files into the container for the resource relay server. A common mechanism is to use kubernetes secrets a

Concept GroomingIn order to solve the above-mentioned problem, Kubernetes does not need to find a way, after all, is the network security level of the problem, every service will encounter problems, the industry has a mature solution to solve. Here we look at industry scenarios and related concepts.
