kubernetes on premise

[Data Center reconstruction] -- thinking process of on-premise and On-premise Data Center reconstruction There was no clue at the beginning when I got on or off the machine. I always think it is difficult to get down from the machine, and there is a lot of computing. Later I had a small idea and wanted to display the consumption time dynamically on the interface, so the following thought came into being. Or

root of the certificate trust chain, and each component communicates on the premise that there is a certificate (root certificate) that everyone trusts, and that the certificate that everyone uses is issued by this root certificate.#所有证书相关的东西都放在这$ mkdir -p /etc/kubernetes/ca#准备生成证书的配置文件$ cp ~/kubernetes-starter/target/ca/ca-config.json /etc/

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 [

Recently, Jerry received a prototype development task that required some functions in the ABAP on Premise system (SAP CRM on-premise) to be called. The scenario is similar to the scenario described by my previous public article Cloud for customer and the integration series tutorials.The difference is that cloud for Customer (C4C) is a cloud solution whose OData service/web Service can be consumed directly b

not related to your system into your own system, and to take a step towards the efficient, flexible and configurable direction of the system.In my responsible part, the preliminary study is to check the data, how to parse the jar package, read out the Jar package class name, property name, class name description and field name description and length and other information. But this is puzzled, and later consulted Daniel, Daniel gives the idea is to use the reflection mechanism of Java, in the ne

Unconsciously learning Java for some time, this time I feel the enrichment of learning, the joy of growth.The second stage of the learning process is mainly javaweb knowledge learning, this stage will use a lot of previous knowledge, so learning new knowledge at the same time in the review of the first stage of knowledge, in the daily high-intensity learning, learned knowledge is easy to forget, so must review. This stage of learning Html,js,css,sql language, servlet,jsp Ajax,json,xml and other

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

One.In future development, see a phenomenon: see the data error is caused by thread safety problems, followed by the synchronization measures, did not expect security problems still exist.This is a painful situation because there is no solution at this time.See the problem, think that synchronization can solve the problem, did not expect to solve. (Is it a matter of security that the correct use of synchronization can be resolved?) )How is this problem caused? Here we have to introduce the

How to get along with ourselves becomes an interesting question only when we see that our spirit is hard to control our bodies. People always expect that they can live and grow as planned, and then become as successful as they dream. After that, we started planning and began to be excited for ourselves to have such a grand plan. However, we always hit the wall on the second or third day of every grand plan. The truth of the "three days of Heat" cannot be broken, but then again, so that we wil
