Batch JobsJobsOne job creates one or more pods and ensures that a specified number of Pods are successfully terminated. When all pods are completed successfully, the job will track the process. When the number of successful finishes reaches the specified number, the job itself ends.Reference Documentation:https://kubernetes.io/docs/user-guide/jobs/This article is from the Linux SA John blog, so be sure to keep this source http://john88wang.blog.51cto.com/2165294/1894318Google production level Op

challenges and suggestions for migrating to k8s and cloud native.The problem problemEarlier this year, we started containerized deployment of the Sematext cloud, which seems to be very simple. What the enterprise needs to do is to package all the applications, create some kubernetes configurations for their resources (such as deployments, services, etc.), and then proceed. However, it is not that easy.The main problem is that everything that is used

has no intrusion into existing programming languages, programming frameworks, middleware, existing systems can easily be upgraded and migrated to the Kubernetes platform.Finally, Kubernetes is a complete distributed system support platform. Complete cluster management capabilities, including multi-layered security and access mechanisms, multi-tenant application support capabilities, transparent service reg

Kubernetes container cluster management system basic explanation, kubernetes Management SystemKubernetes Overview Kubernetes is open-source by GoogleContainer Cluster Management SystemIs an open-source version of Google's large-scale container management technology Brog, which includes the following features: Container-based application deployment, maintenance,

(such as KUBECTL, etc.), addons (such as dashboard, etc.) provide a security verification mechanism across all cluster.

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 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

There are no strict rules here, and kubernetes is so flexible.Client-goHere are a few ways to get information about kubernetes clusters and their resources, and you can use Dashboard, kubectl, or programmatic access to the Kubernetes API. Client-go all the most widely used libraries in the go language, as well as many other language versions (Java, Pyt

Docker enables more convenient management of single-machine container virtualization, where Docker is located between the operating system layer and the application layer; Relative traditional virtualization (Kvm,xen):Docker can be more flexible to implement some of the application layer functions, while the utilization of resources is also higher Relative application:Docker can better combine applications with more operating systems (mirroring), reducing the cost of deployment and

databases, caches and so on. With this scheme, the container can be connected horizontally and can be accessed vertically. The external connection container can be connected directly through the container IP address, or it can be accessed through load balancing. The container can also directly access virtual, physical machine resources, as well as MySQL and other component Services outside the Leengine system. We have written our own and CNICTL management
