Objectiveto report a recent blockbuster news: the latest version of Ghostcloud Enterprise container Cloud Platform Ecos (corporate Container operation System) has perfectly supported the most mainstream scheduling engine kubernetes in the container market, and officially launched today! Built-in self-research container scheduling framework Newben and open Source engine kubernetes means that the Ecos platfor

I. Introduction:Kubernetes is an open source container management tool, based on the Go language implementation, lightweight and portable applications, you can put kubernetes cluster on the Linux host deployment, management and expansion of the Docker container application on multiple hosts.Two. Architecture: 1. The kubernetes consists of the following components:

The Cluster Lifecycle layer adds self-hosted functionality to Kubeadm, which means that Kubernetes can be run on Kubernetes, which is bootstrap. Bootstrap is considered to be a system of "elegance" of a embodiment, in fact, Kubernetes in the early attempt to bootstrap, now Kubeadm directly add this feature, is undoubtedly a step closer. In addition, the KUBEADM c

From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed. Scheduling speed encountered bottlenecks, affecting the deployment of large business speed. There is no good support for stateful services. There are two solutions to this problem, one for improved refactoring of ex

After postgres8.3, the default transitions between field data are canceled. If a data transformation is required, in the Postgres database, we can use "::" To convert the field data into a type. The actual "::" is called by the cast function. exactly what fields can be converted between data? This problem can be answered only by studying the cast function. The information of the cast function is managed in the System Pg_cast table. through the query

Use Kubernetes step by stepWhy Docker and Kubernetes? Containers allow us to build, publish, and run distributed applications. They free applications from machine restrictions and allow us to create a complex application in a certain way. Writing applications using containers can bring development and QA closer to the production environment (if you try to do so ). By doing so, you can publish changes faster
