This article describes the deployment of a PHP application system in the kubernetes environment. The front-end Web uses nginx, middleware PHP to run in fastcgi way, the background database is supported by MySQL master and slave.Calls between service components take the form of DNS resolution service names, and data and configuration files are persisted using PV and PVC (based on NFS).First, create a PHP image file via Dockerfile# cat dockerfile FROM docker.io/

in a service-oriented environment; Build your own PAAs environment by compiling from scratch or by extending your existing OpenShift or cloud foundry platform. Benefits of Docker 1. Simplified procedure:Docker allows developers to package their apps and dependencies into a portable container and publish them to any popular Linux machine for virtualization. Docker has changed the way virtualization is done, allowing developers to dir

Original translation from: Http://opensource.com/business/14/7/docker-security-selinuxThis article is based on a lecture I have had this year in Dockercon, which will discuss the security issues we hear about Docker containers today.Containers are not "inclusive"I hear also read many assumptions that Docker containers are the view of application sandbox-which means they can use Docker with root privileges on their systems to run arbitrary programs. They believe that the Docker containers will pr

What is Docker? Docker is an open-source engine that can easily create a lightweight, portable, self-contained container for any application. Developers compiling tests on notebooks can be deployed in bulk in a production environment, including VMS, bare metal, OpenStack clusters, and other basic application platforms.Docker is typically used in the following scenarios: Automated packaging and publishing of Web applications; Automated testing and continuous integration, release; Deployment a

Transfer from http://www.cnblogs.com/OpenShiFt/p/6008562.html Mdev Description Mdev is a simplified version of Udev from BusyBox, suitable for embedded applications. It has the characteristics of simple use. Its role is to automatically generate the required node files for the driver when the system boots up and hot-swappable or dynamically loads the driver . When building an embedded Linux root file system based on BusyBox, the optimal choice is to

: DevOps and cloud-based PaaS offerings, such as Heroku, Cloud Foundry, and OpenShift. DEVOPS enables customers to achieve business results in an agile, iterative, and incremental manner: applications can be delivered in a matter of days or weeks, rather than typically months or years. Finally, in order to achieve this development efficiency, PaaS technology is developing, enabling developers to assemble a large number of middleware components hosted

following updates: The new container security tool is already in place. In particular, CoreOs Clair and Docker security scanning make the image on the registered server more secure. container storage is more streamlined . 6 months ago, manually configuring Docker data volumes was the preferred scenario for creating persistent storage for containers. But now it's a different situation: Red Hat launched the Glusterfs-based "container-native" persistent storage project in June, CoreOS launched Tor

?The reason for this is that, after the first execution, after the completion of the. BASHRC, the next time it is executed, the Optind will not be re-generated because he is used as a global variable, so when Getopts is called, his index becomes chaotic. The reason why you do not encounter this problem in the script is also here, because each time the script executes, a new shell is called, so the Optind is set to 1. If you want him to take effect in. BASHRC, you must add the local optind to the
