OpenShift by Red Hat is a Platform as a Service (PaaS) that enables developers to build and deploy web applications. OpenShift provides a wide selection of programming languages and frameworks including Java, Ruby, and PHP. It also provides integrated developer tools to support the application life cycle, including Eclipse integration, JBoss Developer Studio, and Jenkins. OpenShift uses an open source ecosystem to provide a platform for mobile applications, database services, and more.
In Red Hat Enterprise Linux, the rhc package provides the OpenShift client tools. Enter the following command to see if it is installed:
rpm -q rhc
package rhc is not installed
26.1. OpenShift and SELinux
SELinux provides better security control over applications that use OpenShift because all processes are labeled according to the SELinux policy. Therefore, SELinux protects OpenShift from possible malicious attacks within different gears running on the same node.
