OpenShift Enterprise and Kubernetes add the ability to orchestrate Docker-formatted containers across multi-host installations. More recently the Docker project has developed a convenient management interface for Linux containers on a host. The Linux kernel has been incorporating capabilities for container technologies for years.

Typically, each container provides a single service (often called a "micro-service"), such as a web server or a database, though containers can be used for arbitrary workloads. Many application instances can be running in containers on a single host without visibility into each others' processes, files, network, and so on. Linux container technologies are lightweight mechanisms for isolating running processes so that they are limited to interacting with only their designated resources. The basic units of OpenShift Enterprise applications are called containers. Revision History: Architecture"Ĭollapse section "5. Persistent Volume Claims"Ĭollapse section "4.10.
