介绍¶

Docker is an open-source engine to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, or any major infrastructure provider.

Common use cases for Docker include:

• Automating the packaging and deployment of web applications.
• Automated testing and continuous integration/deployment.
• Deploying and scaling databases and backend services in a service-oriented environment.
• Building custom PaaS environments, either from scratch or as an extension of off-the-shelf platforms like OpenShift or Cloud Foundry.
