Docker is a platform for developers and sysadmins to develop ship and run applications based on containers. Docker is open-source created in Go and originally on top of libvirt and LXC. Docker simplifies and standardizes the creation and management of containers.A clean safe hygienic and portable runtime environment for your app. No worries about missing dependencies packages and other pain points during subsequent deployments. Run each app in its own isolated container so you can run various versions of libraries and other dependencies for each app without worrying. Automate testing integration packaginganything you can script. Reduceeliminate concerns about compatibility on different platforms either your own or your customers.
Make the entire lifecycle more efficient consistent and repeatable. Increase the quality of code produced by developers.
Eliminate inconsistencies between development test production and customer environments. Support segregation of duties. Significantly improves the speed and reliability of continuous deployment and continuous integration systems. Because the containers are so lightweight address significant performance costs deployment and portability issues normally associated with VMs. Docker Image The basis of a Docker container.
