Speed Simplicity $ Our uniqueness
…that can be manipulated using standard operations and run consistently on virtually any hardware platform An engine that enables any payload to be encapsulated as a lightweight, portable, self-sufficient container… What is Docker?
Build once…(finally) run anywhere – 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, packaging…anything you can script – Reduce/eliminate concerns about compatibility on different platforms, either your own or your customers. Why devs care?
Configure once…run anything – 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 Why ops cares?
What it really is, is this… It is a VM without the overhead of a VM
