Download as PPTX, PDF1 like604 views
The document provides an introduction to Docker containers, specifically aimed at Oracle professionals, detailing their setup, features, and use cases in development, testing, and production environments. It covers how to build, ship, and operate Docker containers, including integration with Oracle technologies and the importance of containers in microservices and cloud-native architectures. The presentation emphasizes the benefits of Docker, such as efficient resource usage and streamlined deployment processes.
![Some Quick Conclusions
• Docker provides a great way to
• Build environments (application & platform)
(from simple, text based build files & public images)
• Share & Ship these environments
(either through build files or through ready-to-run images)
• Run environments making efficient use of physical resources
(that can be complex and have complex interdependencies)
• And Guido is a very nice guy
• And also:
• [Docker] Containers are pivotal in cloud native environments,
microservices architecture, DevOps and CD
• Any IT professional should know her or his way around containers

• In order to run on a Windows server,
we use a Linux VM
