Summary

Markdown supported

In her presentation at EuRuKo 2018, Joannah Nanjekye discusses the integration of containers in Ruby application deployment, emphasizing their advantages and best practices. Containers are popular not only due to trendiness but because they enhance application deployment, portability, and scaling capabilities. Joannah outlines the evolution from physical machines to virtual machines and finally to containers, highlighting the need for efficient resource utilization.

She elaborates on how containers work as storage for application processes, allowing developers to abstract applications from their operational environments. She primarily focuses on Docker, a popular container engine, while acknowledging the relevance of virtual machines for certain use cases.

Key Points Discussed: 
- **Definition of Containers**: Containers package applications separately from the operating system to enable faster and more efficient deployment. 
- **Benefits of Containers**: Containers boost reliability in deployments, increase productivity, and facilitate application scaling. 
- **Containerization Process**: Nanjekye outlines a simple three-step process to containerize a Ruby application: creating a Dockerfile, building an image, and then running a container. 
- **Selecting Base Images**: She advises the use of lightweight base images, like Ruby Alpine, to reduce container size and improve performance, further discussing how smaller images can lead to quicker boot times and fewer security vulnerabilities. 
- **Performance and Security Considerations**: Emphasizing the importance of efficient container operations, she suggests minimizing installed packages and cleaning up after installations. 
- **Testing Containers**: Joannah concludes by advocating for the importance of testing containers, parallel to code testing, to ensure their reliability within a development pipeline.

Overall, Nanjekye's presentation serves as a practical guide for Ruby developers to leverage containers effectively and to ensure that applications are scalable, secure, and efficient.
