The document discusses Jirayut Nimsaeng's presentation on using Docker for continuous delivery of Joomla projects. Some key points: - Jirayut is interested in cloud, open source, and has worked with Docker since version 0.6 - Docker allows for reliable, consistent, and efficient deployment across environments like development, testing, and production - The presentation covers using Dockerfiles to build images, Docker workflows, and examples of using Docker for development environments and continuous delivery pipelines.

Docker can
● Deploy reliably & consistently
● Everything will be exactly the same
– Distros
– Software versions
– Library dependencies
● If it works locally, it will work everywhere

Docker can
● Deploy efficiently
– Laptop can run 10-100 containers easily
– Server can run 10-1000 containers
● Containers can run at native speeds

● Dockerfile is instructions to build Docker image
– How to run commands
– Add files or directories
– Create environment variables
– What process to run when launching container
