Key Takeaways
- I love how he sums it all up in the very first sentence of the video, "Docker is a tool for running applications in an isolated environment".
- Awesome diagram explaining what you do with a Dockerfile and how it is the blueprint for an image.
- He uses a 3 line Dockerfile (that is a wrapper around a generic php Docker container) to get a php "Hellow World" running.
- Shows how to mount a Docker image to a local directory so the running container will update when your local files update (useful for developing on running docker container)
