This video is a docker tutorial which explains the two main components of Docker - Docker Compose Dockerfile (docker compose vs dockerfile). • This video is part of a series and this series helps you to learn docker from scratch. This series is a docker tutorial for beginners. • What is a Docker File? • Docker can build images automatically by reading the instructions from a Dockerfile. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. • In the video we are showing a dockerfile example from which you can learn how to create dockerfile / how to write dockerfile. Dockerfile step by step procedure to create Docker Images from it. • Commonly Used Dockerfile Commands (Dockerfile Instructions): • 1. FROM • 2. RUN • 3. CMD • 4. ENTRYPOINT • 5. WORKDIR • 6. COPY • 7. ADD • 8. EXPOSE • 9. LABEL • 10. VOLUME • 11. USER • 12. ENV • 13. ARG • 14. ONBUILD • What is docker compose and what is docker compose used for? • Docker Compose is a tool to help define and share multi-container applications (introduction to docker compose). • It’s an important tool for any application that needs multiple microservices, as it allows each service to easily be in a separately managed container. • How to use Docker Compose? • We can use a YAML file to configure your application’s services. • The configuration for a docker compose file is done in docker-compose.yml. • You don’t need to place this at the root of your project like a Dockerfile. In fact, it can go anywhere, as it doesn’t depend on any other code. However, if you’re building the images locally, it will need to go in a project folder with the code being built. • In the video you can see how to use docker compose yml file and how to run docker compose file. • Video Chapters: • 0:00 - Dockerfile Basics • 0:57 - Dockerfile Explained • 3:33 - Dockerfile Commands • 6:08 - Dockerfile Build Container • 10:20 - Introduction to Docker Compose • 11:19 - Docker Compose UP • #CodingDroplets #Docker
