Docker++ Speed++ Development++ Dependency management++ Portability++ Component reuse++ Security? Friendly face! 10. So development with Docker is super easy, right? 11. To do things properly Kickstart your project's source code to get a minimal working sample Find out what dependencies you'll need + how to install them in Docker image Create Dockerfile for your application Build your application image Find out if there are suitable Docker images to use as other microservices for your app+learn how to use them/write your own Dockerfiles if not Find out how to launch and link all the containers properly Find out how to mount your code inside container Write a terribly long command every time you start coding (or use a container orchestration tool, which you need to learn to use) Write your code 12.
