A good model for Docker Image initialization⚓︎

From what we learned: Basic guidance of docker, we learned how to use Docker compose to run containers in parallel. In that learning, we directly use swiftlang/swift:nightly-focal from the Docker repo. Here, we will learn how to create and use our own Docker Image in the Docker compose.

There are three steps:⚓︎

  1. Create a file named Dockerfile in your folder. About FROM, MAINTAINER, and RUN, learn from: What-is-dockerfile
    .dockerfile
    FROM swiftlang/swift:nightly-focal
    
    MAINTAINER simpli
    
    RUN apt-get update
    RUN apt update
    RUN apt -y install zsh
    RUN apt -y install curl
    RUN apt -y install vim
    RUN sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
    RUN apt-get -y install -y language-pack-en
    RUN zsh
    
  2. Then run docker build -t simpli_image [location of your dockerfile] to build a Docker Image.
  3. Finally, the yml below as docker-compose run --rm dev:
    .yml
    services:
      dev:
        image: simpli_image #"swiftlang/swift:nightly-focal"
        volumes:
          - your directory /swift:/code
        environment:
          - USER=your name 
    

Now you are using your own Docker Image in which zsh & oh-my-zsh have been pre-installed.
