• What Docker is ? According to Wikipedia, Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers
• Why should we care about docker ?
  • Reproductibility : We can use many technologies just by having they image in docker, making it easy to share and run applications consistently across different environments and machines. Containers are isolated from each other and bundle their own software, libraries, and configuration files ;
  • Local experiments : Set things for local experiments
  • Integration tests that are easy to implement with Docker (CI/CD)
  • Running pipelines in the cloud
  • Using Spark, Severless as AWS Lambda, Google functions, etc.

Setting-up Docker

On Windows, it’s recommended to use Git Bash (MinGW) or Windows Subsystem for Linux (WSL) to run Docker code. On Linux, we can use native terminal.

Install and Run docker

First of all, we need to install Docker if it was not done.

Once it’s installed, we need to see if it’s working correctly by running in the terminal docker run hello-world

This should output something like below 👇, meaning that Docker works.

Remember to add sudoif you encounter permission denied errors.

We can run another command, docker run -it ubuntu bash, where it means interactive mode. ubuntu is the container we are running, bashis the command we are running.
