Setup
If you plan on following along you should have installed Docker and it should be running on your computer. Make sure you’ve created a free account on Docker and signed into it with docker login from your command line.
A quick call to docker run alpine echo 'hi there' should verify that the engine is up and running by downloading the alpine linux container and running a simple echo command.
On Windows, you will need to run Linux containers for the seminar, and this can be set by going into your docker control panel and selecting Linux images. Note that your existing images will be purged and Docker will restart.
