Hi, Thanks a lot for the tutorial. But I'm bit confused at one point, can you please explain that why we need to add 'products' and 'stocks' in order to view their respective output pages at the end of both of their URL's for stock page and product page (because we haven't added anything similar to this while we were accessing the 'shopfront' page). Kindly let me know if missing anything. Would really appreciate if my query is answered.

[@Thetips4you]

It depends upon the routing or components you have defined in your webpage.

Just wondering when you first time do docker "build -t tips4you/shopfront:latest ." in which tips4you is mandatory in that command, in my opinion, you can directly give "shopfront ." as well, isn't it?

[@Thetips4you]

If you want to push the image to your dockerhub, you need to give the account name. If you just want to have local image you can just give the image name alone.
