| > Very few people were using Unix instead of DOS (or Mac OS or Windows or whatever) for their home PCs; it only got popular and people learned how to use it and later Linux because of its use in business I would say this part is correct. Your first statement is incorrect, as phrased, but I understand what you meant. Granted, you would have to wipe out all cloud providers using flavors of unix, most phones and macs to reduce the footprint. That being said, it's unpopular as a desktop OS. Phones and Macs hide it so well that most people are unaware of the underlying OS. My first Linux machine was on my work desk in 1998, while we were running racks of UltraSPARCs in production. I use docker extensively for local development in all my projects at home and at work. This guy is wrong about multiple things, eg "Well, if you’re expecting Docker to have a file-system easily accessible, you’re wrong" I can access my docker OS from: docker exec -it containername bash (allowing that it has bash). If the container OS has autocomplete and other GNU tools and features, you can get all the functionality. If you want to build that image or even upgrade the image you have (most containers have access to package management), you have a new image you can use the way you like...which might include running more than one service on the same container. Just like using a script on another unix machine, except without having to set up the physical networking or paying a host. It's very UNIX-y to provide single entry points to services and run them in relative isolation (changes to one container do not affect the others) by default. |
