Regarding JSON vs YAML: It's not only about performance, but also about validation and security. If you, e.g. copy+move some lines from a JSON file to another location, most likely, the JSON will be corrupt and incorrect, and if not, it's very likely, the order didn't matter anywhere. That's good behaviour for anything that mainly computers operate, as such a copy+paste error easily happens while editing (or merging with git), but might not be reviewed by (many) humans, so might be undetected for a long time. In YAML, there is a good chance, randomly moving blocks around, the end result is a different, but still correct YAML. Indeed, that's such a common error, that for bigger projects you usually have to write an own linter for the yaml files checking e.g. if the keys are the expected ones. Regarding security: YAML specification is a bit bigger than XML, so it contains a lot of hard to implement and possible insecure options. That's why many first naive implementation of YAML parsers in programming languages were replaced over time by other parser only implementing a secure subset of YAML. (Or alternatively that's tackled by the custom linters you have to write anyway) There are some other subtle problems with YAML, e.g. your question of why you have to put "3.8" in quotes is because otherwise it would be detected as float und depending of whether can be represented in binary internally exactly or only close to it (indeed, 3.8f == 3.7999999523162841796875). The easiest way to enforce consistency is to demand that the version is always a string and not sometimes a string (3.8.0 == "3.8.0"), sometimes a float (3.8 == 3.7999999523162841796875) and sometimes an int (4 == 4). There are many more subtle possibilities to misinterpret the unquoted strings: Magic words like true or false are becoming booleans. A minus sign is very often interpreted as list start, several further characters like +, |, also have special meanings and so on. When in doubt, always put your strings into quotes, from a practical standpoint that the system should what we want to say in the yaml, even though readability is reduced. That's why, where high predictability is wanted, often enough different formats are used with less surprisings. E.g. HCL for Terraform, Programming languages for Pulumi, AWS CDK, ... or just toml/ini files. Anyway, the high readability, easy understanding and universal structure of YAML dominates pretty much every modern stack, so the solution to all the above problems are custom linters and performant YAML parsers (most often with an own subset or dialect). BTW, JSONs have disappointing also ambiguities that can even be exploited, e.g. the spec does not tell anything what should happen if a key is duplicated (which value to take). Different parsers handle that differently, and for the right combination, you can pass the validation done by the first parser to then inject some malicious (or just unintended, unwanted) behaviour to the second parser.

[@tajbir6969]

If you are wondering why the version number is string, it's because version can be something like 3.8.1 which is not a number.

[@PremKumar-mt7ff]

5:48 - You said, you attached the zip file. It's not here. Thanks for the tutorial though.

[@patrikwihlke4170]

14:09 I think that could be to allow subversions like 3.8.2 etc which would not translate well as numbers.

[@kg4lod]

Also, version is deprecated and ignored by docker. It's literally just a comment at this point. From Docker spec (emphasis in original): "A Compose implementation SHOULD NOT use this version to select an exact schema to validate the Compose file, but prefer the most recent schema at the time it has been designed."

[@samuinsaurralde2866]

Thanks for your excellent video!! Where I can download the files did you use in your examples?

[@kazemgolabpars139]

The reason version has to be in quotes for docker-compose is that yaml spec parses numbers such as 3.0 to 3 and it breaks versioning.

This was one hell of a great video. You have a great teaching style. You are VERY clear in your explanations. And best of all, your screen captures are MOBILE-FRIENDLY. This video was missing the 1 thing I came looking for, but I am glad I watched the whole thing. Liked. Subscribed. Will look over your courses and purchase any that are remotely relevant to my needs. ☮❤🌈 PS: What I needed was how to do a "reverse port map/access". That is, I need initiate "from contain to host", instead of the "from host to container" that is explained EVERYWHERE. I have since learned this is done via `docker run --add-host=host.docker.internal:host-gateway` or in docker-compose.yaml `extra_hosts: ["host.docker.internal:host-gateway"]` Then [for example] your container can access the CUPS printer on your host machine via port: 631 on host: host.docker.internal

Or both. As long as the video has a transcript enabled, it only takes a few seconds.
