Try the yaml language server by red hat, it comes with a docker compose validator.

So this is a list:
And this is a dictionary:
And then when they can be combined into a list of dictionaries.
And then abother thing to note is that yaml wilL convert things into a string. So if you have ports
8080:80, this will be converted into a string, which is a clue that this is a string in a list, rather than a dictionary.That actually makes sense...thank you!
