This is a problem with all of devops imo - everything is a magic yaml config file and they're very difficult to debug or reason about unless you _just know things_.
Because most modern development practices assume you work at a trillion dollar corporation and can subsidize very poor unscalable business practices. It's baffling, especially when modern solutions are worse at making maintainable software not better IMO.
Agree. It's unfortunate that people new to development are encouraged to embrace practices that large teams in big companies have had to adopt. It might make sense for career development, but it makes for a miserable development experience, especially for someone new to it, wanting to build something for themselves. No joy in it.
