A 10 minute read covering some YAML edge-cases that you should have in mind when writing complex YAML files
minus-squareEphera@lemmy.mllinkfedilinkEnglisharrow-up28·7 days agoMan, even knowing that YAML document was going to be laden with bullshit, I only spotted the unquoted version strings looking fishy. I also really dislike how often YAML is abused to take keys as list items. Something like this, for example: hosts: debian-vm: user: root database-server: user: sql “debian-vm” and “database-server” are the hostname, and as such they are values. So, this should be written as: hosts: - name: debian-vm user: root - name: database-server user: sql And I’m not just nitpicking here. If we change the example a bit: hosts: database: user: sql …then suddenly, you don’t know, if “database” is just one of many possible hosts or if all hosts always have a shared database with this technology.
