@Al2Klimov Isn't this the same thing as https://docs.drone.io/pipeline/kubernetes/syntax/images/ ? It we misunderstood the PR can you please explain it better?

I recommend using a conversion extension [1] for this purpose:

You can use a conversion extension to modify a .drone.yml configuration file before it is parsed and processed by the system. This can be used to automatically add steps or set configuration parameters, or it can be used to convert the configuration file from a non-yaml format to yaml.

I think a more generic conversion extension that uses open policy agent / rego to enforce defaults would be awesome. This would allow anyone to set global defaults for any field in the yaml as opposed to a small subset.
