kedge init generates invalid kedge file

[kadel]

▶ ./kedge init -c DeploymentConfig -i tomaskral/nonroot-nginx -p 8080 --name demo
file kedge.yml created

▶ ./kedge generate -f kedge.yml
unable to perform controller operations: unable to unmarshal data: could not unmarshal into internal struct: error unmarshaling JSON: json: cannot unmarshal number into Go struct field ServiceSpecMod.portMappings of type string

I believe this is one of the side effects of using structs to create kedge file :-(

Why there are the same types defined again in init.go https://github.com/kedgeproject/kedge/blob/d6c365baeed607fb0767b4890b38fdde1304d90e/cmd/init.go#L38d/init.go#L41 ?

It should reuse types from types.go. Otherwise, what is the point of using structs?

The current approach duplication and it is error-prone. This bug is a great example of errors this can lead to.
