Export validation annotations in openapi schema #897

Closed peschmae closed 5 months ago

peschmae commented 6 months ago

Describe the problem/challenge you have Currently the openapi schema generated using ytt -f schema.yaml --data-values-schema-inspect --output openapi-v3 is missing any of the #@schema/validation rules.

Describe the solution you'd like Exporting the openapi-v3 schema, should include the named rules since they all seem to be relatively easy to map to openapi-v3.

Type ytt validation openapi validation
string min_len minLength
string max_len maxLength
integer min minimum
integer max. maximum
any not_null=(nullable) nullable=true
any one_of enum

Only one_not_null seems to be a bit more complicate to map, and could be left out.

Just realized #@schema/nullable is converted to the corresponding attribute in openapi, but the not_null validation isn't.

Since the not_null validation, is documented mostly with additional lambda condition, this could also be left out.
