The project supports translating ingress-nginx specific annotations.
Current supported annotations:
nginx.ingress.kubernetes.io/canary: If set to true will enable weighting backends.nginx.ingress.kubernetes.io/canary-by-header: If specified, the value of this annotation is the header name that will be added as a HTTPHeaderMatch for the routes- generated from this Ingress. If not specified, no HTTPHeaderMatch will be generated.
nginx.ingress.kubernetes.io/canary-by-header-value: If specified, the value of this annotation is the header value to perform an HeaderMatchExact match on in the generated HTTPHeaderMatch.nginx.ingress.kubernetes.io/canary-by-header-pattern: If specified, this is the pattern to match against for the HTTPHeaderMatch, which will be of type HeaderMatchRegularExpression.nginx.ingress.kubernetes.io/canary-weight: If specified and non-zero, this value will be applied as the weight of the backends for the routes generated from this Ingress resource.nginx.ingress.kubernetes.io/canary-weight-total
If you are reliant on any annotations not listed above, please open an issue. In the meantime you'll need to manually find a Gateway API equivalent.
