### Enable CORS
To enable Cross-Origin Resource Sharing (CORS) in an Ingress rule add the annotation `ingress.kubernetes.io/enable-cors: "true"`. This will add a section in the server location enabling this functionality.
CORS can be controlled with the following annotations:
* `ingress.kubernetes.io/cors-allow-methods` controls which methods are accepted. This is a multi-valued field, separated by ',' and accepts only letters (upper and lower case).
Example: `ingress.kubernetes.io/cors-allow-methods: "PUT, GET, POST, OPTIONS"`
* `ingress.kubernetes.io/cors-allow-headers` controls which headers are accepted. This is a multi-valued field, separated by ',' and accepts letters, numbers, _ and -.
Example: `ingress.kubernetes.io/cors-allow-methods: "X-Forwarded-For, X-app123-XPTO"`
* `ingress.kubernetes.io/cors-allow-origin` controls what's the accepted Origin for CORS and defaults to '*'. This is a single field value, with the following format: http(s)://origin-site.com or http(s)://origin-site.com:port
Example: `ingress.kubernetes.io/cors-allow-origin: "https://origin-site.com:4443"`
* `ingress.kubernetes.io/cors-allow-credentials` controls if credentials can be passed during CORS operations.
Example: `ingress.kubernetes.io/cors-allow-credentials: "true"`
