Configuration

You need to add an ExtraConfig section to the configuration to enable the CORS middleware. At least one option should be defined.

• allow_origins list of strings (you can also use a wildcard, leaving it empty allows all origins too)
• allow_headers list of strings
• allow_methods list of strings
• expose_headers list of strings
• allow_credentials bool
• max_age duration (Ex: "12h", "5m", "3600s", ...)

Configuration Example

  "extra_config": {
    "github_com/devopsfaith/krakend-cors": {
      "allow_origins": [ "http://foobar.com" ],
      "allow_methods": [ "POST", "GET"],
      "max_age": "12h"
    }
  }

or leave the defaults (the defaults allows all origins):

"extra_config": {
  "github_com/devopsfaith/krakend-cors": {
    "allow_origins": []
  }
}
