The IBM Application Gateway has a new home - docs.verify.ibm.com/gateway
The documentation on this site will no longer be maintained after v21.02, please update your bookmarks.
The yaml file provided below contains an example YAML configuration for an IBM Application Gateway (IAG) container which:
- Configures an IBM Security Verify tenant as the identity provider using OIDC;
- Defines a single Web application which will be proxied by the IAG;
- Defines an authorization policy for the Web application which will enforce second-factor (2FA) authentication.
version: "21.02" # # Configure an IAG container to proxy a single Web application, and define # an authorization policy for the Web application.

Please note that the values provided below are for illustrative # purposes only and don't reflect a real tenant.
