Announcement​

This version of H2O MLOps adds optional role-based access control (RBAC). This feature relies on two RBAC configurations: one for the front end (FE) and the other for the back end (BE). When using RBAC, both configurations must be set up identically to ensure proper functionality and a seamless user experience.

The following is an illustrative configuration for both FE and BE RBAC. Note that in this example, it is assumed that "admin" is included in the user access token groups claim. However, it is important to customize this configuration based on your specific requirements at the time of deployment.

apiGateway:
  config:
    # -- Log verbosity.
    logLevel: "debug"
    authorization:
      # -- Whether authorization is enabled.
      enabled: true
      # -- JWT claim key which contains the role/group information.
      userJwtClaim: "groups"
      # -- List of role/group values that should have access to MLOps API Gateway as an array.
      allowedUserRoles: ["admin"]
waveApp:
  authorization:
    # -- Whether authorization is enabled.
    enabled: true
    # -- JWT claim key which contains the role/group information.
    userJwtClaim: "groups"
    # -- Comma separated list of role/group values that should have access to MLOps FE.
    allowedUserRoles: "admin"
    # -- Separator character for role/group values in JWT claim.
