Session Persistence

Last updated: 2023-12-26 10:46:12


    The cart service has multiple running Pods, requiring the session persistence feature to ensure that requests from the same user are routed to the same Pod and the user's cart information will not be lost. Session persistence is as shown below:


    Implement the session persistence feature by setting the DestinationRule loading balancing policy of the cart service, with UserID in the request header for consistent hashing.
    apiVersion: networking.istio.io/v1alpha3
    kind: DestinationRule
    name: cart
    namespace: base
    host: cart
    httpHeaderName: UserID
    - '*'
    After the configuration, click YOUR CART multiple times or ADD TO CART after login to call the cart service to verify whether requests from the same user are routed to the same Pod. The name of the Pod providing the cart service can be viewed in the bottom-left floating window, which is the same for requests from the same user. Requests from the same user are load balanced to the same Pod as shown below:
