If your ingress not used session sticky, please refer to the configuration below.

global params description example required
sls.project The project name of a SLS instance. k8s-log-c550367cdf1e84dfabab013b277cc6bc2" True
sls.logstore The specific logStore of a SLS project. nginx-ingress True
sls.ingress.route route of ingress(namespace-svc-port) default-kubecon-springboot-demo-6666 True
