[Bug] linkis on k8s is not successful

Start by reproducing the linkis-dist deployment with helm install linkis . -n test on Linkis 1.3.2, then inspect the mg-eureka and mg-gateway logs for service-discovery and startup-order failures. Trace the internal service dependencies involved in the reported UnknownHostException and connection refusal; done means the Helm deployment starts services in a usable dependency order without these errors.

Expected behavior

Because there are dependencies within the internal sub services of Linkis, we hope to resolve the dependency order

Your environment

Linkis version used: 1.3.2
openjdk version: 1.8.0_332
centos7
