Description

To prevent these issues:

  1. Verify VMware Host Placement: Ensure that all SCG instances within the cluster are deployed on the same VMware host.

Placing all instances on the same host helps stabilize the cluster services, allowing the instances to recognize each other and function as expected in the cluster.

Issue/Introduction

When setting up multiple SCG (Scout Cloud Gateway) instances in a cluster, you may encounter the following problems, even if the instances are on the same network and are able to ping each other:

  • The scg-controller and scg-mongo-controller services fail to start, entering a continuous restart loop.
  • The second SCG instance does not appear in the gateway view.

These issues may occur if the SCG instances are not hosted on the same VMware host, despite their network configurations appearing correct.

Additional Information

Deploying SCG instances on the same VMware host can resolve service startup issues and ensure all instances appear correctly within the gateway view. This setup is essential for stable SCG cluster operation.
