Error nginx load-balance rancher - ha

Archive Rancher 1.x

As we talked I changed my topology replacing the BIG IP by NGINX to the load-balance between Rancher hosts.

In this new topology I’m having trouble on the “Stacks” with this state of “Degraded” and “initializing”.

Thank you for the response.

Yes as you said I used the rancher documentation in order to configure NGINX.

But I’m still having trouble on go-machine-service and rancher-compose-executor with the state of “Degraded” and “initializing”.

Do you still have this kind of status ?

regards,
Marc
