02/17/2023, 3:17 PMThat is the log of the frontend
Jose Infazon
02/17/2023, 3:17 PMand it is solved if I restart the container

02/17/2023, 3:21 PMThat
Not foundj
Jose Infazon
02/17/2023, 3:22 PMbut all the services are up...actually it solves when I only restart the frontend container...so there is my question if I need to add a "depends-on"

Prashant Shahi
02/17/2023, 3:24 PMThat should already be set to alertmanager and query-service.
Prashant Shahi
02/17/2023, 3:29 PMI suppose this issue is happening because query-service got new internal IP assigned while Nginx in frontend is trying to connect to prior internal IP since, it previously was resolve to it.
Prashant Shahi
02/17/2023, 3:29 PMTo verify that, check the internal IP of query-service and the one from frontend logs:
Copy code
docker inspect $(docker ps -q ) \
--format='{{ printf "%-50s" .Name}} {{range .NetworkSettings.Networks}}{{.IPAddress}} {{end}}'Prashant Shahi
