When I access Prometheus targets, one of these targets is getting "state down", even thoug I can access it on my browser (
). I am problably missing something. I´d like to know what it is, because I have searched for it for some hours and I can´t find the reason. I even disabled the Windows firewall for a while, but it doesn´t work.
I am using docker and Spring. The Rest services I created are working fine.
My docker is configurated as shown bellow.
docker-compose.yml
Use root/example as user/password credentials

prometheus.yml:

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:

Accessing http://myIp:8080/actuator/prometheus I get the following:
