I have a docker-compose and both nginx and nginx-prometheus-exporter are containers. I put the relevant parts here:
nginx:
container_name: nginx
image: nginx:1.19.3
restart: always
ports:
- 80:80
- 443:443
- "127.0.0.1:8080:8080"
nginx-exporter:
image: nginx/nginx-prometheus-exporter:0.8.0
command:
-nginx.scrape-uri
-http://127.0.0.1:8080/stub_status
I tried http://nginx:8080/stub_status,
nginx:8080/stub_status and
127.0.0.1:8080/stub_status for -nginx.scrape-uri but none of them worked and I got Could not create Nginx Client: failed to get http://127.0.0.1:8080/stub_status: Get "http://127.0.0.1:8080/stub_status": dial tcp 127.0.0.1:8080: connect: connection refused.
Also the localhost:8080/stub_status is available in my VM using curl.
the problem was the missing -.
