i was having similar issue

can you go into prometheus container with docker-compose exec prometheus sh
and then run ping node-exporter?

You should see something like:

/prometheus $ ping node-exporter
PING node-exporter (192.168.224.3): 56 data bytes
ping: permission denied (are you root?)

If you are not seeing an IP like in the example above. Please check if your docker-compose prometheus service has "node-exporter" defined in links:

and also try to use the default network instead of the configured.

ping node-exporter

Thanks for replying. From within the container, the Ip is reachable, however, no data could be got.

/prometheus $ ping node-exporter
PING node-exporter (172.26.0.2): 56 data bytes
ping: permission denied (are you root?)
/prometheus $

Because you need to add -u 0 to docker-compose exec to be able to run ping.

I had the same issue, the fix was easy, I changed prometheus/prometheus.yml.
I removed this piece:

dns_sd_configs:
    - names:
      - 'tasks.cadvisor'
      type: 'A'
      port: 8100

and added (actually, uncommented) this piece:

static_configs:
    - targets: ['cadvisor:8080']

I guess there is some issue with name resolving, so I just explicitly put cadvisor container name and its port.
