node-exporter doesn't capture network traffic about swarmprom HOT 2 CLOSED

node-exporter must be run in privileged mode.
You can't do it in the compose file for swarm stack.
But you can change your compose file like this:

  node-exporter:
    image: stefanprodan/swarmprom-node-exporter:v0.16.0
    networks:
      - net
    user: <user>:<gid> # required when running in a swarm without sudo - use the <gid> of docker group of swarm

ex. user: root:0

from swarmprom.

I did a workaround involving running the container using the host network then using socat sidecar container to expose the node-exporter port in the docker network.

Now i just connect to the socat container instead of the node-exporter one.

  node-exporter-proxy:
    image: alpine/socat:latest
    command: tcp-listen:9100,fork,reuseaddr tcp-connect:172.18.0.1:9100
    networks:
      - net

from swarmprom.
