How to restrict access to a docker container?

Question

linux

The collection of metrics occurs through the node-exporter, which runs in a container.
I tried adding a rule to the docker and docker-user chain, but the container is still available to everyone.
How to restrict access to the container?

Answer 1

What does "restrict access" mean? If you mean that there is access to the port (what is it, 9100?)? then your container is probably started with --network=host and this port is open on all interfaces of the host machine.
In general, it is not very clear what the problem is and what needs to be solved.
