IP address changes on container restart

[mqt2r]

Every time I restart omniedge container, the IP address changes.

docker-compose file:

version: "2.1"
services:
  omniedge:
    image: omniedge/omniedge:latest
    container_name: omniedge
    hostname: fixedname
    privileged: true
    network_mode: host
    restart: unless-stopped
    environment:
      - OMNIEDGE_SECURITYKEY=xxxx
      - OMNIEDGE_VIRUTALNETWORK_ID=xxxx
    volumes:
      - /dev/net/tun:/dev/net/tun
    cap_add:
      - net_admin

I expect the IP address of the container to remain the same after a restart.

The problem is from the command cp /proc/sys/kernel/random/uuid /etc/machine-id, which will generate new uuid after a restart. You can change your dockerfile and change it to a fixed uuid. Here is the script： https://github.com/omniedgeio/omniedge-docker/blob/main/entrypoint
