Using SOCKS5 with Watchtower

To use a proxy with Watchtower, you need to perform additional configuration similar to the configuration for Docker. Instead of JSON file parameters, they are set in the environment variables HTTPS_PROXY and NO_PROXY.

Example Compose file:

services:
  watchtower:
    image: containrrr/watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      HTTPS_PROXY: "socks5://proxy.huecker.io:443"
      NO_PROXY: "ghcr.io"
