Use the proxy mode of WARP

Note

This article is based on the current WARP documentation, and the WARP commands may be changed by Cloudflare in the future. If you encounter any issues during following the instructions, please open an issue.

Warning

UDP support is not available in the proxy mode of WARP.

Use docker exec -it warp bash to get into the container and run the following commands:

warp-cli mode proxy
warp-cli proxy port 40000

Create a new healthcheck script new-healthcheck.sh with content:

#!/bin/bash

curl -fsS --socks5-hostname 127.0.0.1:1080 "https://cloudflare.com/cdn-cgi/trace" | grep -qE "warp=(plus|on)" || exit 1
exit 0

Update the docker-compose.yml file:

1. set env GOST_ARGS to -L :1080 -F=127.0.0.1:40000
2. mount new healthcheck to /healthcheck/connected-to-warp.sh:

For example, the default docker-compose.yml file will be changed to:

version: "3"

services:
  warp:
    image: caomingjun/warp
    container_name: warp
    restart: always
    # add removed rule back (https://github.com/opencontainers/runc/pull/3468)
    device_cgroup_rules:
      - 'c 10:200 rwm'
    ports:
      - "1080:1080"
    environment:
      - WARP_SLEEP=2
      - GOST_ARGS=-L :1080 -F=127.0.0.1:40000
      # - WARP_LICENSE_KEY= # optional
    cap_add:
      # Docker already have them, these are for podman users
      - MKNOD
      - AUDIT_WRITE
      # additional required cap for warp, both for podman and docker
      - NET_ADMIN
    sysctls:
      - net.ipv6.conf.all.disable_ipv6=0
      - net.ipv4.conf.all.src_valid_mark=1
    volumes:
      - ./data:/var/lib/cloudflare-warp
      - ./new-healthcheck.sh:/healthcheck/connected-to-warp.sh

After updating the docker-compose.yml file, run docker-compose down && docker-compose up -d to restart the container.
