To run a Go Simple Tunnel (GOST) through Cloudflare WARP on Docker, use a docker-compose.yml similar to the one provided below.

Bring it up with a standard docker-compose up -d command.

version: '3'

x-socks-base: &socks-base
  image: threatpatrols/cfwarp-gost:latest
  restart: always
  cap_add:
    - NET_ADMIN
  sysctls:
    - net.ipv6.conf.all.disable_ipv6=0
    - net.ipv4.conf.all.src_valid_mark=1

services:

  socks-cloudflare-local:
    <<: *socks-base
    container_name: socks-cloudflare-local
    ports:
      - '127.0.0.1:1080:1080'

  socks-with-upstream:
    <<: *socks-base
    container_name: socks-with-upstream
    ports:
      - '127.0.0.1:1081:1080'
    environment:
      - GOST_FORWARD=socks5://<socks-server-ip-address>:<socks-server-port>

• This sample docker-compose.yml should be modified to suit your situation.
• The socks-with-upstream section is optional, you can use a GOST SOCKS5 tunnel through Cloudflare WARP without an upstream proxy.
• If you plan to use the socks-with-upstream definition, pay attention to the GOST_FORWARD environment variable
• Credentials can be added for the upstream-proxy using standard socks5://<username>:<password>@<socks-server-ip-address>:<socks-server-port> notation.
• This docker-compose.yml example uses YAML Anchors to make the service definitions shorter without repeating etc, learn more here if unfamiliar https://docs.docker.com/compose/compose-file/10-fragments/

Test the two docker containers once compose-up is done:

curl --socks5 127.0.0.1:1080 "https://ipinfo.io/json"
curl --socks5 127.0.0.1:1081 "https://ipinfo.io/json"

You can configure the container through the following environment variables:

• GOST_FORWARD: Provides the main purpose for this container by making it possible to easily express GOST configurations such that external traffic is automatically transported over a Cloudflare WARP tunnel.

• WARP_START_DELAY: The time to wait for the WARP daemon to start, in seconds. The default is 2 seconds. If the time is too short, it may cause the WARP daemon to not start before using the proxy, resulting in the proxy not working properly. If the time is too long, it may cause the container to take too long to start.

• WARP_LICENSE_KEY: The license key of the WARP client, which is optional. If you have subscribed to WARP+ service, you can fill in the key in this environment variable. If you have not subscribed to WARP+ service, you can ignore this environment variable.

Data persistence: Use the host volume ./data to persist the data of the WARP client. You can change the location of this directory or use other types of volumes. If you modify the WARP_LICENSE_KEY, please delete the ./data directory so that the client can re-detect and re-register again.

NB: early releases of this project mistakenly referred to "Cloudflare WARP" as "Cloudflared" - the project and repos have been renamed accordingly since.

This Docker is heavily based on the work from caomingjun that has an awesome blog post and github repo.
