Use Cloudflared Docker to Map Your Sub Domain to Application in Free PaaS (Codesandbox.io)

Cloudflared docker has Cloudflare Tunnel client which can easily and securely exposes private services to public through the Cloudflare edge network. This blog post shows you how to deploy this Cloudflared docker into PaaS plaform such as Codesandbox.io to map your sub domain to the apps from private PaaS network to public.

With this Cloudfalred docker, You can then use it to expose:

Private HTTP-based services exposed on a public DNS hostname, optionally locked down by Cloudflare Access (see https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/⁠ and https://developers.cloudflare.com/cloudflare-one/applications/configure-apps/self-hosted-apps/⁠ )
Private networks accessed by TCP/UDP IP/port by WARP enrolled users, with a Zero Trust approach, to squash away your legacy VPN (see https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/private-net/⁠ )

Docker Hub Site: https://hub.docker.com/r/cloudflare/cloudflared

Github site: https://github.com/cloudflare/cloudflared

Note: Here is another way to map your domain to Codesandbox PaaS, which is to use vercel, as shown from github project: https://github.com/k0baya/reserve-vercel/.

Steps to Create a Cloudflared Docker with APP

1 Create your workspace box, either devbox or sandbox

2 Create Docker

You will be only able to select Devbox for this type of template:

3 Modify tasks.json file under workspace/.codesandbox

{
  // These tasks will run in order when initializing your CodeSandbox project.
  "setupTasks": [
    {
      "name": "Deploy",
      "command": "cd /project/workspace/.devcontainer/ && docker compose up -d"
    }
  ],

  // These tasks can be run from CodeSandbox. Running one will open a log in the app.
  "tasks": {
    "cloudflare": {
      "name": "cloudflare",
      "command": "cloudflare",
      "runAtStart": true
    }
  }
}

4 Create docker-compose.yaml file under workspace / .devcontainer

version: "2"
services:
  qinglong:
    image: whyour/qinglong:latest
    volumes:
      - /project/sandbox/ql/data:/ql/data
    ports:
      - "0.0.0.0:5700:5700"
    environment:
      QlBaseUrl: "/"
    restart: always

  cloudflared:
    restart: always
    network_mode: host
    environment:
      - tz=america/new_york
    command: tunnel --edge-ip-version auto --protocol quic --heartbeat-interval 10s run --token eyJhIjoiN2YzNjkyNmRlOTI3ZWQ3NmEwYThhOGYyNWFhZjMxOGMiLCJ0IjoiODQ3YzM3NTctODRhZC00YjExLTliNzAtMmNiZmUwZjgzYmNhIiwicyI6Ik1qTTJZekV5T1RndFkyVXdPQzAwWkRCaExUaGpZbVF0WkRVMk1ETTRNREl3TldSbSJ91
    container_name: cloudflared
    image: cloudflare/cloudflared:latest

Once you pressed ctrl+s to save docker-compose.yaml file, it will ask you to rebuild & restart the deccontainers.

Manual Running the docker if task does not work:

Open a shared Terminals

Run following commands:

cd /project/workspace/.devcontainer/ && docker compose up -d

Cloudflare

1. Create a tunnel in Zero Trust / Networks / Tunnels

2. Make sure you created your Public hostname to map to your Codesandbox app created in previous step:

3. Test the public domain

Docker Compose

Create docker-compose.yaml file under workspace / .devcontainer

HFS

Docker hub : https://hub.docker.com/r/rejetto/hfs

Github : https://github.com/rejetto/hfs

docker run -d -p 8080:8080 -e HFS_CREATE_ADMIN=password123 -e HFS_PORT=8080 rejetto/hfs:v0.53.0

services:
    hfs:
        ports:
            - 8080:8080
        environment:
            - HFS_CREATE_ADMIN=password123
            - HFS_PORT=8080
        image: rejetto/hfs:v0.53.0

You might want to mount your own configuration file folder and file folder into the docker-compose.yaml file configuraiton.

With Cloudflared

services:
    hfs:
        ports:
            - 8080:8080
        environment:
            - HFS_CREATE_ADMIN=password123
            - HFS_PORT=8080
        image: rejetto/hfs:v0.53.0

    cloudflared:
        restart: always
        network_mode: host
        environment:

        container_name: cloudflared
        image: cloudflare/cloudflared:latest

If add following code into docker-compose.yaml file, it wont work properly:

volumes:
- ./hfsconf:/home/hfs/.hfs # for hfs conf persistence
- ./myDisk:/app/myDisk # for your files
# don't forget to share volumes to access certificate files

Baota_Panel

端口 8888 为面板，2022 为 SSH 端口，2021 为 FTP 端口，2080 和 2443 为网页服务预留端口，2888 是官方给的，不知道作用。
