One-Command Docker Setup for Chinese Servers: Fast, Secure, Mirror‑Optimized

In the previous articles the author introduced a Docker‑based personal music library and a remote‑work solution. This article provides a ready‑to‑use docker‑compose.yml file but many users get stuck at the first step: installing Docker, which can be cumbersome and slow in China due to network restrictions.

What the Script Does

Automatic OS detection – supports Rocky Linux, CentOS, RHEL, AlmaLinux (8/9); other systems abort with an error.

Installs Docker CE from Alibaba Cloud mirrors – avoids the timeout of official mirrors and speeds up download by more than five times.

Configures three domestic registry accelerators – adds https://docker.1ms.run, https://hub.rat.dev, and https://docker.xuanyuan.me to /etc/docker/daemon.json, any of which can accelerate docker pull.

One‑line, fully automated execution .

Quick Start: Single Command

Run the following as root or with sudo:

curl -fsSL https://download.xlsys.cn/tools/Shell/install-docker.sh | sudo bash

Optional: Download First for Security Concerns

curl -fsSL https://download.xlsys.cn/tools/Shell/install-docker.sh -o install-docker.sh
sudo bash install-docker.sh

Verify Installation

# Verify Docker
docker run --rm hello-world

# Verify Compose (example)
mkdir test-compose && cd test-compose
cat > docker-compose.yml <<EOF
version: "3"
services:
  app:
    image: louislam/uptime-kuma:1
    container_name: uptime-kuma
    restart: "always"
    volumes:
      - /etc/localtime:/etc/localtime
      - /run/docker.sock:/run/docker.sock
      - /sj-data/web/uptime:/app/data
    ports:
      - "3001:3001"
EOF
docker compose up -d

Manual Checks

# Docker version
docker --version
# Compose V2 status
docker compose version
# Registry mirrors loaded
docker info | grep -A 3 "Registry Mirrors"

What the Script Modifies

It adds a Docker repository to /etc/yum.repos.d/, creates or overwrites /etc/docker/daemon.json, and enables and starts the Docker service.

Final Thoughts

Docker itself is straightforward; the real challenges are network restrictions, environment differences, and configuration omissions. This script aims to eliminate those hassles, turning a complex setup into a routine task.
