大家好，
我正在嘗試在我的 TS-264 上設置多個容器，最初使用 Docker Compose，但沒有成功。所以我改用更簡單的純 Docker，但也失敗了。
最終，我需要運行 4 個容器，並且它們能夠彼此通信。計劃如下：
- 3 個容器在 ipvlan 網路上。
- 1 個容器採用 host 模式（因為它需要存取 USB 埠）。
為了測試方便，我寫了一個簡單的腳本，拉取並運行一個 Alpine 容器。
以下是我的腳本：
#!/bin/sh
# 1. 移除所有
docker network rm qnap-ipvlan 2>/dev/null || true
docker rm -f alpine 2>/dev/null || true
# 2. 建立 ipvlan 網路（L2 模式）
# docker network create -d ipvlan --subnet=10.159.2.0/24 --gateway=10.159.2.4 --ip-range=10.159.2.96/28 -o parent=eth1 -o ipvlan_mode=l2 qnap-ipvlan
docker network create -d ipvlan --subnet=10.159.2.0/24 --gateway=10.159.2.4 --ip-range=10.159.2.96/28 -o parent=eth1 -o ipvlan_mode=l2 -o ipvlan_flags=bridge -o com.docker.network.driver.mtu=1500 qnap-ipvlan
# 3. 檢查是否成功
docker network inspect qnap-ipvlan
# 4. 用 alpine 容器測試
docker run -it --rm --network=qnap-ipvlan --ip=10.159.2.109 alpine sh -c "ping -c 2 10.159.2.4 && ping -c 2 10.159.2.10"
# 5. Alpine 是否可達
# 從 QNAP 本機：
curl -I http://10.159.2.109 2>/dev/null || echo "Testing connection"
# 6. 狀態
docker-compose ps
docker network inspect qnap-ipvlan
這是我得到的結果/錯誤：
[/share/Container/docker-compose] # chmod ug+x ./setup_IPvlan_alpine.sh
[/share/Container/docker-compose] # ./setup_IPvlan_alpine.sh
qnap-ipvlan

我遇到的主要錯誤是：
“docker: Error response from daemon: failed to create the ipvlan port: device or resource busy.”
為什麼會出現這個 “device or resource busy” 的 ipvlan 錯誤？我要怎麼修正才能繼續設置？
任何建議或意見都非常感謝
先謝謝大家！
