Dockerfile.rabbitmq

FROM rabbitmq:3.13-management

# 安装 wget 用于下载插件
RUN apt-get update && apt-get install -y wget

# 下载 rabbitmq_delayed_message_exchange 插件
RUN wget -P /plugins https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v3.13.0/rabbitmq_delayed_message_exchange-3.13.0.ez

# 启用插件
RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange

使用docker compose up --build -d构建报错：

mth@vm001:~/workspace/payment-service$ docker compose up --build -d
Compose now can delegate build to bake for better performances
Just set COMPOSE_BAKE=true

问题是 Docker 容器在构建阶段无法解析域名（DNS 解析失败），即便宿主机本身网络没问题。这是个非常常见的 Docker DNS 问题，尤其在公司内网、CI/CD、或海外镜像不通时。

解决：

编辑或创建文件 sudo vim /etc/docker/daemon.json：

{
  "dns": ["8.8.8.8", "8.8.4.4"]
}


#############
国内建议：
{
  "dns": ["223.5.5.5", "8.8.8.8"]
}

3. 重启 Docker 服务

sudo systemctl daemon-reexec

sudo systemctl restart docker
