docker-compose up 启动容器服务超时错误：ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.


由于docker-compose up 同时启动的服务过多，超过了请求HTTP限制的60s时间仍未全部成功启动起来，所以出现了超时错误：

    ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
               If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

其中60s是默认的时间。
解决思路：

把 COMPOSE_HTTP_TIMEOUT 的值调大，并转为环境变量即可。

解决步骤：

先进入/etc/profile配置文件，执行命令：

    vi /etc/profile

然后在尾部添加上下面代码：

    export COMPOSE_HTTP_TIMEOUT=500
    export DOCKER_CLIENT_TIMEOUT=500

接着使/etc/profile配置文件生效，执行命令：

    source /etc/profile

最后重新执行命令 docker-compose up 即可。
