1. 在执行
docker build . --no-cache -t xxx
命令时，报
Error parsing reference: "xxx/ubuntu20.04:117486 AS build" is not a valid repository/tag: invalid reference format
2. 分析，这个xxx/ubuntu20.04:117486 中并没有大写字符，因此排查是docker image 大小写
3. 查看docker version
[root@push26 mdc-ecdn-monitor]# docker --version
Docker version 1.13.1, build 7d71120/1.13.1
证明确实是版本太低
4. 解决步骤：
卸载旧版本：
yum -y remove docker*
安装依赖包
[root@push26 mdc-ecdn-monitor]# sudo yum install -y yum-utils
