1. 在执行
docker build . --no-cache -t xxx
- 1.
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
[[email protected] mdc-ecdn-monitor]# docker --version
Docker version 1.13.1, build 7d71120/1.13.1
- 1.
- 2.
证明确实是版本太低
4. 解决步骤：
卸载旧版本：
yum -y remove docker*
- 1.
安装依赖包
[[email protected] mdc-ecdn-monitor]# sudo yum install -y yum-utils
