1. 在執行

docker build . --no-cache -t xxx

命令時，報

Error parsing reference: "xxx/ubuntu20.04:117486 AS build" is not a valid repository/tag: invalid reference format

2. 分析，這個xxx/ubuntu20.04:117486 中并沒有大寫字符，因此排查是docker image 大小寫

3. 查看docker version

[root@push26 mdc-ecdn-monitor]# docker --version Docker version 1.13.1, build 7d71120/1.13.1

證明確實是版本太低

4. 解決步驟：

卸載舊版本：

yum -y remove docker*
