关于centos docker版本过低导致 is not a valid repository/tag: invalid reference format

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 format2. 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 --versionDocker 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-utilsLoaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-managerThis system is not registered with an entitlement server.
