Docker拉取镜像错误Error response from daemon: manifest for filerun/filerun:latest not found: manifest unknown: manifest unknown

## Ubuntu更新怎么都不能拉取镜像，安装filerun提示错误

Error response from daemon: manifest for filerun/filerun:latest not found: manifest unknown: manifest unknown```

看了官方的Docker-compose才知道，pull镜像没有版本号的原因

image: filerun/filerun:8.1  加个版本号解决问题
