查看磁盘空间

df -h

/目录占用达到100%, 剖析可能是docker容器数据占用了空间

去container目录查看占用状况

cd /var/lib/docker/containers
du -sh {目录}查看哪个目录有占用空间异样， 删除对应文件即可

如我这里是Gitlab日志文件占用了27G：

# 删除Gitlab日志文件并重启Gitlab容器即可"LogPath": "/var/lib/docker/containers/f16aa2f0c73a6093b482fc3694119a1b753773fde92f797e8b79e86326515ca3/f16aa2f0c73a6093b482fc3694119a1b753773fde92f797e8b79e86326515ca3-json.log"

Tips: 查看容器详细信息命令

docker container inspect {容器名}
示例

docker container inspect gitlab
