Docker容器安装在var下，如何清理空间

1. 查看运行中的容器及名称

docker ps -a cd /var/lib/docker/overlay

2. 找到容器名称与overlay的对应关系

docker inspect lgd-operation-koa(容器名称) |grep /var/lib/docker/overlay/ du -sh * |grep 02c200054f955f7eb8cf91689828accca041b1b56321351a3c (查看对应的容器占用/var 目录大小) bug-management-server 411M abf51bebb82cc16fbd6fbabe3f005ac lgd-operation-koa 407M 02c200054f955f7eb8cf91689828accca041b1b56321351a3c lgd-operation-etl 411M 525307ea2aedf148ac7a142adc440 lgd-risk-koa 427M 4352941ee71f8c11fc7c5683793bba195a29 lgd-screen-koa 406M bea8e432ab67a9f0044e417a75ec15 ecp-resource-koa 1.3G f4e441fc16b63971cd2b5e584e6e 6690端口，查看91.139的nginx配置，里面nginx配置后端的6690 PC的 CSZX 637M 9d1f38b7da075886e5d01b722700da52a1c9729301eeb32 ecp-workload-koa 450M 992f80dff045f922404c77a0 isee-server 434M 3f98920c07f7e90c3bdad34460fbfa1f29a6 lgd-people-certification-koa 406M 18fa94503bfe74993032df25e86b7e9f6e42e974e0cf8deab lgd-risk-inspec-koa 411M 5b66f515879935ed0eecbbe2a5cb9e80ec7482 redis-server 97M 4e0a66fb0b7b7038362e7ed7e39c0b lgd-heartbeat-risk 14M 93697526f5da19cde0a5d5c1084 netcore-cookie 450M fed0c7cdefa83cd590aacb864c5f1dce003085253365d node-pps-upload 276M 95bf77f079e0ecd31aacadbebebdfb5326d658096201c52 node-libreoffice-convert 1.7G 9f3557be8d58779c21e6c4d7f3c697b445c2f549

3. 找最大的几个容器属主确认可清理文件范围

[root@azure-delivery tmp]# pwd /var/lib/docker/overlay/f4e441fc16b63971cd2b5e584e6e6b052548a324c5b560e04ea35e66b1b28a90/merged/tmp

/var/lib/docker/overlay/f4e441fc16b63971cd2b5e584e6e6b052548a324c5b560e04ea35e66b1b28a90/upper/tmp [root@azure-delivery tmp]# ll -lrt
