物理删除harbor中不要的镜像
在harbor的UI端删除镜像的操作是逻辑删除的,需要物理删除不要的镜像达到释放空间的目的,是需要将harbor停下来再删除的。
步骤如下：
查看harbor相关镜像的名称
[root@master harbor]# docker images

注意:我们接下来将用到的镜像是vmware/registry-photon:v2.6.2-v1.5.0
停止harbor
[root@master harbor]# docker-compose stop
Stopping nginx ... done
Stopping harbor-jobservice ... done
Stopping harbor-ui ... done
Stopping registry ... done
Stopping harbor-adminserver ... done
Stopping harbor-db ... done
Stopping redis ... done
Stopping harbor-log ... done
物理删除
docker run -it --name gc --rm --volumes-from registry vmware/registry-photon:v2.6.2-v1.5.0 garbage-collect /etc/registry/config.yml
注意,如果只想看下会删除哪些镜像而不是真正的去删除,则需要加上选项--dry-run
如下:
docker run -it --name gc --rm --volumes-from registry vmware/registry-photon:v2.6.2-v1.5.0 garbage-collect --dry-run /etc/registry/config.yml
启动harbor
[root@master harbor]# docker-compose up -d

再次查看空间
df -h /harbor的初始化目录
