#创建Glance数据库、用户、认证，前面已设置

# keystone上服务注册 ,创建glance服务实体,API端点（公有、私有、admin）

#镜像测试,下载有时很慢
wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img #下载测试镜像源
#使用qcow2磁盘格式，bare容器格式,上传镜像到镜像服务并设置公共可见
source ./admin-openstack.sh
openstack image create "cirros"   --file cirros-0.3.5-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public

#检查是否上传成功
openstack image list
#glance image-list
ls $Imgdir

#删除镜像 glance image-delete 镜像id
