OpenStack镜像服务基本操作

 查询Glance服务状态

#glance-control all status

[root@controller ~]# glance-control all status
glance-api (pid 2074) is running...
glance-registry (pid 2344) is running...
glance-scrubber is stopped

查询glance-api版本

# glance-api --version

[root@controller ~]# glance-api --version
2014.1.3

查询glance-control版本

# glance-control --version

[root@controller ~]# glance-control --version
2014.1.3

下面的命令作用是启动相关服务，并设置为开机启动。

# service openstack-glance-api start

# service openstack-glance-registry start

# chkconfig openstack-glance-api on

# chkconfig openstack-glance-registry on

下载CirrOS镜像文件

# mkdir /tmp/images

# cd /tmp/images/

# wget http://download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-disk.img

查看文件信息

# file cirros-0.3.4-x86_64-disk.img

[root@controller ~]# file cirros-0.3.4-x86_64-disk.img
cirros-0.3.4-x86_64-disk.img: Qemu Image, Format: Qcow , Version: 2

使用命令行创建镜像

# glance image-create --name "cirros-0.3.4-x86_64-disk" --disk-format qcow2 --container-format bare --is-public True --progress < cirros-0.3.4-x86_64-disk.img

[root@controller ~]# glance image-create --name "cirros-0.3.4-x86_64-disk" --disk-format qcow2 --container-format bare --is-public True --progress < cirros-0.3.4-x86_64-disk.img
