本文主要介绍如何使用glance命令上传镜像

1.选项 Optional arguments: --architecture Operating system architecture as specified in http://docs.openstack.org/trunk/openstack- compute/admin/content/adding-images.html --protected [True|False] If true, image will not be deletable. --name Descriptive name for the image --instance-uuid Metadata which can be used to record which instance this image is associated with. (Informational only, does not create an instance snapshot.) --min-disk Amount of disk space (in GB) required to boot image. --visibility Scope of image accessibility Valid values: public, private --kernel-id ID of image stored in Glance that should be used as the kernel when booting an AMI-style image. --tags [ ...] List of strings related to the image Operating system version as specified by the distributor --disk-format Format of the disk Valid values: ami, ari, aki, vhd, vmdk, raw, qcow2, vdi, iso Common name of operating system distribution as specified in http://docs.openstack.org/trunk /openstack-compute/admin/content/adding-images.html --id An identifier for the image --owner Owner of the image --ramdisk-id ID of image stored in Glance that should be used as the ramdisk when booting an AMI-style image. --min-ram Amount of ram (in MB) required to boot image. --container-format Format of the container Valid values: ami, ari, aki, bare, ovf, ova, docker --property Arbitrary property to associate with image. May be used multiple times. --file Local file that contains disk image to be uploaded during creation. Alternatively, the image data can be passed to the client via stdin. --progress Show upload progress bar. 1.1部分选项翻译 –architecture 指定操作系统架构–protected 如果为True，镜像将不可删除–name 指定镜像名称–min-disk 启动镜像所需的最小的磁盘空间(以GB为单位)–min-ram 启动镜像所需的最小内存大小(以MB为单位)–id 镜像的ID–owner 镜像的所有者–disk-format 指定镜像的格式（ami, ari, aki, vhd，vmdk, raw, qcow2, vdi, iso）–file 指定镜像文件–container 指定容器格式（ami, ari, aki,bare, ovf, ova, docker）----visibility 镜像的可见范围（public,private）或?? --public & --private & --is-public=True–progress 进度显示上传进度条 2.创建镜像 2.1创建一个Centos镜像 [root@controller ~]# glance image-create --name centos7.2 --disk-format qcow2 --container bare --file /opt/iaas/images/CentOS_7.2_x86_64_XD.qcow2 +------------------+--------------------------------------+ | Property | Value | +------------------+--------------------------------------+ | checksum | ea197f4c679b8e1ce34c0aa70ae2a94a | | container_format | bare | | created_at | 2019-10-08T19:51:27Z | | disk_format | qcow2 | | id | d1bf479f-d82a-4be3-8af4-6c0586f12f5e | | min_disk | 0 | | min_ram | 0 | | name | centos7.2 | | owner | 76a36b75f7124d26871eaf6977f4a3ba | | protected | False | | size | 400752640 | | status | active | | tags | [] | | updated_at | 2019-10-08T19:51:33Z | | virtual_size | None | | visibility | private | +------------------+--------------------------------------+ 2.2注意事项命令中加粗的为必选项 glance image-create --name centos7.2 \ –disk-format qcow2 --container bare --file 镜像文件要注意身份验证问题，否则容易出现下列问题 [root@controller ~]# glance image-list You must provide a username via either --os-username or env[OS_USERNAME]

需要加载用户身份变量，执行以下代码

export OS_PROJECT_DOMAIN_NAME=demo export OS_USER_DOMAIN_NAME=demo export OS_PROJECT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=000000 #此处以实际密码为准 export OS_AUTH_URL=http://controller:35357/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2

或者将以上代码保存到一个以 .sh （这里我保存在/etc/keystone/admin-openrc.sh 这个文件中）结尾的文件中然后执行下方操作

[root@controller ~]# source /etc/keystone/admin-openrc.sh [root@controller ~]# glance image-list +--------------------------------------+-----------+ | ID | Name | +--------------------------------------+-----------+ | d1bf479f-d82a-4be3-8af4-6c0586f12f5e | centos7.2 | +--------------------------------------+-----------+
