* Glance 설치는 Controller 노드에서 진행합니다.
1. 데이터 베이스 생성
Glance DB 패스워드 생성 시, 특수문자가 인식을 못하는 경우가 있으므로, 특수문자를 제외하고 만드시길 바랍니다.

2. Glance 사용자, 서비스, 엔드포인트 생성하기
admin 환경으로 변경합니다.
root@controller:~# source admin-openrc
glance 사용자를 생성합니다.
admin 정책에 glance 사용자를 추가해줍니다.
root@controller:~# openstack user create --domain default --password GLANCE_PASS glance
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | c30fa99748de4afe97ec6c8307e3f6f6 |
| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
root@controller:~# openstack role add --project service --user glance admin
service glance를 생성해줍니다.
root@controller:~# openstack service create --name glance --description 'OpenStack Image' image
+-------------+----------------------------------+

+-------------+----------------------------------+
image 서비스를 사용할 endpoint를 생성해줍니다. public, internal, admin 환경 3군데 진행해줍니다.
root@controller:~# openstack endpoint create --region Region01 image public http://controller:9292
+--------------+----------------------------------+

+--------------+----------------------------------+
서비스가 생성된 것을 확인합니다.
root@controller:~# openstack service list

3. 방화벽
tcp/9292 포트를 열어줍니다 (glance-api)
tcp/9191 포트를 열어줍니다. (glance-registry)
4. 패키지 설치하기
root@controller:~# apt-get install glance -y
5. 설정파일 수정하기
glance-api.conf 파일은 Glance 서비스가 클라이언트로부터 API 요청을 받아들이기 위해 사용됩니다.
root@controller:~# cat /etc/glance/glance-api.conf
[DEFAULT]
show_image_direct_url = True
[database]
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
backend = sqlalchemy
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = GLANCE_PASS
[paste_deploy]
flavor = keystone
[glance_store]
stores = file,http default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[image_format]
disk_formats = ami,ari,aki,vhd,vhdx,vmdk,raw,qcow2,vdi,iso,ploop.root-tar
root@controller:~# chmod 640 /etc/glance/glance-api.conf
root@controller:~# chown root:glance /etc/glance/glance-api.conf
glance 관리명령어 glance-mange를 통해 glance 데이터베이스에 필요한 테이블을 생성합니다.
root@controller:~# su -s /bin/bash glance -c "glance-manage db_sync"
6. 서비스 시작하기
glance-api 서비스를 시작해줍니다.
root@controller:~# systemctl restart glance-api
glance-registry 서비스 포트 : 9191
glance-api 서비스 포트 : 9292
7. 검증하는 방법
admin 환경으로 들어가서 cirros OS 이미지를 다운받습니다.
다운받은 뒤, 해당 이미지로 생성합니다.
root@controller:~# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
root@controller:~# openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public
