5. glance 패키지 설치

# apt install glance

6. glance-api.conf 파일 설정

- [keystone_authtoken] 영역에 다른 설정이 존재한다면 주석처리하기

# vi /etc/glance/glance-api.conf

[database]
connection = mysql+pymysql://glance:openstack@controller/glance

[keystone_authtoken]
www_authenticate_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/

7. Database sync

# su -s /bin/sh -c "glance-manage db_sync" glance

8. glance service 재시작

# service glance-api restart

9. glance image생성

$ wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
$ glance image-create --name "cirros" \
  --file cirros-0.4.0-x86_64-disk.img \
