Belajar Linux ID – Pada tutorial kali ini kita akan mencoba mempelajari command line yang ada di openstack, disini kita akan memulai mencoba membuat image via CLI (Command Line Interface).
Sebenarnya untuk membuat image di openstack juga dapat melalui dashboard openstack atau sering disebut Horizon.
Namun tidak ada salah nya kita mengetahui 2 cara baik melalui CLI ataupun Horizon, untuk cara membuat image melaui horizon Anda dapat melihatnya pada link berikut: Openstack: Upload Image atau ISO
Berikut tahapan – tahapannya:
Silakan login ke Openstack controller Anda, dan login ke RC Admin atau keystonerc_admin yang berada di _ /root _.

[root@hamim-controller ~]# source keystonerc_admin
Untuk melihat tabel image di openstack jalankan perintah berikut

Disini kami coba mengunggah kembali image cirros menggunakan wget seperti berikut

[root@hamim-controller ~(keystone_admin)]#
[root@hamim-controller ~(keystone_admin)]# wget -c https://download.cirros-cloud.net/0.5.1/cirros-0.5.1-x86_64-disk.img
Create image cirros dengan memberi nama image menjadi cirros1
