やること
microstackを使ってAWS上のubuntu20.04上にopenstackを構築する
手順
AWSでubuntu20.04のVMを作成する
microstackのrequirementsを見る
memory 16G, disk 50Gが必要
Ref: https://ubuntu.com/openstack/install
リソースを割り当ててVMを起動
注意
自分のlocalマシンのsshの公開鍵を登録してVMを起動することを忘れずに。これを忘れると作ったVMにsshアクセスできない。画面省略。
作られたVMへsshアクセス
bash
# xxx.xxx.xxx.xxxはVMに自動的に割り当てられたパブリックIPv4アドレスを指0900定
$ ssh xxx.xxx.xxx.xxx -l ubuntu
snapでmicrostackをinstall
Ref: https://ubuntu.com/openstack/install の2
bash
$ sudo snap install microstack --beta --devmode
microstack (beta) ussuri from Canonical✓ installed
microstackを初期化
Ref: https://ubuntu.com/openstack/install の3
bash
$ sudo microstack init --auto --control
...
2021-05-11 04:47:34,227 - microstack_init - INFO - Complete. Marked microstack as initialized!
VMのsecurity groupにhttpアクセスをinboundで追加
これで自分のlocalマシンからVM(OpenStackのhorizon)へhttpアクセスできるようになる。
httpでhorizonにアクセスしてみる
horizonにloginする時のpasswordは以下のコマンドで取得できる
bash
$ sudo snap get microstack config.credentials.keystone-password
その上でhttp://[VMのパブリックIPv4アドレス]でhorizonにアクセスできる。
sshの鍵をopenstackに登録
bash
# openstackをinstallしたubuntu20.04マシンにて
$ ssh-keygen
このあたりからkeyを登録
OpenStack上からVMを作成してみる
oepnstackコマンドからVMを作ってみる
microstack.openstackをopenstackで実行できるようにする
Ref: https://tech.virtualtech.jp/entry/2019/12/17/113221
bash
$ sudo snap alias microstack.openstack openstack
VMを作成
bash
