今回、Debian OS は debian.org より、qcow2 イメージをダウンロードして 使用します
Debian OS のインスタンスを起動するための大まかな手順は次となります。
① OSイメージダウンロード
② Oracle Cloud の Object Storage にqcow2イメージをUpload
③ qcow2イメージから Custom Imageを作成
④ Custom Imageから、インスタンス作成
#■ Debian OS インストール
##● qcow2イメージダウンロード
debian.org より、qcow2 イメージをダウンロード
・Debian qcow2イメージ
http://cdimage.debian.org/cdimage/openstack
##●Object Storage にqcow2イメージをUploadしてCustome Image作成
① Bucket作成
・qcow2イメージをUpload するためのObject Storage を作成
② 作成したObject Storageにqcow2イメージをUpload
③ Pre-Authenticated Request(PAR)作成
Object Storageへ URLアクセスするための PARを作成
・Upload したファイルの右側にある [・・・]ボタンから [Create Pre-Authenticated Request]をクリック
・NAMEを設定して[Create Pre-Authenticated Request]をクリック
・Details画面にある URL文字列 をコピーして[Close]をクリック
④ Custom Image 作成
・Compute Service 画面から、[Custom Image]をクリックし[Import Image]ボタンをクリック
- NAME：適切な名前を記入
- OPERATING SYSTEM：Linuxを選択
- OBJECT STORAGE URL：作成したPARのURLを記入
- IMAGE TYPE：QCOW2を選択
・作成完了すると以下画面のように ステータスが AVAILABLEとなる
##● Debian インスタンス作成
・作成したCustme Image からDebian Instance 作成
- NAME：適切な名前を記入
- IMAGE: 作成したCustome Image を選択
- SSH KEYS:OSアクセスするための SSH KEYを設定
・作成完了すると以下画面のようにステータスがRUNNINGとなる
##● DPDK用VNIC追加
・OCIコンソールからAttached VNICs画面にてDPDK用VNICを追加
