背景と目的
Ubuntu Pro が Personal Use で 5 台まで無料で使えるようになりました。バージョンアップせずに延命できる選択肢として、Azure で使っている Ubuntu 18.04 LTS を Personal Use で Pro にして 2023 年の EOL を 2028 年まで延ばす検証をしてみました。
検証用の仮想マシンを作成
bash
# 環境変数をセットします
region=japaneast
prefix=mnrubpro
# リソースグループを作成します
az group create \
--name ${prefix}-rg \
--location $region
# 仮想マシンを作成します
az vm create \
--resource-group ${prefix}-rg \
--name ${prefix}-vm \
--os-disk-name ${prefix}-vmOSDisk \
--image Canonical:UbuntuServer:18.04-LTS:latest \
--size Standard_B1s \
--admin-username azureuser \
--generate-ssh-keys \
--nsg-rule NONE \
--public-ip-address-dns-name ${prefix}
# 自分の IP から SSH 接続できるようにします
az network nsg rule create \
--resource-group ${prefix}-rg \
--name Allow-SSH \
--nsg-name ${prefix}-vmNSG \
--priority 100 \
--source-address-prefixes $(curl -s inet-ip.info) \
--destination-port-ranges 22 \
--access Allow \
--protocol Tcp
# SSH 接続します
ssh azureuser@${prefix}.$region.cloudapp.azure.com
Ubuntu Pro に移行
こちらのサイトを参考に Pro に移行します。
