セットアップの流れ
本家サイトにもスタートアップガイドはありますが、記載は必要最低限になっており、初めての方だと迷われるかもしれません。
そこで、初めての方でも迷わないよう、以下のステップに沿ってVPS WebARENA (Indigo) の簡単なセットアップ手順を紹介したいと思います。
以下の手順を確認する際は、サインアップだけでも実施しておくことをおすすめします。
サインアップだけなら料金は発生しないのでご安心ください。
実際の画面を見ながらの方が、断然理解が進むと思います。
dockerインストール
https://www.linuxtechi.com/install-docker-and-docker-compose-rocky-linux/
リポジトリの追加
docker をインストールするためにリポジトリを追加します。
「dnf」は、Red Hat系のLinuxディストリビューションで使われている“RPMパッケージ”を扱うためのパッケージ管理コマンドです。ソフトウェアのインストール（install）や更新（update）、アンインストール（remove）の際に利用します。
CentOS 7が採用している「yum」の後継となるコマンドという位置付けで、yumと同じサブコマンド、オプションを使用可能です。
$ sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
最新化（アップデート）の実行
リポジトリを追加したらアップデートを実行します。
※３０分くらいはかかりました。
sudo dnf update
実際にアップデートを実行するまえに、アップデートによって必要となるディスク容量が表示されるので、yse(y)を入力します。
