準備
リポジトリのセットアップ
aptのパッケージの更新・必要パッケージのインストール
sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
Docker の公式 GPG 鍵を追加
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
リポジトリの登録
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Docker Engine のインストール
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
Docker Composeのインストール

sudo chmod +x /usr/local/bin/docker-compose
確認
sudo docker run hello-world
問題なければ，下記のような結果が出力される

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

上までだと，毎回sudoが必要なので，下記を行うことがおすすめ。
