Raspberry Pi 4B 用のUbuntu Server 18.04.2 64bit のイメージが公開されていたので試してみました。
Docker 環境も構築されています。

UPDATE: 2019/7/14 軽量なイメージが公開されました。

環境構築

準備

  • Raspberry Pi 4B
  • SDカード 32GB
  • https://cloudkernels.net/rpi4-64-bit-kvm-docker.img.xz
  • etcher で書き込み(2.5GB が8.07GB に展開される)
  • 初回ブートに時間がかかる or reboot しないといけないかも
  • root のパスワードは無し
  • pi, ubuntu アカウントが存在する
  • port 80 nginx

    設定(オプション)

  • /etc/hosts にpi4 を追加
    /etc/hosts
    127.0.0.1 localhost pi4
  • sshd のポリシー設定変更
    /etc/ssh/sshd_config
  • ユーザの追加
    $ sudo adduser hoge
    $ sudo gpasswd -a hoge docker
    $ sudo systemctl daemon-reload
    $ sudo systemctl restart docker
  • nginx 無効化
    $ sudo systemctl stop nginx
    $ sudo systemctl disable nginx
