仮想化の検討
今後の可用性も考えて、サーバーに載せているサービスの仮想化やコンテナ化を考えてみる。
対象はなんだろう
- samba
- gogs
- nextcloud
- mydns/グローバルIP監視
- ログインログアウト監視（Slack連携)
- MariaDB
- webmin
gogs
まずはgogs

データの引っ越し
- データベース

- config
データベース
mysqldump -u git -p gogs_git > gogs.sql.bak
mysql -u gogs -p gogs --port=13306 < /home/adeno/gogs.sql.bak
gogs-repositories
data/gogs/data/gogs-repositoriesにコピー

ROOT = /app/gogs/data/gogs-repositories
結局
gogs backup

初期設定でのデーターベース設定は以下を参考にした。

なにか方法があるのか
- rootless
- rootless + SELinux
- Podman
https://e-penguiner.com/rootless-docker-for-nonroot/
https://matsuand.github.io/docs.docker.jp.onthefly/engine/security/rootless/
https://matsuand.github.io/docs.docker.jp.onthefly/engine/security/userns-remap/
https://docs.docker.jp/desktop/install/linux-install.html#linux-install-file-sharing
docker rootlessを試してみる
いろいろ試行錯誤したのを一旦整理
まずは普通のインストール
https://docs.docker.com/engine/install/ubuntu/
以下の手順のみLinux Mintでは異なるので注意
3.Use the following command to set up the repository:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
$ lsb_release -cs
vanessa
UbuntuのOSバージョンを表示させるにはUBUNTU_CODENAMEが必要
$ cat /etc/os-release
NAME="Linux Mint"
VERSION="21 (Vanessa)"
ID=linuxmint
ID_LIKE="ubuntu debian"
PRETTY_NAME="Linux Mint 21"
VERSION_ID="21"
HOME_URL="https://www.linuxmint.com/"
SUPPORT_URL="https://forums.linuxmint.com/"
BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/"
PRIVACY_POLICY_URL="https://www.linuxmint.com/"
VERSION_CODENAME=vanessa
UBUNTU_CODENAME=jammy
なので
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
としちゃう。
動作確認
これで、普通モードの動作確認ができる
sudo docker run hello-world
rootlessモード

良いね。状態取れた。
サンプルを実行してみる
$ docker run hello-world
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
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/

こちらも同様

.bashrcに書いた
export XDG_RUNTIME_DIR=/home/gogs_docker/.docker/run
が余計だったのかな・・・。
これをコメントアウトして試してみる
これで
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/docker.sock
docker-compose ps

今度こそ大丈夫そう。
改めてデータの引っ越しをする。
データの引っ越し
- データベース
- gogs-repositories
- config
データベース
mysqldump -u git -p gogs_git > gogs.sql.bak
mysql -u gogs -p gogs --port=13306 < /home/adeno/gogs.sql.bak
gogs-repositories
data/gogs/data/gogs-repositoriesにコピー
データの所有者を100999（コンテナ内のgit(10000)相当）にしておく
config
[repository]
ROOT = /app/gogs/data/gogs-repositories
ホスト名をgogs_mariadb_1にする
これでOKOK
更新ができない
なぜか、もともとの/home/git/gogs-repositoriesを参照しようとする。
困ったので、最終手段でシンボリックリンクを張った。
