mastodon を立てたはいいけど全然アップデートしていなかったのでアップデートする。

こんな感じのダメ管理者が行った備忘録です。
TL;DR
- 所要時間
- コーヒー3杯、タバコ5本
- サービスダウン時間
- 停止、DBのマイグレーション、プリコンパイル、起動まで。うちの環境で50分くらい※
- 対象
- docker版のmastodonである
- 参考にさせてもらいました
- Docker を利用したマストドンのアップデートメモ
※プリコンパイルを起動後にやって再起動する手順にすればもっと短縮できる気がする。
$ cd path/to/mastodon
$ git fetch
$ git stash
$ git tag
$ git checkout [バージョン番号]
$ git stash pop
$ sudo docker-compose pull
$ sudo docker-compose build
$ sudo docker-compose down
$ sudo docker-compose run --rm web rails db:migrate
$ sudo docker-compose run --rm web rails assets:precompile
$ sudo docker-compose up -d
やること
現在、ver 1.6.1 でした。最新版の 2.3.2 に上げます。
壊す前のバックアップ
よく壊しちゃうので、最悪何とかなるようバックアップしておきます。といっても、外側からざっくりとるバックアップです。気休めかもしれません。
mastodon インスタンスを探す
うちの mastodon は EC2 上にいるはずなので、そいつを探します。いました。
ボリュームのスナップショットをとる
ふむ。1つしかボリュームないので、そいつをクリックしてボリューム管理画面からスナップショットを作成します。
名前つけとかは適当に。
スナップショット管理画面で進捗を確認します。うちのは最大30GBみたいなので、すぐ終わるでしょう。コーヒー淹れてきます。
ステータスが緑のcompletedになれば完了です。
ちなみに、この方法で取得したバックアップを実際に使ったことないのでどこまで使えるのかはわかりませんよ。
どういう構成だったのか調べる
普通の人は、こんなこと必要ないと思います。でも、私って現場合わせの仕事が多いんで、普段からそういうのできるようにしておこうっていう勉強がてらあ・え・て、メモとか書かないんです。書いても読まないんです。その辺の話は追々書きたいな。
何が動いているかチェック
私流でいくと、ディストリビューションが何であるかとか、バージョンいくつであるとか、そういうの後回しです。とにかく、「ps -ef」です。

確認ポイント
- PID 1 一番上のプロセスが何か
- []がついてるのはひとまず無視
- TIMEが多めのやつ
- 知らない名前のやつがいないか
PID 1 のやつを見るのは、数年前までは init しかほぼなかったので気にする必要なかったんですけど、最近だと systemd が出てきたのでそれによって確認するポイントやコマンドが変わってくるので、その判断のためです。
TIMEが多めのやつってのは、要はたくさん動いてるやつなので何者かチェックしとく。
知らないやつは危険なのでちゃんとググる。
なるほど。と。ここまでで、dockerでmastodonが動いていて nginx, telegraf が個別に動いてるんやな。他はまぁいいか。ってことがわかりますね。
プロセスマネージャ？の情報見る
正式名称しらないけど、PID 1 のやつのことです。systemd なのでとりあえず、systemctl status とでも打っておきます。

degradedですね。ぷ。。まぁ、予想通りの結果ですね。
dockerがどうなってるか確認
docker ps あたりで。あ、ちなみにわたし、dockerのこと詳しくないです。なので雰囲気でやってます。
[centos@don ~]$ sudo docker ps

まぁ、mastodon関係のやつしかいないし、mastodon の docker-compose.yml を探して変更箇所確認しておけば平気かな。
docker-compose.yml を確認
[centos@don mastodon]$ cat docker-compose.yml

postgresqlとredisをローカルにマップして永続化してるくらいしか変更点なさそうですね。
確認結果まとめ
- docker版のmastodonである
- nginxとtelegraf動いているけどそこは無視しよう
で、やりかたググります。
Docker を利用したマストドンのアップデートメモ
これで良さそうですね。いいねボタン押しておきます→Qiitaアカウント持ってなくて押せませんでしたゴメンなさい。
アップデート
手順通りに進めて行くだけですね。

[root@don mastodon]# git checkout v2.3.2
Note: checking out 'v2.3.2'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b new_branch_name
HEAD is now at 6cc432b... Bump version to 2.3.2
なんか言ってますねぇ。英語？わかりませんよ。でも、雰囲気的にこれは問題ないヤツってことで無視しておきます。

なんか増えてるなぁ。でも、永続化のところはちゃんと反映されてるので問題ないでしょう。

ぐはっ。これはいかんですね。dbに接続できないみたい。
could not translate host name “db” to address: Name does not resolve
ですか。ん～、すでに起動してるからかなぁ。とりあえずググりますか。
トラブルシューティング
・Dockerでdocker-composerを使用し、PG::ConnectionBad: could not translate host name “db” to address: Name does not resolveが出る場合、docker-composeコマンドを走らせる前に、docker-compose down（Volumesを使用し、データを失わないようにしてください！）を実行する必要があるかもしれません。
ですよね！

本当に動いているのか心配になりますねぇ。Duplicate Session しても反応返ってこないですねぇ。頑張っているんでしょう。
嫌だけど気になるので Enter 押してみました。30秒くらいしてから改行されましたね。大丈夫、動いてます。コーヒー淹れましょう。
やっと終わった。45分くらいかかりましたねぇ。
