概要
ローカル環境に SUSE Rancher Desktop をインストールし、そこに Dify Community版 を構築してみました。その手順となります。
Dify は誰でも簡単にAIアプリケーションを開発できるオープンソースのアプリケーションです。
ローカル環境
- MacBook Pro 16-inch 2019
- プロセッサ：2.3GHz 8コア Intel Corei9
- グラフィックス：Intel UHD Graphics 630 1536MB
- メモリ：32GB 2667MHz DDR4
- macOS Sequoia 15.5
- Rancher Desktop v1.19.3
- docker 28.1.1-rd
- dify 1.5.1
構築手順
1. 以下のコマンドを実行して Dify の構築準備をします
## GitからDifyを取得します
$ git clone https://github.com/langgenius/dify.git

## dify/docker ディレクトリに移動
$ cd dify/docker
2. docker-compose.yaml の中身を確認します
$ cat docker-compose.yaml

冒頭メッセージにあるように環境ファイルを利用して構築します（必要であれば編集）
## 環境ファイルの作成（コピー作成）
$ cp .env.example .env
3. Rancher Desktopを起動します
$ rdctl start
INFO[0000] About to launch /usr/bin/open -a /Applications/Rancher Desktop.app ...
4. dify を構築します。
$ docker compose up -d

Error response from daemon: error while creating mount source path '/Users/ituru/MyDevelops/RancherDesktop/dify/docker/volumes/redis/data': chown /Users/ituru/MyDevelops/RancherDesktop/dify/docker/volumes/redis/data: permission denied
db領域がうまくマウントできない RancherDesktop側の既知の問題 ようです
RancherDesktop画面にてVirtual Machine の Emulation を「VZ」変更し、Virtual Machine の Volumes を「virtiofs」変更します
再度 Dify を構築します

5. Difyのステータスを確認します
$ docker ps -f name=docker --format "table {{.ID}}\t{{.Image}}\t{{.Status}}"
CONTAINER ID IMAGE STATUS

6. dify にアクセスできるか確認します
$ curl http://localhost/install
404 page not found
アクセスできません、、、、、フロントアプリである nginx の起動ポート番号を調べてみます
$ docker port 340915985fea
80/tcp -> 0.0.0.0:80
80/tcp -> [::]:80
443/tcp -> 0.0.0.0:443
443/tcp -> [::]:443
80番ポートを利用している別アプリを調べてみます
## 80番ポートの利用チェック
$ lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 18182 ituru 22u IPv4 0xfcf39e2c6f2004ed 0t0 TCP *:http (LISTEN)
## 上記で取得したPIDでプロセスをgrep
$ ps -axwwo user,pid,ppid,pgid,command | grep 18182
ituru 18182 1 18182 ssh: /Users/ituru/Library/Application Support/rancher-desktop/lima/0/ssh.sock [mux]
どうやら80番ポートは RancheDesktop で利用しているようです。デフォルトでTraefikがEnableになっているためです
7. 環境設定ファイルの変更（.env ファイルの編集）
以下のように nginx の利用ポート番号を変更します
# ------------------------------
# Docker Compose Service Expose Host Port Configurations
# ------------------------------
# EXPOSE_NGINX_PORT=80
# EXPOSE_NGINX_SSL_PORT=443
EXPOSE_NGINX_PORT=8888
EXPOSE_NGINX_SSL_PORT=8443
8. 再度 Dify を構築します

## nginx ポート確認
$ docker port 840c1a699d6f
80/tcp -> 0.0.0.0:8888
80/tcp -> [::]:8888
443/tcp -> 0.0.0.0:8443
443/tcp -> [::]:8443
9. 再度 dify にアクセスできるか確認します
$ curl http://localhost:8888/install
コマンドラインでうまくいったようなので、ブラウザで実際にアクセスしてみます。
その時に起動しているコンテナ一覧を RancherDesktop で確認してみました。
10. 後処理
Rancher Desktopを停止します
## Dify の停止
$ docker compose down
[+] Running 12/12

## RancherDesktop の停止
$ rdctl shutdown
Shutting down.
11. おまけ
オープンソースソフトウェアである Dify のアップデート内容を過去にクローンしたDifyに反映させる方法
$ cd dify/docker
$ git pull origin main
$ docker compose down
$ docker compose pull
$ docker compose up -d
まとめ
Rancher Desktop 上で Difyを起動するところまで確認できました。次は実際にDifyを動かしてみようかと思います。
