docker composerを利用してWebヘルプデスクツールである「Zammand」を構築するまでの手順を記述してます。

1. 環境
2. docker-compos.ymlダウンロード
3. Zammand起動

環境

OS CentOS Linux release 7.9.2009 (Core)
docker 20.10.2
docker-compose 1.25.4

docker-compos.ymlダウンロード

github上に存在するのでダウンロードします。

git clone https://github.com/zammad/zammad-docker-compose.git

移動します。

cd zammad-docker-compose

ファイルの中は以下のようになってます。
