Zabbix serverをdocker-composeで立ち上げる
dockerをインストール
適宜
イメージをダウンロード
zabbix/zabbix-docker: Official Zabbix Dockerfiles https://github.com/zabbix/zabbix-docker/blob/6.4/docker-compose_v3_alpine_mysql_latest.yaml を選択。
Tips
※ secretsを利用しているようだが設定が正しくされないのでenv_filesを利用した。
設定の書き換え
Zabbix Docker Installation | Mike Polinowski を参考に、agentのIPアドレスを確認して管理画面よりIPアドレスを書き換える。
Tips
サービスの指定 下記のようにサービスを選択しないと、zabbix-agent、zabbix-snmptrapsが自動起動しなかった。
$ docker-compose up -d zabbix-server zabbix-web-nginx-mysql zabbix-agent mysql-server db_data_mysql
Linkが自動作成されない

IPアドレスを書き換えてもActiveにならない。下記で明示的にエイリアスを指定する必要がある
