systemdが有効なcentos 7コンテナでイカサービスを開始できません。
イカパッケージをインストールできます。
サービスを開始する前に取得した内容は次のとおりです。
[root@c65bf5111b85 /]# systemctl status squid
● squid.service - Squid caching proxy
Loaded: loaded (/usr/lib/systemd/system/squid.service; disabled; vendor preset: disabled)
Active: inactive (dead)
その後、systemctl start squidを実行すると、次のような結果が表示されます。
[root@c65bf5111b85 /]# systemctl status squid
● squid.service - Squid caching proxy
Loaded: loaded (/usr/lib/systemd/system/squid.service; disabled; vendor preset: disabled)
