harbor安装小坑

安装harbor需要将hostname修改为本机ip，然后我也修改了（我是先复制了当前hostname那行并注释掉，然后再修改的，如下），但是执行./install.sh安装时候一直报错

#hostname = reg.mydomain.com
hostname = 192.168.174.136

然后看install.sh 脚本，发现脚本是grep原脚本进行校验的，如下：

# The hostname in harbor.cfg has not been modified
if grep 'hostname = reg.mydomain.com' &> /dev/null harbor.cfg
then
        echo "my test"
        warn "$usage"
        exit 1
fi

➜ Please set hostname and other necessary attributes in harbor.cfg first. DO NOT use localhost or 127.0.0.1 for hostname, because Harbor needs to be accessed by external clients.
Please set --with-notary if needs enable Notary in Harbor, and set ui_url_protocol/ssl_cert/ssl_cert_key in harbor.cfg bacause notary must run under https.
Please set --with-clair if needs enable Clair in Harbor
