Question

我希望能够使用./script.sh -e "${env}" -a "${app}"调用此脚本。 -e（环境），而-a（应用程序）。基本上，通过将环境设置为stage或prod，它会自动获取IP地址。注意：我正在使用Jenkins并从GIT中提取代码。目标不是在脚本中对IP进行硬编码以重用代码。

有什么想法吗？

#!/bin/bash

while [[ $# > 1 ]]
do
OPTIONS="$1"

case $OPTIONS in
    -a|--application)
    APPLICATION="$2"
    shift # past argument
    ;;
    -s|--ip)
    HOSTS_STAGE="$2"
    shift # past argument
    ;;
    -p|--ip)
    HOSTS_PROD="$2"
    shift # past argument
    ;;
    --default)
    DEFAULT=YES
    ;;
    *)
            # unknown option
    ;;
esac
shift # past argument or value
done

echo "########################################"
echo "##  OS Updates on ${APPLICATION}  ##"
echo "########################################"


if [[ "${ENVIRONMENT}" == 'stage' ]]; then
IPS="${HOSTS_STAGE}"

elif [[ "${ENVIRONMENT}" == 'prod' ]]; then
IPS="${HOSTS_PROD}"

fi


echo "---------------------------------------"
echo "##  Performing update in ${ENVIRONMENT}"
echo "---------------------------------------"

for ip in $IPS; do

    echo "---------------------------------------"
    echo "##  Running yum update on ${ip}"
    echo "---------------------------------------"

    ssh -i "${id_rsa}" -o StrictHostKeyChecking=no dvopsadmin@${ip} "df -h"
    done

   if [[ ${REBOOT} == y ]]; then
   for ip in $IPS; do
       echo "---------------------------------------"
       echo "## Rebooting server on ${ip}"
       echo "---------------------------------------"

       ssh -i "${id_rsa}" -o StrictHostKeyChecking=no dvopsadmin@${ip} "uname -a"
       done
   else
      echo "------------------------------------------"
      echo "##  Updates alredy performed withot reboot"
      echo "------------------------------------------"

   fi

我建议您使用EnvInject Plugin。您可以使用此插件在Git项目的顶部设置env变量。请查看链接以获取说明。您可以创建两个env变量，例如APP＆amp; ENV。

然后在“Execute shell”部分中，您可以使用env变量。

./script.sh -e "${ENV}" -a "${APP}"

编辑：

if [ "${ENVIRONMENT}" == 'stage' ]; then 
    IP="${IP_S[@]}" 
elif [ "${ENVIRONMENT}" == 'prod' ]; then 
    IP="${IP_P}" 
fi 

for host in ${IP}; do 

    echo "---------------------------------------" 
    echo "## Running yum update on ${host}" 
    echo "---------------------------------------" 


    if [ "${REBOOT}" == 'y' ]; then 
        ssh -i "${id_rsa}" -o StrictHostKeyChecking=no dvopsadmin@${host} "uname -a; df -h" 
    elif [ "${REBOOT}" == 'n' ]; then 
        ssh -i "${id_rsa}" -o StrictHostKeyChecking=no user@${host} "uname -a" 
    fi 
done
