在 Rancher 升级时,当存在环境变量时,未执行替换的分析解决

1、当存在环境变量时,未执行替换,文件 /etc/nginx/conf.d/pcs.conf 中的变量未被替换,/config/init/change.log 中存在替换记录,如图1

2、查看容器日志,报错:sed: couldn’t open file ww/pcs/build/config.js: No such file or directory

3、PCS_CFG_CALLBACK_LOGIN=https://cmclogin.chinamcloud.com/login/index?call_back=http://wjdev2.chinamcloud.com:8657/#/topic/add ,其值中存在 #,因此为了防止冲突,需要将 # 替换为 @。且 sed -i” 替换为 sed -i “,缺少空格。

    env | grep "PCS_CFG_CALLBACK_LOGIN" || export PCS_CFG_CALLBACK_LOGIN="PCS_CFG_CALLBACK_LOGIN"
        sed -i "s@PCS_CFG_CALLBACK_LOGIN@$PCS_CFG_CALLBACK_LOGIN@g" $BUILD_CONFIG_PATH
        echo "PCS_CFG_CALLBACK_LOGIN replace $PCS_CFG_CALLBACK_LOGIN -> $BUILD_CONFIG_PATH"
        echo "PCS_CFG_CALLBACK_LOGIN replace $PCS_CFG_CALLBACK_LOGIN -> $BUILD_CONFIG_PATH" >> $DIR/change.log

4、文件 /etc/nginx/conf.d/pcs.conf 中的变量已被成功替换,如图2
