【问题描述】:
我正在使用 Node.js,需要将文件保存到我的应用程序中的 tmp 目录。问题是 Elastic Beanstalk 没有将应用程序目录设置为可由应用程序写入。所以当我尝试创建临时目录时,我得到了这个错误
fs.js:653
return binding.mkdir(pathModule._makeLong(path),
^
Error: EACCES, permission denied '/var/app/tmp/'
at Object.fs.mkdirSync (fs.js:653:18)

我已经尝试了几件事,例如 .ebextensions/scripts/app-setup.sh 中的 app-setup.sh 脚本,看起来像这样
#!/bin/bash
# Check if this is the very first time that this script is running
if ([ ! -f /root/.not-a-new-instance.txt ]) then
newEC2Instance=true
fi
# Get the directory of 'this' script
dirCurScript=$(dirname "${BASH_SOURCE[0]}")
# Fix the line endings of all files
find $dirCurScript/../../ -type f | xargs dos2unix -q -k
# Get the app configuration environment variables
source $dirCurScript/../../copy-to-slash/root/.elastic-beanstalk-app
export ELASTICBEANSTALK_APP_DIR="/$ELASTICBEANSTALK_APP_NAME"
appName="$ELASTICBEANSTALK_APP_NAME"
dirApp="$ELASTICBEANSTALK_APP_DIR"
dirAppExt="$ELASTICBEANSTALK_APP_DIR/.ebextensions"
dirAppTmp="$ELASTICBEANSTALK_APP_DIR/tmp"
dirAppData="$dirAppExt/data"
dirAppScript="$dirAppExt/scripts"
# Create tmp directory
mkdir -p $dirApp/tmp
# Set permissions
chmod 777 $dirApp
chmod 777 $dirApp/tmp
# Ensuring all the required environment settings after all the above setup
if ([ -f ~/.bash_profile ]) then
source ~/.bash_profile
fi
# If new instance, now it is not new anymore
if ([ $newEC2Instance ]) then
echo -n "" > /root/.not-a-new-instance.txt
fi
# Print the finish time of this script
echo $(date)
# Always successful exit so that beanstalk does not stop creating the environment
exit 0
除了在 .ebextensions 中创建一个名为 02_env.config 的文件,看起来像这样
# .ebextensions/99datadog.config
container_commands:
01mkdir:
command: "mkdir /var/app/tmp"
02chmod:
command: "chmod 777 /var/app/tmp"
似乎都不起作用。如何在我的应用程序中创建可写的 tmp 目录?
【问题讨论】:
-
只是好奇,为什么要在无状态系统中写入文件?
