如何创建"tmp"目录与Elastic Beanstalk? [英] How can I create a "tmp" directory with Elastic Beanstalk?
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目录中.问题在于,Elastic Beanstalk不会将应用程序目录设置为可写.因此,当我尝试创建临时目录时,会出现此错误
I'm using Node.js and need to save files to a tmp directory within my app. The problem is that Elastic Beanstalk does not set the app directory to be writable by the app. So when I try to create the temp directory I get this error
fs.js:653
return binding.mkdir(pathModule._makeLong(path),
^
Error: EACCES, permission denied '/var/app/tmp/'

我已经尝试了多种方法,例如.ebextensions/scripts/app-setup.sh中的app-setup.sh脚本
I've tried several things such as an app-setup.sh script within .ebextensions/scripts/app-setup.sh that looks like this
#!/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
在.ebextensions中创建一个名为02_env.config的文件,如下所示:
As well as creating a file called 02_env.config within .ebextensions that looks like this
# .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?
Neither seem to work. How can I create a tmp directory within my app that is writable?
推荐答案
我最近在.NET应用程序中遇到了同样的问题,该应用程序失败了,因为即使我设置了权限也无法将其写入目录
I recently experienced the same issue with a .NET application where the application was failing because it couldn't write to a directory, even after I had set the permissions.
我发现,完成整个.ebextensions流程后,最后一步是Web容器权限更新,最终覆盖了我的ebextensions权限更改.
What I found was that after the whole .ebextensions process was completed, the final step was a web container permissions update which ended up overwriting my ebextensions permissions change.
为解决此问题,我将目录移到了Web容器之外,并更新了应用程序以写入该目录.
To solve it I moved the directory outside of the web container and updated the application to write there instead.
在您的情况下,我建议/tmp
In your case I would suggest /tmp
