应用程序可以在AWS Elastic Beanstalk中创建文件吗？

Question

Our web application is deployed to Elastic Beanstalk instance and from the code, I want to create a text/csv file.

do I need to have permission to create a file? or is it enabled by default?

How should I give permission to create a new file?

Answer 1

Its enabled by default.

In my Java application (running on EBS Tomcat) I use this system property to identify a temporary directory to write to:

// Get a temporary folder to write the attachment file in
final String dirPath = System.getProperty("java.io.tmpdir");

If I remember correctly this just gives me the path /tmp
