Spring Multipart upload with docker --read-only

Question

Hello I am trying to run my container with --read-only, but when I receive a request for multipart upload i tries to create a temporary file:

java.nio.file.FileSystemException: /tmp/undertow3773194840223053389upload: Read-only file system.

Is it possible to make it only in memory?

thanks =)

Answer 1

You can use something like below

docker run -it --read-only --tmpfs /tmp alpine sh

This will allow you to write files in /tmp. So what you need is a additional --tmpfs /tmp in your docker run command
