Spring Boot very large uploads
docker-compose up
The initial build takes some minutes depending on the Internet connection.
Wait until the terminal stops scrolling.
Open a web-browser on http://127.0.0.1
There’s a simple form to upload a file.
Any uploaded files will be listed on the web-page, underneath the form.
The files are saved on the folder upload_folder in the root directory. This folder is mapped into the spring_run container as a volume on docker-compose.
For the purpose of testing a large file upload, my suggestion is to replace the actual upload_folder using a separate partition or external drive as the upload_folder by the means of a symbolic link.
As such:
ln -s /dev/sdb/some_folder ./upload_folder
Then, on the terminal, you can run a watch df -h during the large file upload and watch the used disk space staled while the destination partition will increase.
Another way to upload files is using a cURL command on the endpoint http://127.0.0.1/upload, as such:
curl -X POST -F file=@/home/dgomes/Downloads/WHDLOAD.7z http://127.0.0.1/upload
