Docker nginx attachment - getting 413

[drissical]

Actual behaviour

Using the docker image I am not able to attach anything over 1M in size. I am able to upload files that are ~950K, I was able to zip a failing 1M file to just under 1M and get it uploaded like that. I checked the size settings per the documentation, and they both look ok.
Logging in to cli via docker exec

bash-5.0# php -i | grep -e "filesize" -e "max_size"
post_max_size => 32M => 32M
upload_max_filesize => 32M => 32M

bash-5.0# grep client nginx/*
nginx/nginx.conf:        client_max_body_size      32m;

(I am not sure how to check the running config of nginx like with php so I am assuming that the setting is either incorrect, ignored, overridden)

Expected behaviour

The PHP settings and Nginx settings look like they are set to 32M already. I would expect to be able to upload an attachment up to 32M.

Steps to reproduce

1. Docker run the latest image
2. Login to the site
3. Create a project
4. Create a task
5. Attach a file over 1M

Logs

Logs actually do not show any errors (i dont think it is generating an error, just a legitimate error code for the user). I stopped and started nginx without the daemon mode settings (nginx -g "daemon off;") so that the logs would go directly to the console and I only seen some PHP constant already defined errors which is fine. They are related to the database and my guess is that these just exist in the docker verison.

Configuration

• Kanboard version: v1.2.18
• Database type and version: 10.4.17-MariaDB-1:10.4.17+maria~stretch
• PHP version: 7.3.25
• OS: Linux 4.19.0-13-amd64
• Browser: (Using the Chromium Edge) Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4412.0 Safari/537.36 Edg/90.0.796.0

I just realized that the php -i might not pull the same settings as it is cli vs nginx/fpm, just incase I created a phpinfo and threw that in the web dir.

I just tested with the Docker image v1.2.18 and I am able to upload files up to the limit of 32MB.

However, I can see on your screenshot that you have Nginx 1.19.3, but the Docker image comes with Nginx 1.18.0 which makes me think that you have a reverse proxy in front of the Kanboard container. This Nginx has probably different settings that the one bundled into the Docker image.

Ah I did not even think about that. Thanks for catching that, going to go down that route now!

Closing this issue for now.
