Hello everyone,

I’m trying to start a Tutor instance in a Proxmox container. I have installed the latest versions of Docker and Docker Compose. However, when the application is building, I keep encountering the same issue. The error below still appears, even after creating a new container with better resources.
I’ve already tried modifying the docker-compose.yml file, but every time I run “tutor local launch”, the changes I made are reverted.

Can anyone help me with this?

Container specs:
8GB RAM;
20GB HDD;

root@teste-tutor-v3:~# tutor local launch

Hi, Lucas, Biz-teixeira
docker-compose.yml is updated every time you try to start.
One question, did you build the images?

tutor images build openedx
tutor images build mfe

Hello Juan,

I just tried running “tutor local launch” after using “pip install ‘tutor[full]’”, as the tutorial instructs. Could you explain what these commands do?

Thanks!

What happened to you is to build the images in docker, maybe you are missing making a
tutor dev launch

5

Understood, but I don’t need to develop the platform; I just want to run the testing environment of Tutor to host some courses, not to work in development mode. Do you have any other recommendations for this?

This thread looks like about your case. I’m not familiar with Proxmox, but

container-based with LXC

from Wikipedia about Proxmox gives a clue: Error setting rlimits type 8 (operation not permitted: unknown) in LXD container - LXD - Linux Containers Forum

Hello,
First : Don’t load from the root account, but use your user account
Then :

  • Did you install from pip or from binary?
  • try “systemctl edit docker” to edit the docker configuration
