Portainer; Install tutor inside a container

Hello everybody,
I have been trying to spin tutor directly inside a container on a Portainer platform
I encounter some issues like:

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.
    
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    
    See /usr/share/doc/python3.12/README.venv for more information.

I do not want to have a docker-in-docker as tutor is trying to spin up a docker as well.

  1. Has anyone able to setup tutor directly inside a container? Please help.
  2. Should I look into doing openedx (production/devstack) ways?

Any pointer or direction, suggestion will be highly appreciated. Many thanks!
Hear from you soon.

God blesses!!!

Hello Sanyaade,

Please consider creating a python virtual environment inside the tutor directory using the following command:
python3 -m venv venv
after that activate the virtual environment using this command:
source venv/bin/activate
then you should be able to install tutor inside that environment using pip install -e . and completing your tutor installation.

Hi @FuadBader,

Just give a go, but the installation fails again.
Same issue and problem trying to execute a docker-compose (alas in a docker container) file inside a docker container.

The error:

Hoops, screenshot images restriction. This forum wont allow me to upload the error images

I am looking at the repository again to see if I could late the main-installer scripts for study and adaptation

God blesses!!!

Hello @sanyaade-teachings,
Could you please provide more context on what docker image/container you are using to deploy Tutor?

Best regards

Hi @FuadBader

Good day to you, many thanks for your continuous support.
I am try deploy a tutor inside an ubuntu 22.04 container.
I have a portainer ce (https://www.portainer.io/ ) platform running a server. I could create an ubuntu container and ssh into it to deploy tutor. I think the issue as I believe is that tutor installer scripts is configure to spin up its own container whereas in my case, I already have a container running and I am inside it.

If I could locate tutor main installer script then, may be I could override those section to have a non-dockerised tutor installation.

Many thanks for your support. Much appreciated!

Hear from you soon.

God blesses!!!
