Docker Compose Build Failure: Externally Managed Environment Error

Description

When attempting to build Caldera using Docker Compose, the build process fails due to an "externally-managed-environment" error during the Python package installation step.

Environment

• Caldera version: 4.1.0
• Docker Compose file version: Not specified (marked as obsolete)
• Base image: ubuntu:latest
• Python version: 3.11.8 (on host system)

Steps to Reproduce

1. Clone the Caldera repository (ensuring recursive clone for plugins)
2. Navigate to the Caldera directory
3. Run docker-compose build

Error Message

ERROR [caldera  8/26] RUN pip3 install --no-cache-dir -r requirements.txt
------
 > [caldera  8/26] RUN pip3 install --no-cache-dir -r requirements.txt:
0.512 error: externally-managed-environment

0.512 × This environment is externally managed
0.512 ╰─> To install Python packages system-wide, try apt install
0.512     python3-xyz, where xyz is the package you are trying to
0.512     install.

... (error message continues)

0.512 hint: See PEP 668 for the detailed specification.
------
failed to solve: process "/bin/bash -c pip3 install --no-cache-dir -r requirements.txt" did not complete successfully: exit code: 1

Expected Behavior

The Docker Compose build should complete successfully, installing all required Python packages.

Actual Behavior

The build fails at the step where pip is trying to install the Python packages listed in requirements.txt.

Possible Cause

This error appears to be related to PEP 668, which introduces the concept of externally managed environments. The Ubuntu image used in the Dockerfile might be enforcing this policy, preventing pip from installing packages globally.

Suggested Solutions

1. Modify the Dockerfile to create and use a virtual environment for package installation.
2. Use a different base image that doesn't enforce this restriction.
3. Update the Dockerfile to use apt for installing Python packages instead of pip, where possible.
4. If appropriate, consider adding the --break-system-packages flag to the pip install command (use with caution as it may lead to system instability).

Additional Information

• The error occurs after successfully installing python3, python3-pip, git, curl, and mingw-w64.
• The Docker build process seems to be using 31 steps, with the error occurring at step 8.

Any assistance in resolving this issue would be greatly appreciated. Thank you!

By trying suggested changes (--break-system-packages) it still did not work and broke later in building c packages.

I was wondering if there is pre-built docker images just like TRAM so i can just do docker-compose up and it works.
