[rajeshnawale]

When I change the base image ubuntu to OEL 8.x and when I try to buid the image and container getting below error. Container is not coming up.

Traceback (most recent call last):
File "/scripts/start.py", line 41, in
from opengrok_tools.config_merge import merge_config_files
ModuleNotFoundError: No module named 'opengrok_tools'

Evidently the startup script cannot find the Python package. Looking at the Dockerfile, the package is installed into a Python virtual environment

opengrok/Dockerfile

Line 91 in bd5f18a

RUN /venv/bin/python3 -m pip install --no-cache-dir /opengrok/tools/opengrok-tools.tar.gz && \

under /venv so it would probably help if the startup script used /venv/bin/python3. It is suprising to me that it actually works in Debian (which is the basis of the eclipse-temurin:21-jdk image used by the tomcat:10.1.50-jdk21 image).

Replacing the curent version's

opengrok/Dockerfile

Line 126 in bd5f18a

CMD ["/scripts/entrypoint.sh", "/scripts/start.py"]

with CMD ["/scripts/entrypoint.sh", "/venv/bin/python3", "/scripts/start.py"] might do the trick.

It is suprising to me that it actually works in Debian (which is the basis of the eclipse-temurin:21-jdk image used by the tomcat:10.1.50-jdk21 image).

It works because the /venv/bin is in the prefix of the PATH environment variable

opengrok/Dockerfile

Line 90 in bd5f18a

ENV PATH=/venv/bin:$PATH

and script.py uses env to find python3.
