RUN source command not found

[Fernandez]

Hi all,

I need to use the command source but I get that the following error:

RUN source /etc/project/bin/activate

source: not found

ENTRYPOINT python /etc/project/src/start.py

However, if I enter in the container and run it everything works fine.

What can I do ?

Thanks,

Best,
Fernandez

Hi,

``source`` is not a command. It's a Bash (or shell) function.

Normally it's run inside a Bash shell.

e.g:

source /path/to/bash_script

I'm not entirely sure you can affect the "shell environment"

of the Docker buidl in this way. Not sure...

cheers

This is correct, I recommend creating a script that runs as the entry point.

#!/bin/sh

source /my/project/bin/activate

/my/project/bin/execute

If your using source to read a file that contains environment variables, you could also use ENV in your Dockerfile to set them ..

Just a thought..

Hi Fernandez,

(Switching that thread to docker-user since it's probably more appropriate there...)

In that specific case (running a Python program using virtualenv), the easiest solution is to reference the full path to the Python interpreter in the virtualenv.

In other words:

ENTRYPOINT /etc/project/bin/python /etc/project/src/start.py

HTH,

Thanks Frederic,

I finally decided to define an ENTRYPOINT passing as command the instructions with the absolute path of my virtualenv.

RUN chmod -R 750 /etc/project
ENTRYPOINT /etc/project/bin/activate && /etc/project/bin/python /etc/project/src/start.py

However, I also tried your version but I got a permission denied error. I didn't dig into it but I imagine that adding "RUN chmod ..." prior my script will make it to work.
