Lesson 8 labs: Can't run tests inside dinamically provisioned agent

mtuli0

Seems like the labs are out of date, I get this error when trying to run the tests for the RSVP app in the container Jenkins agents

+ virtualenv rsvpapp --system-site-packages -v

Hi @mtuli0,

Thank you for your feedback. The lab exercise and repository will be corrected as needed in a future course update release.

@mtuli0 I encountered the same problem. After some debugging it turns out that the pip should be upgraded and after that the virtualenv should be installed.

Update the shell script as:

pip install --upgrade pip #additional line
pip install virtualenv #additional line
virtualenv rsvpapp --system-site-packages -v
source rsvpapp/bin/activate
pip install -r requirements.txt
pytest tests/test_rsvpapp.py
>

Alternatively this could be done in the Dockerfile at 8.1 at section:

>
RUN apt-get install -y python-pip
RUN pip install --upgrade pip #additional line
RUN pip install virtualenv
>

In this case the two additional lines in the shell script won't be needed.

Hi @mtuli0
I encountered the same problem and after some debugging found that pip must be updated before installing virtualenv

This can be done in two different ways:
In the shell script:
pip install --upgrade pip ## additional line
pip install virtualenv ## additional line
virtualenv rsvpapp --system-site-packages -v
source rsvpapp/bin/activate
pip install -r requirements.txt
pytest tests/test_rsvpapp.py

In the Dockerfile in the 8.1 section:
'#Install python related package
RUN apt-get install -y python-pip
RUN pip install --upgrade pip ## additional line
RUN pip install virtualenv

Thank you for your input @GeorgiYadkov. The additional steps will be included in a future course update release to reflect the updated installation process.
