Installing a pip package in an offline Linux environment

Install Jupyter Notebook Server, including the additional pip package, without internet access.

About this task

When installing Jupyter Notebook Server, you need to install the PixieDust package additional_pip_packages.txt. This task requires internet access, which in some cases might not be available. So you need to download the package before installing Jupyter.

Procedure

Locate the tar.gz file for your specific package online, and download it.

The Python Package Index (PyPI) pypi.org (https://pypi.org) website can be used to download most pip packages from the source.
Navigate to the /opt/ibm/cognos/jupyter/dist/scripts/ directory, and create a new directory named tmp.
Place all of the tar.gz packages that you downloaded into the tmp directory.
Open the file /opt/ibm/cognos/jupyter/dist/scripts/Dockerfile_server_instance for editing.

Modify the file in the following way:

Under the line:
```
COPY additional_pip_packages.txt /home/ca_user
```
Add the following new line:
```
COPY tmp/ /tmp/
```
This line instructs Docker to take your packages and place them into the Docker container during the build.

Comment out the following section:

#‌COPY additional_conda_packages.txt .
#‌RUN if [ -s additional_conda_packages.txt ]; then \
#‌ conda install --yes --file additional_conda_packages.txt; \
#‌ fi \
#‌&& rm additional_conda_packages.txt

Save the Dockerfile_server_instance file ensuring that it's saved without a file extension.
Open the file /opt/ibm/cognos/jupyter/dist/scripts/additional_pip_packages.txt for editing.
Modify the file in the following way:
1. Remove the line pixiedust==1.1.17
2. Add the following new line /tmp/<package-name>.tar.gz. Ensure that the path matches the exact name of your tar.gz file.
3. Add a new line for every package that you want to install this way.
Save the additional_pip_packages.txt file.
Run the Linux installation script by using the following command: /opt/ibm/cognos/jupyter/dist/scripts/unix/install.sh.
