USER_INSTALL_DIR=/ibm/jupyter
Save the file as responsefile.properties in folder /ibm/install
Change the rights on the file, so dockeruser can access it
chown dockeruser:docker responsefile.properties
Run the unattended install:
Make dockeruser able to run docker commands
chmod 666 /var/run/docker.sock
Change to dockeruser
sudo su dockeruser
Go to the /ibm/install folder
cd /íbm/install
Enter this command
./ca_instl_lnxi38664_2.0.191205.bin -DREPO=/ibm/install/ca_jupyter_lnxi38664_11.1.5.zip -f responsefile.properties -i silent
Check the log file for errors – in folder /ibm/jupyter/uninstall/logs
Install jupyter:
Go to folder /ibm/jupyter/dist/scripts/unix
Enter ./install.sh to run the installation
When finish, test the notebook, from IE browse to it at http://linuxservername:8000
If above show, then you are a success, go then to Cognos Analytics.
If you get a error during install like;
Error step 3/12 : Copy –chown=ca_user:users pip.conf $HOME/.config/pip/ .
Unknown flag: chown
Above error is solved by replace the file “Dockerfile_server_instance” with this content:
# IBM Cognos Products: Notebook
FROM ca_jupyter_server_instance_original:installed
USER ca_user
WORKDIR $HOME
# copy additional_packages & install if not empty
# COPY –chown=ca_user:users pip.conf $HOME/.config/pip/.
# COPY –chown=ca_user:users additional_packages.txt .
# Change below
COPY additional_packages.txt .
USER root
RUN chown ca_user:users additional_packages.txt
USER ca_user
WORKDIR $HOME
COPY pip.conf $HOME/.config/pip/.
USER root
RUN chown -R ca_user:users $HOME
USER ca_user
WORKDIR $HOME
# Stop change
RUN if [ -s additional_packages.txt ]; then \
pip install –user -r additional_packages.txt; \
fi \
&& rm additional_packages.txt
# install certificates for trusted external servers as root
USER root
WORKDIR /tmp
COPY build-tmp certificates
RUN if [ `ls -1 /tmp/certificates/*.crt 2>/dev/null | wc -l` -ne 0 ]; then \
cp /tmp/certificates/*.crt /usr/local/share/ca-certificates/; \
chmod 754 /usr/local/share/ca-certificates/*.crt; \
update-ca-certificates; \
fi \
&& rm -rf certificates
# switch to notebook user
USER ca_user
WORKDIR $HOME
Save the file as Dockerfile_server_instance2
Copy the file over to /ibm/install/ folder on the linux server
Rename the Dockerfile_server_instance to Dockerfile_server_instance_org
Rename the Dockerfile_server_instance2 to Dockerfile_server_instance
Change access to the file
chmod 755 Dockerfile_server_instance
Run the install again from the unix folder
./install.sh
https://pypi.org/project/pixiedust/#files
If you get a error like Could not fetch URL https://pypi.org/simple/pixiedust/: There was a problem confirming the ssl certificate HTTPSConnectionPool (host=’pypi.org’, port=443): Max retries exceeded with url: /simple/pixiedust….
Then the Linux box have not access to internet, and can not download the software. Solve by temporary allow the Linux box Internet access during installation.
You can also try to do this steps:
Open IE on your laptop and paste this line, to download the tar file.
https://files.pythonhosted.org/packages/16/ba/7488f06b48238205562f9d63aaae2303c060c5dfd63b1ddd3bd9d4656eb1/pixiedust-1.1.18.tar.gz
Copy the pixiedust-1.1.18.tar.gz file over to /ibm/install folder on linux server with WINSCP program.
Change the user access
chown dockeruser:dockeruser pixiedust-1.1.18.tar.gz
Extract the file with command
tar -xvf pixiedust-1.1.18.tar.gz
Change the owner of all files in folder with command
chown dockeruser:docker pixiedust-1.1.18
Go to folder /ibm//jupyter/dist/scripts
Edit the file additional_packages.txt
nano additional_packages.txt
Comment out all the lines and then add the following line:
–no-index –find-links=/ibm/install/pixiedust-1.1.18 pixiedust
Save the file and exit nano program
Go to the folder unix and run the install again;
cd /ibm/jupyter/dist/scripts/unix
./install.sh

- If you want to integrate Cognos Analytics for Jupyter Notebook Server, you must add a rule to map WebSocket requests from IBM Cognos Analytics notebooks to the back end Jupyter Notebook Server.
For more information, see Installing IBM Cognos Analytics for Jupyter Notebook Server.
Important You must also install WebSocket Protocol support in IIS. For more information, see WebSocket <webSocket> (https://docs.microsoft.com/en-us/iis/configuration/system.webserver/web socket).
- Select the ibmcognos alias. Click on URL rewrite icon.
- Click Add Rules > Inbound Rules > Blank Rule .
- If proxies are not already enabled, you are prompted to enable. Click OK.
- The server name and port are defined in the config.conf file when you configure Jupyter Notebook Server.
-
- Select the newly created rule and click Edit.
- Pattern is v1/jupyter/(user/[^/]*)/(api/kernels/[^/]+/channels)
- Action type is Rewrite.
- Rewrite URL (for SSL configurations) is https://jupyter_host_name:jupyter_host_port/bi/v1/jupyter/{R:1}/{R:2}
Note For non-SSL configurations use the following rewrite URL: http://jupyter_host_name:jupyter_host_port/bi/v1/jupyter/{R:1}/{R:2}
-
- Check Append query string.
- Check Stop processing of subsequent rules.
- Click Apply and Back to Rules.
If above step is missed you get above error.
