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

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.

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).

1. Select the ibmcognos alias. Click on URL rewrite icon.
2. 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.

1. • 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}

1. • Check Append query string.
   • Check Stop processing of subsequent rules.
   • Click Apply and Back to Rules.

• exit iis manager.

If above step is missed you get above error.
