Docker Installation on Single Node

[michallawson]

When I try and install the component pack (single node) I receive an error in TASK [docker-install : Add {{__kubectl_user}} to the group docker] The task includes an option with an undefined variable. The error was : {{kubectl_user | default (ansible_env['SUDO_USER']) dict object has no attribute 'SUDO_USER'

Will be grateful for you advice on what is wrong.

Many thanks

Hey Michael, what OS you are running it on, and what version?

Normally, (ansible_env['SUDO_USER']) means that whatever user is running Ansible is registered inside the machine in Ansible environment as SUDO_USER.

Also, you can add to the bottom of your inventory file this line:

kubectl_user="michallawson"

...and in case your user that you are running Ansible with is that one, it will set up everything needed for that user. Can you try that?

Thank you for your help.

Following the earlier problems, I gave up on Centos 8 and reverted to Centos 7. Everything is now running for the installation of DB2, TD, WAS & Connections but think I may have made a mistake by setting the remote_user variable to root as WAS will now only run as the root user.

Will tweak the remote_user setting to a SUDO user and run the installation of connections and the component pack to see if this resolves the problem.

Kind regards

Michael

Regarding CentOS 8 - we are looking into that topic currently, but that is a part of a bigger discussion regarding the builds as well, not only setting up third part software. My feeling currently is - from what I saw with both RHEL and CentOS - is to stick with v7 and run yum update. At least for the moment being.

I do not envy you and I will be sticking to Centos 7 for some time.

Changed the remote_user variable to SysAdmin and installation seems to have completed and just need to test everything.
