I am getting an error in Lab 16.2 as follows. I did a diff of the file from SOLUTIONS tarball and see it is correct.

student@master:~$ sudo systemctl restart haproxy.service
Job for haproxy.service failed because the control process exited with error code.
See "systemctl status haproxy.service" and "journalctl -xe" for details.

Help!

    Hi @vvandana,

    I would recommend revisiting the haproxy.cfg file (even if diff shows no differences). What typically works in this case is to backup the original haproxy.cfg file on the ha-proxy node, then create a new haproxy.cfg file and copy/paste the content from the file with the same name from SOLUTIONS. Or, just scp it over from the control plane node to the ha-proxy node. Spacing and indentation are causing most issues with this exercise.

    Also, make sure you have updated the first server line of the backend k8sServers section towards the bottom of the file, by replacing "cp1" with your control plane node's hostname followed by your control plane node's private IP address (in a later step the second "cp2" and third "cp3" control plane nodes details will be updated as well).

    Regards,
    -Chris
