  • 1.  Installation of ICPD boot helm chart fails

    Posted Mon June 03, 2019 08:45 AM
    Hi all,

    my ICPD installation now fails right after ICP install. When trying to install the 0005-boot helm chart in step ['InstallBaseModule'], at the end of the log I receive this error:

            "stdout_lines": [

    Some lines earlier the log shows quite many stderr_lines like this:

    There's a 
    "WARNING! Using --password via the CLI is insecure..." 
    which _should_ be no problem as it's a warning, no error.

    Here're the bottom lines from stdout_lines:

    Has anybody seen this error before or an idea how to fix this?

    Hi Bernd,

    Can you please print the below command output of any pod in zen namespace which is in pending or init state .

    kubectl get pod <podname> -n zen -o yaml.

    Thanks,
    Shankar.

    Hi Bernd,

    can you please print the output of the below k8s command of any pod in zen name space which is in state other than running.

    kubectl get pod <podname> -n zen -o yaml.

    Thanks,
    Shankar.

    Hello Shankar,

    thank you for asking. The command you supplied showed no output, because as it seems the related pods haven't been started.

    Anyway, meanwhile I know what went wrong. The pods for the 0005 helm chart reserved a lot of cpu resources which exceeded the provisioned cpu resources that I could provide on my test hardware. So while physically enough cpu was available, some pods didn't start because they couldn't reserve cpu, and others failed because they were depending on the missing ones.

    Solution: After shutting down some other VMs and assigning 8 cpu to each ICP4D node (as documented by IBM), the error was gone.

    What I learned:
    - installing ICP _should_ get away with 4 cpu on each node (and upgrading later), while
    - installing ICP4D does need at least 8 cpu on each node from the beginning.

    ------------------------------
    Kind regards
