cp4d role should check that the correct version of foundational service is installed.

[mattlrx]

issue: When installing a version other than the latest version of MAS, we need to add the version of the supported dependency, for instance, installing MAS 8.7, oneclick_core installs the latest version of cp4d (cloudpak for data) and cpfs (cloudpak foundationnal service) unless you specify the environment variable COMMON_SERVICES_CHANNEL

therefore, the ask would be:

• The cp4d role should check that the correct version of cpfs is installed.
• The common_services role should set a default value for COMMON_SERVICES_CHANNEL based on the CPD_PRODUCT_VERSION, if defined.

Hello @mattlrx , thank you for your feedback.

Can you please inform what's the current problem you are experiencing? That will help us assess the impact of it so we can prioritize accordingly.

I think what you are proposing is a valid enhancement. We want to avoid adding extra logic to automatically manage versions cross different dependencies to make them compatible with each other, because it might become pretty hard for us to maintain our code for the future if we go down that path, however I believe there's a way to check and assert if we're installing a CPD version that is compatible with the current installed version of IBM Common Services / Foundation Services, (this information is already available as part of a configmap that we use to install CPD) and that might be enough to ensure we're keeping both Common Services, as a prereq, and CPD versions aligned and compatible.

Running tests for this issue... this is the preview message users will receive if running incompatible Foundation/Common Services version vs CPD expected one:

TASK [ibm.mas_devops.cp4d : Assert that ibm-common-services is installed and is compatible with CPD version 4.6.4] *****************************************
fatal: [localhost]: FAILED! => {
    "assertion": "foundation_services_installed_csv_version is version_compare(foundation_services_csv_version, '>=')",

    "msg": "Failed! You have incompatible IBM Foundation Services version v3.23.0 installed. You must have version 3.23.1 or above."

This was fixed with the PR above, closing it for now.
