I am wondering what version of CentOS is supported for the latest Component Pack. I know it says 7. Something plus on the requirements page but does that mean only versions of 7 or version 7 and above?
The main reason I am asking is because I am trying to install it on version 8 and when running the nfs setup scripts they fail because nfs-lock is not present. It seems to me that CentOS 8 uses a different version of NFS where nfs-lock is not required. I got past this by removing the check for it in the script and everything seems fine apart from ElasticSearch the pods won’t start stating issues with the PVs.
NOTE: Recommended OS for this automation is CentOS/RHEL 7.9. All HCL Connections, Docs and Component Pack builds are done on CentOS/RHEL 7. While it is being tested, in different scenarios, using version 8+ of both CentOS and RHEL you may hit different issues that are eventually not being tested.
It took place of CentOS since they changed their orientation. And we've made very good experiences with it. It is also available on most Cloud Providers (AWS, GCP, Azure).
Well I was actually looking at CentOS Stream which is CentOS8 at the moment but it looks like stick with 7 is what we should be doing and is more than likely why I am seeing issues.
As far as we have tested, current versions of Connections, Docs and Component Pack work without issues on CentOS 8 Stream. Except for Db2, there we had some problems.
Therefore, I would recommend staying on the officially supported versions, at least for Connections and Docs.
Component Pack, however, should work on any x86 Linux, as long as it runs a supported version of Docker and Kubernetes.
DB2 11.1.4.6 is actually fully supported by IBM on RHEL 8 (and so should work fine too on CentOS 8 stream). I have it running on CentOS 8 stream and have encountered no problems. 11.1.4.6 is supported for Connections 7 (officially DB2 11.1.4.5 and future fixpacks).
