    Description

      When discussing best practices and guidelines here: https://docs.couchbase.com/operator/current/best-practices.html#ulimits

          Note that that OCP docs link is considered "subscriber exclusive content", so general walking around folks won't be able to read it.

          Maria Shodunke could you please help push these changes to https://docs.couchbase.com/operator/2.3-beta/best-practices.html#ulimits

           

          Here are the changes - 

          1. right below the first paragraph, add this caution
            [CAUTION]
              ====
              Red Hat OpenShift 4.0 and above sets the default limit of the maximum number of process IDs in the cgroup to be 1024; you can read about this here https://access.redhat.com/solutions/5366631 (Red Hat subscription required). A workaround is to increase the pids_limit in both the KubeletConfig and ContainerRuntimeConfig.
              ====

           

          see this commit for reference - https://github.com/couchbase/couchbase-operator/pull/29/commits/689a40ed9273a5172528e9b7ea169aae9ccd8ff8

          Hi Anil Kumar , I don't seem to have access to this repo?

          I know on Github we have: https://github.com/couchbase/couchbase-operator
          From what I understand any changes need to be submitted in Gerrit?

          I can't find the couchbase-operator repo on Gerrit though...
