centreon-poller rpm package relies on perl-dbd-mysql

[hecko]

Feature explanation

Remove hard dependency on perl-dbd-mysql rpm package from RHEL8 for centreon-poller rpm

What is the value of the wanted feature ?

RH officially supported UBI8 Docker layer does not offer this package in the list of supported packages
https://hub.docker.com/r/redhat/ubi8

Additional information

perl DBD::MySQL module can be installed using cpanm, but the dependency in centreon-poller does not detect the module being installed.

Dockerfile snippet:

RUN dnf install -y \
    perl-App-cpanminus \
    && dnf clean all
RUN cpanm -v DBD::mysql

Output from Docker image build:

Step 35/84 : RUN dnf install -y     centreon-poller     && dnf clean all

Im closing this. The UBI8 distro has multiple issues running centreon, not just this limitation. Ill re-open the issue if reasonable.
