I have pike 5.0.1 release of kolla and I just ran the command kolla-build -b centos -t source It successfully built all container images except for ovsdpdk and kafka images.

So I tried to rebuild them by running

 kolla-build -b centos -t source ovsdpdk

And also ran

kolla-build -b centos -t source kafka

But I always get these errors below

ERROR:kolla.image.build.ovsdpdk:The command '/bin/sh -c echo 'source not yet available for centos'     && /bin/false' returned a non-zero code: 1

ERROR:kolla.image.build.kafka:The command '/bin/sh -c echo 'source not yet available for centos'     && /bin/false' returned a non-zero code: 1

I also tried running the command as kolla-build ovsdpdk kafka and got pretty much the same errors

ERROR:kolla.image.build.ovsdpdk:The command '/bin/sh -c echo 'binary not yet available for centos'     && /bin/false' returned a non-zero code: 1

ERROR:kolla.image.build.kafka:The command '/bin/sh -c echo 'binary not yet available for centos'     && /bin/false' returned a non-zero code: 1

Are these images essential for deploying openstack with kolla-ansible?? Do I really need them? How can I fix these errors?
