For now, we must run the container with UID 0 and privileged for multiple reasons: * the rook binary writes ceph config to /var/lib/rook which is owned by root * it's difficult to use /etc/ceph since it will conflict with the rook-ceph-override configmap AND is also owned by root since it's a mounted configmap. * using /etc/ceph might be possible but has other issues with rook's exec package since the ceph config is built from /var/lib/rook Closes: https://github.com/rook/rook/issues/9385 Signed-off-by: Sébastien Han <seb@redhat.com>
