cloud-provider: OpenStack
To be able to provision volumes on cloud-provider it is needed to mount and format disk to particular VM and pod. The kubelet is run using hyperkube and it required udevadm tool to perform mentioned task.
Hyperkube itself doesn't have udevadm included so I have to mount it manually, but it leads to some additional shared libs dependencies. So that my current variant for mounting udevadm into hypekube image is following:
...
--volume iscsiadm,kind=host,source=/usr/sbin/iscsiadm \
--mount volume=iscsiadm,target=/usr/sbin/iscsiadm \
--volume udevadm,kind=host,source=/bin/udevadm \
--mount volume=udevadm,target=/usr/sbin/udevadm \
--volume systemd-libs,kind=host,source=/usr/lib/systemd/libsystemd-shared-235.so \
--mount volume=systemd-libs,target=/usr/lib/systemd/libsystemd-shared-235.so \
--volume cryptsetup-libs,kind=host,source=/lib64/libcryptsetup.so.4 \
--mount volume=cryptsetup-libs,target=/usr/lib/x86_64-linux-gnu/libcryptsetup.so.4 \
--volume seccomp-libs,kind=host,source=/lib64/libseccomp.so.2 \
--mount volume=seccomp-libs,target=/usr/lib/x86_64-linux-gnu/libseccomp.so.2 \
--volume devmapper-libs,kind=host,source=/lib64/libdevmapper.so.1.02 \
--mount volume=devmapper-libs,target=/usr/lib/x86_64-linux-gnu/libdevmapper.so.1.02 \
...
Is there any elegant way to add additional bins/apps to the hyperkube instead of mounting a lot of libs?
