Re: [atomic-devel] looking for feedback on running kubernetes in system containers


Great work Jason!  We should definitely get these images into

I have done something similar for the openshift-ansible.  I got some
changes in that let us use the existing bind mounts:


What I did here is to read the configuration from
/var/lib/etcd/etcd.etcd/etc instead of /etc/etcd when using a system
container since that path is already bind mounted in the container.
With this change in openshift-ansible we don't need any modification in
the etcd image.

in this case we will probably need to modify the image, the existing
bind mounts don't seem enough to do something similar as for etcd.
