I have CoreOS beta (1153.4.0)
I'm trying to run calicoctl to check if my calico networking is properly configured. so I'm trying to run a calicoctl rkt container with the command rkt run quay.io/calico/ctl and I get the output
image: using image from local store for image name coreos.com/rkt/stage1-coreos:1.13.0
image: using image from local store for image name quay.io/calico/ctl
networking: loading networks from /etc/rkt/net.d
networking: loading network default with type ptp

trying to execute calico from the command line using rkt run quay.io/calico/ctl --exec calicoctl returns stage1: failed to configure systemd: unable to find "calicoctl" in "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
trying to exec /bin/sh to see what's going on there I get the output
image: using image from local store for image name coreos.com/rkt/stage1-coreos:1.13.0
image: using image from local store for image name quay.io/calico/ctl
networking: loading networks from /etc/rkt/net.d
networking: loading network default with type ptp
and then it quits.
any ideas?
update
with latest version of calico-ctl I get a different error message:
# rkt run quay.io/calico/ctl --exec /calicoctl -- status
image: using image from local store for image name coreos.com/rkt/stage1-coreos:1.14.0

回答1:
Calicoctl is stored in the filesystem root /
The rkt run syntax isn't ideal, but here's how you can run it with additional arguments
sudo rkt run quay.io/calico/ctl --exec /calicoctl -- version
image: using image from local store for image name coreos.com/rkt/stage1-coreos:1.12.0
image: using image from local store for image name quay.io/calico/ctl
