启动coreos上的calicoctl容器

Question

我有CoreOS测试版(1153.4.0)

我正在尝试运行calicoctl来检查我的calico网络是否配置正确。因此，我尝试使用命令rkt run quay.io/calico/ctl运行calicoctl rkt容器，并得到输出

尝试使用rkt run quay.io/calico/ctl --exec calicoctl从命令行执行calico将返回stage1: failed to configure systemd: unable to find "calicoctl" in "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

尝试执行/bin/sh以查看那里发生了什么，我得到了输出

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

然后它就退出了。

有什么想法吗？

更新

使用最新版本的calico-ctl时，我收到不同的错误消息：

# rkt run quay.io/calico/ctl --exec /calicoctl -- status

Calicoctl存储在文件系统根/中

rkt run语法并不理想，但下面介绍如何使用其他参数运行它

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 networking: loading networks from /etc/rkt/net.d networking: loading network default with type ptp [360361.039942] ctl[5]: 0.22.0-dev
