kubelet can't start without "shared" volume on Travis

[reachlin]

this is about more investigation on this issue

without the "shared" flag on this line, the calico can't start properly. the "shared" works fine on local box, but not on travis.

In your docker service unit file you have to set shared MountFlags

[Service]
Type=notify
ExecStart=/usr/bin/docker daemon -H fd://
MountFlags=shared
LimitNOFILE=1048576

IIRC, --volume=/var/lib/kubelet:/var/lib/kubelet:rw,rslave also works. You can have a try.

@dixudx ok, running travis now: https://travis-ci.org/reachlin/k8s0/builds/273147090

[dixudx]

well, no luck.

Try add drop-in for docker unitfile.

@dixudx how? this is on Travis...

[reachlin]

so this is still sth. Travis has to fix for their docker image?

@reachlin You're running kubelet through hyperkube. Please append --containerized after "hyperkube:v1.6.4", "kubelet"
