Norman, It seems that this repository isn't using our kubelet-wrapper script which ships with the dependencies (like socat) in the rkt fly container the kubelet is run in.
See: https://coreos.com/kubernetes/docs/latest/kubelet-wrapper.html You should be able to modify the cloud-configs to make use of the kubelet-wrapper. I think it should be as easy as just editing the ExecStart of the kubelet.service unit to point to /usr/lib/coreos/kubelet-wrapper: - name: kubelet.service command: start content: | [Unit] After=docker.socket Requires=docker.socket [Service] Environment=KUBELET_VERSION=v1.3.4_coreos.0 ExecStart=/usr/lib/coreos/kubelet-wrapper \ --allow-privileged=true \ --api-servers=http://master.k8s:8080 \ --cloud-provider=aws \ --cluster-dns=10.3.0.10 \ --cluster-domain=cluster.local \ --config=/etc/kubernetes/manifests \ --kubeconfig=/etc/kubernetes/kubeconfig.yml \ --register-node=true \ --tls-cert-file=/etc/kubernetes/ssl/k8s-worker.pem \ --tls-private-key-file=/etc/kubernetes/ssl/k8s-worker-key.pem Restart=always RestartSec=5 [Install] WantedBy=multi-user.target Cheers, Kyle Brown On Tue, Aug 16, 2016 at 11:07 AM, Norman Khine <[email protected]> wrote: > Hello, I have setup a multi-zone coreos cluster using > https://github.com/kz8s/tack all seems to work apart from when i try to > port-forward and i get this error > > ➜ ~ kubectl port-forward trint-mongodb-2-94074312-6uzb3 37017:27017 > Forwarding from 127.0.0.1:37017 -> 27017 > Forwarding from [::1]:37017 -> 27017 > Handling connection for 37017 > E0816 11:08:45.179697 9528 portforward.go:327] an error occurred > forwarding 37017 -> 27017: error forwarding port 27017 to pod > trint-mongodb-2-94074312-6uzb3_default, uid : unable to do port > forwarding: socat not found. > E0816 11:09:44.409445 9528 portforward.go:173] lost connection to pod > ➜ ~ kubectl get pods > NAME READY STATUS RESTARTS AGE > trint-mongodb-1-4062934469-1v7ts 1/1 Running 0 49m > trint-mongodb-2-94074312-6uzb3 1/1 Running 0 1h > trint-mongodb-3-2820699583-cz5lz 1/1 Running 0 1h > > > any advise on how to resolve this? >
