Cannot create cluster in a network isolated environment #25

Open f-higashi opened 8 years ago

f-higashi commented 8 years ago

Hyperkube v1.2 try to connect internet during creating cluster.

https://github.com/kubernetes/kubernetes/blob/release-1.2/cluster/images/hyperkube/setup-files.sh#L44 https://github.com/kubernetes/kubernetes/blob/release-1.2/cluster/saltbase/salt/generate-cert/make-ca-cert.sh#L78-L82

After v1.3.0-alpha, it is avoided. https://github.com/kubernetes/kubernetes/blob/v1.3.0-alpha.3/cluster/images/hyperkube/Dockerfile#L54

So, when we use this script in an isolated environment, we have to use newer hyperkube image or modified image.

We can evaluate this new hypercube image. We have e2e tests. If they pass in the same result as 1.2 I don't see any problem to use newer hypercube.

@f-higashi good work.

@zreigz, @f-higashi what is the status in kube-deploy project? We should check and create issue or PR there too. Maybe we get some additional information

Today I am going to review it again and test it. I would like create cluster using kube-deploy project and also run e2e tests. I almost finished Vagrant project for it. It helps for testing and future developments.
