Can I use kubectl from my host?

[scholzj]

You should be able to simply copy the kubeconfig file to your local PC and use kubectl from there. There are two versions of kubeconfig - one for use through DNS name of your cluster and one for use through IP address (in case you don't want to wait for DNS propagation or don't have a public DNS zone).

Weird because when I type kubectl cluster-info dump --kubeconfig=kubeconfig_ip using either kubeconfig or kubeconfig_ip I got a Unable to connect to the server: dial tcp 52.208.98.119:6443: i/o timeout.

Is your minikube setup in public network (i.e. network with route to AWS Internet Gateway)? Can you ping the IP address?

So the E2C is in public network because if I allow ICMP in my-minikube security group I can ping it. Ports 6443 and 22 are already allowed too. Here is my config.tfvars :

I just run terraform apply -var-file=config.tfvars

[scholzj]

The config file looks OK. I'm a bit surprised if you got your minikube running on t2.micro. But if it works from the machine it self than it should be fine.

I would expect that the problem must be somewhere in the Amazon configuration which blocks the access. But it is hard to guess what might be the problem without knowing the AWS setup you are using for subnets. I also assume that you can SSH / SCP into the host fine form the same computer, right? Could you try to run the 'kubectl' command with '--v=9' option? Maybe it would produce some more output.

One thing which comes to my mind - do you have some HTTP proxy configured? I saw some problem like this when proxy was in use.

I finally resolved my problem by just using a google cloud cluster. Anyway thanks a lot for your help and for your great project!
