I've created a kubenetes cluster on my Mac with docker-machine, following the documentation here:
http://kubernetes.io/docs/getting-started-guides/docker/
I can access the normal api from inside the instance on 127.0.0.1:8080, but I want to access it externally from my macbook. I know there is a secure port :6443, but I'm unsure how to set up the credentials to access this port.
There are lots of instructions on how to do it on custom installs of kubernetes, but I don't know how to do it inside the docker containers I'm running.
It's like a workaround but most of the time, I think KubeOnDocker setup is for developper that don't need the credentials mecanism :
When you start the KubeOnDocker, --config=/etc/kubernetes/manifests point to master.json. If you look the apiserver start command, you will see that --insecure-bind-address is 127.0.0.1. If you use --config=/etc/kubernetes/manifests-multi it will point to master-multi.json, --insecure-bind-address will be 0.0.0.0 and the apiserver will be accessible from everywhere.
Note that you will need to start etcd with manifests-multi.
# Not tested start
docker run \
-d \
--net=host \
gcr.io/google_containers/etcd:2.2.1 \
/usr/local/bin/etcd \
--listen-client-urls=http://127.0.0.1:4001 \
--advertise-client-urls=http://127.0.0.1:4001 \
--data-dir=/var/etcd/dataLikely, you will want to use Virtual Box's port forwarding capabilities. An example from the documentation:
VBoxManage modifyvm "MyVM" --natpf1 "k8srule,tcp,,6443,,6443"This forwards port 6443 on all hosts interfaces to port 6443 of the guest. Port forwarding can also be configured through the VirtualBox UI.
