Kubernetes - apiserver advertise address

On vagrant I built a kubernetes cluster with ansible and noticed that the kubeadm init was not using the private interface created on vagrant. So to avoid that, ti changed the command with the parameter --apiserver-advertise-address to use the private ip of the master. 

- name: Start the cluster

  shell: kubeadm init --apiserver-advertise-address={{ inventory_hostname }} --pod-network-cidr 10.50.0.0/16 --cri-socket /run/containerd/containerd.sock

  register: kubeadm_init_output

  when: not file_exists.stat.exists
