I am using Ubuntu bionic (18.04) with latest version of kubeadm on Ubuntu's repositories (1.13.4) and calico 3.6, following their documentation for "Installing with the Kubernetes API datastore—50 nodes or less" (https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/calico).
It was started with:
sudo kubeadm init --pod-network-cidr=192.168.0.0/16But when I apply calico.yaml my node gets stuck with the condition:
Conditions: Type Status LastHeartbeatTime
LastTransitionTime Reason Message ---- ------ ----------------- ------------------ ------ ------- MemoryPressure False Mon, 15 Apr 2019 20:24:43 -0300 Mon, 15 Apr 2019 20:21:20 -0300 KubeletHasSufficientMemory kubelet has sufficient memory available DiskPressure False Mon, 15 Apr 2019 20:24:43 -0300 Mon, 15 Apr 2019 20:21:20 -0300

When I see the system pods (kubectl get pods -n kube-system) I get:

Try removing the taint on the master node, kubectl taint nodes --all node-role.kubernetes.io/master-.
