Sorry for last post. After further testing, I found it's not working. Here is more details:
Environment (AWS VPC ec2 x 2 medium) OS: ubuntu 16.04 LTS
[preflight] running pre-flight checks [WARNING RequiredIPVSKernelModulesAvailable]: the IPVS proxier will not be used, because the following required kernel modules are not loaded: [ip_vs ip_vs_rr ip_vs_wrr ip_vs_sh] or no builtin kernel ipvs support: map[nf_conntrack_ipv4:{} ip_vs:{} ip_vs_rr:{} ip_vs_wrr:{} ip_vs_sh:{}] you can solve this problem with following methods: 1. Run 'modprobe -- ' to load missing kernel modules; 2. Provide the missing builtin kernel ipvs support [discovery] Trying to connect to API Server "172.31.57.36:6443" [discovery] Created cluster-info discovery client, requesting info from "https://172.31.57.36:6443" [discovery] Requesting info from "https://172.31.57.36:6443" again to validate TLS against the pinned public key [discovery] Cluster info signature and contents are valid and TLS certificate validates against pinned roots, will use API Server "172.31.57.36:6443" [discovery] Successfully established connection with API Server "172.31.57.36:6443" [kubelet] Downloading configuration for the kubelet from the "kubelet-config-1.12" ConfigMap in the kube-system namespace configmaps "kubelet-config-1.12" is forbidden: User "system:bootstrap:tlx9nt" cannot get resource "configmaps" in API group "" in the namespace "kube-system"
Try on master
kubectl get node NAME STATUS ROLES AGE VERSION ip-172-31-57-36 Ready master 57m v1.12.1
Master shows join failed.
