Kubernetes 1.15部署日记-使用kubeadm--<5-6>

5.配置pod网络

5.1下载calico 网络配置文件

[root@k8s-1 libj]# curl -O https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

% Total % Received % Xferd Average Speed Time Time Time Current

Dload Upload Total Spent Left Speed

100 19533 100 19533 0 0 9207 0 0:00:02 0:00:02 --:--:-- 9204

[root@k8s-1 libj]# ls

calico.yaml kubeadm.yaml

[root@k8s-1 libj]# vim calico.yaml　

5.2直接创建calico网络

[root@k8s-1 libj]# kubectl apply -f calico.yaml

创建完成后查看状态

[root@k8s-1 libj]# kubectl get node

NAME STATUS ROLES AGE VERSION

[root@k8s-1 libj]# kubectl get pods

No resources found.

[root@k8s-1 libj]# kubectl get pods --all-namespaces

6.添加node到集群

6.1在node节点上执行

[root@k8s-2 ~]# kubeadm join 192.168.111.51:6443 --token u5455t.tnp9bx2lkm0wgzhl \

> --discovery-token-ca-cert-hash sha256:7811481be449b5464c80532986be38a670553ce3de102ef375b7cc1fceabcac9

[preflight] Running pre-flight checks

[preflight] Reading configuration from the cluster...

[preflight] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -oyaml'

[kubelet-start] Downloading configuration for the kubelet from the "kubelet-config-1.15" ConfigMap in the kube-system namespace

[kubelet-start] Writing kubelet configuration to file "/var/lib/kubelet/config.yaml"

[kubelet-start] Writing kubelet environment file with flags to file "/var/lib/kubelet/kubeadm-flags.env"

[kubelet-start] Activating the kubelet service

[kubelet-start] Waiting for the kubelet to perform the TLS Bootstrap...

This node has joined the cluster:

* Certificate signing request was sent to apiserver and a response was received.

* The Kubelet was informed of the new secure connection details.

Run 'kubectl get nodes' on the control-plane to see this node join the cluster.

[root@k8s-2 ~]#
