Originally, I always wanted to be lazy and use kubernetes's kubeadmin deployment tool to automate deployment. However, due to the problem of the software installation source, I was not familiar with the interrelationship of the relevant modules. In addition, because I did not use it in the work and did not have enough enthusiasm, this experiment had not been completed. Later, I subscribed to a Subscription account to introduce kubernetes, or honestly followed the master to install through the binary package. This will also give you a better understanding of the entire architecture of k8s. Refer to this website:

Or use pve virtualization environment to create a test virtual machine, 2-core CPU, 4G memory, and 32G hard disk dome 2 Nic:

The following is the verification content:

Check the cluster status on the master node: # kubectl get nodeNAME STATUS ROLES AGE VERSION192.168.1.42 Ready 30s v1.12.5192.168.1.43 Ready 13s v1.12.December kubectl get csNAME STATUS MESSAGE ERRORcontroller-manager Healthy ok scheduler Healthy ok etcd- 0 Healthy {"health": "true"} etcd-2 Healthy {"health": "true"} etcd-1 Healthy {"health": "true"} run a test example

Create a Nginx Web to test whether the cluster is working properly:

# kubectl run nginx-image=nginx-replicas=3# kubectl expose deployment nginx-port=88-target-port=80-type=NodePort

View Pod,Service:

# kubectl get podsNAME READY STATUS RESTARTS AGEnginx-dbddb74b8-dlkfl 1 to 1 Running 0 44snginx-dbddb74b8-m558r 1 to 1 Running 0 44snginx-dbddb74b8-pwdc9 1 to 1 Running 0 44s# kubectl get svcNAME TYPE CLUSTER-IP EXTERNAL-IP PORT (S) AGEkubernetes ClusterIP 10.0.0.1 443 / TCP 90mnginx NodePort 10.0.0.208 88:48882/TCP 26s

Access the Nginx deployed in the cluster and open the browser and enter: http://192.168.1.42:48882/ http://192.168.1.43:48882/, which can be opened in both node, 192.168.1.42 and 192.168.1.43. As follows:
