The complete documentation is as follows:
In
Master, and then use the following command to create the deployment and service Kubectl create-f Kube-tomcat.yaml
View the created Deployment:kubectl get deployment
See the details of this deployment: Kubectl describe deployment Kube-tomcat
View the created Service:kubectl get service
View the details of this service. Kubectl describe service Kube-tomcat service details the IP here is Cluster-ip. Cluster-ip is bound to the service. Service details the port here is the service's port number. Service details The Nodeport here is the true port number of node. Service details the endpoints here is the IP and port of the container.
View the created Pod:kubectl get pod
See the details of one of the pods. Pod details here The IP is the virtual IP in the nodes. The virtual IP can go to nodes inside using Ifconfig view. Kubectl describe pod Kube-tomcat-1115055280-tk1f8
In
nodesTo view the created container:
Then use the browser to access: http://47.97.90.38:8080/api/v1/proxy/namespaces/default/services/kube-tomcat/ Be sure to specify namespaces and services here.
and then to
nodes, the war using "Docker CP" copy to the container's Tomcat/webapps, you can achieve the page access to "here may need to wait more time, at least a few minutes" test in postman note that the IP in the request should be the IP of master. Return success. You can use postman to perform interface testing by indicating successful deployment.
The above steps can also be deployed in conjunction with continuous integration CI/CD, simplifying a number of processes.
