preface

1, this article took 4 to 5 days to finish 2, poking fun at yourself feel a bit stupid k8s network access that piece of card time is a bit long k8s under 3, continue to study under the network for this at the application level first chew TouTouDe 4, a responsible attitude Articles within each step are my own practice 5, original is not easy, please mercilessly forward to more people in need to see if I can have such an article for the first time, so it will not be so difficultCopy the code

Build the Nacos environment locally

Download code resources

https://gitee.com/pingfanrenbiji/nacos.git
Copy the code

Compile Nacos

mvn -Prelease-nacos clean install -U -Dmaven.test.skip=true 
Copy the code

Start the Nacos

. / distribution/target/nacos - server - 1.3.0 - BETA/nacos/bin/startup. Sh -m standaloneCopy the code

Download the User and Order code resources

https://gitee.com/pingfanrenbiji/nacos-example.git
Copy the code

Starting the User service


Start the Order service


Viewing registration status

http://127.0.0.1:8848/nacos
Copy the code
nacos/nacos


Verify that user can access order

Access localhost:8100/ k8S to view logsCopy the code

Docker-like order and User services

Generate jar packages for order and user, respectively


The directory structure is as follows



Create separate Dockerfile files



Generate the mirror

Sudo docker build-t user-image:v1.0. Sudo docker build-order :v1.0.Copy the code


Push the image to aliyun Docker library

  • The url
https://cr.console.aliyun.com/cn-hangzhou/new
Copy the code
  • Play tag
Sudo docker tag user - image: v1.0 registry.cn-shanghai.aliyuncs.com/mengfanxiao/user-image:v1.0Copy the code
Sudo docker tag order - image: v1.0 registry.cn-shanghai.aliyuncs.com/mengfanxiao/order-image:v1.0

  • push
sudo docker push registry.cn-shanghai.aliyuncs.com/mengfanxiao/user-image

sudo docker push registry.cn-shanghai.aliyuncs.com/mengfanxiao/order-image

Copy the code


K8s deploys 2 Dockers

  • Create a user. Yaml

  • Create the order. Yaml

  • The deployment of
kubectl apply -f user.yaml
kubectl apply -f order.yaml 
Copy the code

  • View the deployment Pods
kubectl get pods
Copy the code

kubectl get pods -o wide
Copy the code

Enter the cluster environment and check whether the PODS are accessible to each otherCopy the code
kubectl run busybox --rm=true --image=busybox --restart=Never -it


  • Look at the service
kubectl get svc
Copy the code

  • Check the ingress
kubectl get ingress
Copy the code

  • Check to see if the User and Order services were successfully registered with NACOS

IP is the IP address of the Pod

At this point, the user and server springboot projects run as pod and register with the nacOS service on the hostCopy the code

Problem assistance mode

  • Check whether the Pod Docker Imags version number is correct
kubectl describe pods|grep user
Copy the code

  • View pod Docker startup logs
kubectl logs -f order-65d5b4d858-rgnfs
Copy the code
  • Check the port number mapping in k8S service startup files such as order.yaml

To be continued

  • Order is accessed using service NodeType
  • Access user via ingress nginx
  • Test whether user can access order
