Push the modified code according to the self environment to the remote:
git add .
git commit -m "description"
git push origin master # (git push origin local branch name: refs/remotes / remote branch name) just push the code to the remote
Build on jenkins:
Create a new task (spring cloud Eureka) -- build a maven project -- OK

Install the cloud docker plug-in in jenkins:

Continue to configure springcloud Eureka: configure the image construction of docker

Then jenkins builds it

rancher deploys eureka services and deploys workloads
spring-eureka
192.168.109.137:5000/spring-eureka
Port 8000 TCP HostPort 8000
Host scheduling deploy=worker because eureka needs to register with each other, so the previous label is not used here. We change it to iprange=138
Advanced options: whether the host network is selected for the network (yes). The -- net=host command will be added at startup in the background, indicating that the virtual network is not available
After eureka on 138 is started, we need to modify the configuration file in 139 code and repackage it;
My arrangement here is: 142 corresponds to application-142 YML (hostname:192.168.109.139) is deployed on 138 machines
vim /root/111/gitee_cangku/rancher_springcloud/spring-base/spring-eureka/src/main/resources/application.yml comment active: 141, enable active: 142
Submission Code:
git add .
git commit -m "modify configuration deployment 138"
git push origin master
jenkins repackages, 139 because the old version of the local package has been deployed, restarting will not affect, but will only change the image package of the warehouse
rancher clones a spring Eureka service and modifies it:
spring-eureka-138
Host scheduling: iprange = 138
Delete the image on 138 machine: docker RMI 192.168.109.137:5000 / spring Eureka: latest
Then start
Check:
1. Log view
2. When rancher visits the eureka registration page, he can see that DS Replicas is the mutual address, and both stations have been registered successfully, as follows:
SPRING-EUREKA n/a (2) (2) UP (2) - 192.168.109.138:spring-eureka:8000 , 192.168.109.139:spring-eureka:8000
The eureka cluster is now complete
