Feedback Loop implementation in CI/CD pipeline using Jenkins and kubernetes

Currently I am trying to implement CI/CD pipeline using the DevOps automation tools like Jenkins and kubernetes. And I am using these for deploying my micro services creates using spring boot and maven projects.

Now I am successfully deployed my spring boot micro services using Jenkins and Kubernetes. I am deployed to different namespaces using kubernetes. When I am committing , one post commit hook will work from my SVN repository. And that post commit hook will trigger the Jenkins Job.

My Confusion

When I am implementing the CI/CD pipeline , I read about the implementation of feed back loops in pipeline. Here I had felt the confusion that , If I need to use the implementation of Feedback Loops then which are the different ways that I can follow here ?

Can anyone suggest me to find out any useful documentations/tutorials for implementing the feed back loops in CI/CD pipeline please?

Solution

  • The method of getting deployment feedback depends on your service and your choice. For example, you can check if the container is up or check one of the rest URL.

    I use this stage as a final stage to check the service: 

     stage('feedback'){
        sleep(time:10,unit:"SECONDS")
        def get = new URL("192.168.1.1:8080/version").openConnection();
        def getRC = get.getResponseCode();
        println(getRC);
        if(getRC.equals(200)) {
            println(get.getInputStream().getText());
        }
        else{
            error("Service is not started yet.")  
        }
    }

    Jenkins can notify users about failed tests(jobs) with sending email or json notify. read more: https://wiki.jenkins.io/display/JENKINS/Email-ext+plugin

    If you want continuous monitoring for the deployed product, you need monitoring tools which are different from Jenkins.
