🚀 Deploying Spring Boot Microservices using Cyclops ☸️⚓

Hello folks,

Let me quickly introduce you guys about Cyclops before we start.

What is Cyclops?

Cyclops is a web-based tool designed to simplify the containerization process of apps in Kubernetes. Cyclops gives as an intuitive web form where we can configure our app seamlessly and also it provides us a dashboard where we can view all our pods, deployments, services. Moreover, it provides us key metrics like cluster's performance, resource utilization and health. It helps us to onboard quickly without spending much time on configuring things.

GitHub Link: .

minikube start

kubectl apply -f https://raw.githubusercontent.com/cyclops-ui/cyclops/v0.8.2/install/cyclops-install.yaml

kubectl apply -f https://raw.githubusercontent.com/cyclops-ui/cyclops/v0.8.2/install/demo-templates.yaml

kubectl port-forward svc/cyclops-ui 3000:3000 -n cyclops

Creating Microservices and Deploying to Cyclops

1. I have created a student service which communicates with library service using rest template



2. 
   

   Dockerfile of student service is as below
   
   

   
   
   CODE Kopieren

   FROM openjdk:17-jdk-alpine
   
   WORKDIR /studentService
   
   COPY target/studentService-0.0.1-SNAPSHOT.jar studentService.jar
   
   EXPOSE 8090
   
   ENTRYPOINT ["java", "-jar", "studentService.jar"]
   
   

   
   
   


3. 
   

   Dockerfile of library service is as below
   
   

   
   
   CODE Kopieren

   FROM openjdk:17-jdk-alpine
   
   WORKDIR /libraryService
   
   COPY target/libraryService-0.0.1-SNAPSHOT.jar libraryService.jar
   
   EXPOSE 8090
   
   ENTRYPOINT ["java", "-jar", "libraryService.jar"]
   
   

   
   
   


4. 
   

   Now we will build the images of both the services by checking out to each service folder where Dockerfile is present:
   
   

   
   
   CODE Kopieren

   docker build -t student-service .
   
   docker build -t library-service .
   
   

   
   
   


5. 
   

   Let's tag this images and push to docker hub!
   
   

   
   
   CODE Kopieren

   docker tag student-service your-dockerhub-username/student-service:latest
   
   docker tag library-service your-dockerhub-username/library-service:latest
   
   docker push your-dockerhub-username/student-service:latest
   
   docker push your-dockerhub-username/library-service:latest
   
   

   
   
   



6. To deploy this services we generally define Deployment and Service YAML files. But here Cyclops comes into play and does that for us. We just need to create modules and wait for it to be up and running!



7. 
   

   Now that we deployed microservices to Cyclops, we should also be able to access them from our browser and to do that forward the ports!
   
   

   
   
   CODE Kopieren

   kubectl port-forward svc/student-service 8090:80
   
   kubectl port-forward svc/library-service 8090:80
   
   

   
   
   

How I Contributed to Cyclops

Cyclops team has opened

After creating a modules, the module card shows repo and path link. Now, this when path link was clicked it used to take use to broken Github link by eating current page.

Solution:

I have made changes such that when path link is clicked it opens in a new tab. And also, broken path link was fixed by using resolvedVersion _in url if present, if not then by using _version _ else using _main.
