Getting Started
Before diving into the code, ensure you have a good understanding of Java and Spring concepts. A basic understanding of Spring Boot REST services will also be beneficial. An eagerness to learn and explore microservices is key!
How to Execute Maven Commands
Maven is your best friend. Let’s understand it with a little analogy. Imagine you’re organizing a grand event. The Maven commands are like your event checklist—they help you ensure everything is set before the big day. Here are the top Maven commands you’ll frequently use:
mvn clean install -Dmaven.test.skip=true // Generate a jar inside target folder
mvn spring-boot:run // Start a Spring Boot Maven project
mvn spring-boot:build-image // Generate a Docker image using Buildpacks
mvn compile jib:dockerBuild // Generate a Docker image using Google Jib
Docker Commands Explained
Docker is akin to a well-organized container system in which each piece of your application lives in its own box, ready for shipping. Here’s how to use Docker commands:
docker build . -t eazybytesaccounts:s4 // Generate a Docker image
docker run -p 8080:8080 eazybytesaccounts:s4 // Start a Docker container
docker images // List all Docker images
docker ps // Show running containers
Kubernetes Commands Unraveled
Kubernetes can be visualized as a manager issuing commands to maintain harmony in your application environment. Here are some essential commands:
kubectl apply -f filename // Create a resource based on YAML
kubectl get all // Get all cluster components
kubectl delete pod pod-id // Delete a specific pod
Troubleshooting Tips
During your learning process, you may run into hurdles. Here are some troubleshooting tips:
- Command Fails: If your Maven or Docker commands fail, double-check the syntax and ensure all dependencies are installed.
- Service Not Running: Use the command
docker ps -ato check the status of your containers. - Kubernetes Pod Issues: Run
kubectl describe pod pod-idfor detailed insights into pod failures. - Networking Problems: Ensure your ports are correctly configured to avoid connection issues.
