{{name}}

Running in local development environment

mvn spring-boot:run

Packaging and Running in docker environment

mvn package -B -DskipTests
docker build -t username/{{name}}:v1 .
docker run username/{{name}}:v1

Push images and running in Kubernetes

docker login 
# in case of docker hub, enter your username and password

docker push username/{{name}}:v1

Edit the deployment.yaml under the /kubernetes directory:

    spec:
      containers:
        - name: {{name}}
          image: username/{{name}}:latest   # change this image name
          ports:
            - containerPort: 8080

Apply the yaml to the Kubernetes:

kubectl apply -f kubernetes/deployment.yaml

See the pod status:

kubectl get pods -l app={{name}}

If you have no problem, you can connect to the service by opening a proxy between your local and the kubernetes by using this command:

# new terminal
kubectl port-forward deploy/{{name}} 8080:8080

# another terminal
http localhost:8080

If you have any problem on running the pod, you can find the reason by hitting this:

kubectl logs -l app={{name}}

Following problems may be occurred:

  1. ImgPullBackOff: Kubernetes failed to pull the image with the image name you've specified at the deployment.yaml. Please check your image name and ensure you have pushed the image properly.
  2. CrashLoopBackOff: The spring application is not running properly. If you didn't provide the kafka installation on the kubernetes, the application may crash. Please install kafka firstly:
