#Deployment

Following the configuration of the application.yml file, the application can be deployed and executed either within a Docker container environment or orchestrated via a Helm chart for Kubernetes (k8s) deployments.

#Docker container deployment

To instantiate the application as a Docker container, execute the following command:

docker run -d \
-p 8080:8080 \
-e SPRING_CONFIG_ADDITIONAL_LOCATION=file:/app/config/ \
-v /path/to/your/config/application.yml:/app/config/application.yml \
--name cs-proxy \
<registry-address>/cs-proxy:<tag>

#Kubernetes deployment (Helm Chart)

For Kubernetes environments, the application can be deployed using the provided Helm chart, accessible at https://{REGISTRY_URL}/repository/helm/.

Installation order:

1. Create a namespace.

   kubectl create namespace codescoring

2. Create a secret to access the private Docker registry, using the address (REGISTRY_URL), login (USERNAME) and password (PASSWORD) received from the vendor.

   kubectl create secret docker-registry codescoring-regcred --docker-server=REGISTRY_URL --docker-username=USERNAME --docker-password=PASSWORD -n cs-proxy

3. Install Helm using your preferred method.

4. Run the following commands to add the current Helm repository to the local machine:

   helm repo add codescoring-org https://{REGISTRY_URL}/repository/helm/ --username USERNAME --password PASSWORD
   helm repo update

5. Create a values.yaml file with the following content:

   env:
     javaOpts: "-Xmx4g" # Optional: JVM parameters configuration
   
   config: |
     # This field must be populated with the content of the application.yml file
   
   # There's an option to create an Ingress resource
   ingress:
     enabled: true
     className: ""
     annotations: {}
     hosts:
       - host: cs-proxy.example.com
         paths:
           - path: /
             pathType: Prefix
             backend:
               service:
                 name: cs-proxy
                 port:
                   number: 8080
     tls:
       - secretName: cs-proxy-tls
         hosts:
           - cs-proxy.example.com

6. Run the command to install the chart

   helm install cs-proxy codescoring-org/cs-proxy -n cs-proxy -f values.yaml --create-namespace --atomic --version CHART_VERSION
