Snyk Boot Web Demo - Pas DOTC Events

Steps to create the container image

• Ensure you have JDK 11 installed as follows

$ java -version
java version "11.0.13" 2021-10-19 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.13+10-LTS-370)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.13+10-LTS-370, mixed mode)

• Build the artifact image as follows

$ mvn package
[INFO] Scanning for projects...

• Make sure Springboot JAR file was created at "target/snyk-boot-web-0.0.1-SNAPSHOT.jar"

• Create a container image as follows here I am using Dockerhub and you would need Docker desktop running to perform these steps

$ docker build --tag=snyk-boot-web:latest .
$ docker tag snyk-boot-web:latest {userID}/snyk-boot-web:latest
$ docker push {USERID}/snyk-boot-web:latest

Run on Kubernetes

• The following Kubernetes config file exists in the ./kubernetes folder you can use that as a starting guide.

Note: No service is exposed so you can't access the application without a Service or using port forward to allow access. The Kubernetes integration does not need the application exposed

apiVersion: apps/v1
kind: Deployment
metadata:
  name: snyk-boot-web
  namespace: apples
spec:
  selector:
    matchLabels:
      app: snyk-boot-web
  replicas: 1
