bootit

Playground for Java Spring Boot

Run in Kubernetes

Build and push app to a private container registry

You need to add the private registry credentials to Docker

docker login <registry-url> <user> <pass>

Then push the image to it

$ ./gradlew dockerPush  

Fire up the cluster

Follow the setup instructions for bootit cluster. Then hit some endpoints, e.g. http://localhost:8002/api

Next (notes for myself)

Kubernetes

• API versions to stable where possible
• Review/cleanup of yaml files in general
• Check if elk namespace should not be applied with the rest
• monitor postgresql with elk, alert on certain queries
• simplify port mapping: all endpoints for general use to 80
• check out https://github.com/fabric8io/configmapcontroller for redeploying after configmap updates

App

• correlation ID (can it be sent to db queries as well?)
• authorization, oauth2 providers
• check if mq code can be mostly removed (besides listener)
• rest calls to elastic? (RestTemplate)
• javax.validation of params
• faster unit test (less spring init)
  • https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html
• check spring cloud and kubernetes integration
• circuit breaker with hystrix
