Setting authentication for Docker

Go to your ~/.m2/settings.xml and add the server with id docker-repo

<server>
  <id>docker-repo</id>
  <username>username</username>
  <password>password</password>
  <configuration>
    <email>[email protected]</email>
  </configuration>
</server>

Pushing docker image

Important

Remember to set authentication in your settings.xml

$  ./mvnw package docker:build -DpushImage

or

$  ./mvnw deploy

Running the application in Kubernetes

• First create and push the docker image

  $ ./mvnw package docker:build -DpushImage

• Start minikube

  $ minikube start

• Start Kubernetes Dashboard

  $ minikube dashboard

• Create this deployment on the cluster using kubectl

  $ kubectl create -f deployment.yml

• Check if deployment is there

  kubectl describe deployment github-webhook-deployment

• Create a service to expose the pod to the outside world

  $ kubectl create -f service.yml

• Check if service has properly been created

  $ kubectl describe service github-webhook-service

• Retrieve the URL from minikube

  $ minikube service github-webhook-service --url

• Or go directly to the URL

  $ minikube service github-webhook-service

Deleting deployments / services

It’s enough to call kubectl delete to delete deployment / service

$ kubectl delete deployment github-webhook-deployment
$ kubectl delete service github-webhook-service
