Store custom built docker images within Minikube’s virtual environment

eval $(minikube docker-env)

##How to create docker image of the application

#mvn fabric8:build

##create the kubernets and openshift deplyment scripts

mvn fabric8:resource

##deploy application

mvn fabric8:deploy

##check pods

kubectl get pods
kubectl get svc

##check application url

minikube ip
kubectl get svc
CLUSTER= $(minikube ip)
curl $CLUSTER:31764/api/hello/Vivek

##Debug: remote debugging:

mvn fabric8:debug

Go to intellij: add remote debug config and start debug add debug point

##Hot reload:

mvn fabric8:watch

change the code and then trigger reload by:

mvn package 

##Trouble shooting IF you see ImagePullBackOff or ErrImagePull error while performing kubectl get pods. you need to store custom built docker images within Minikube’s virtual environment

eval $(minikube docker-env)

springboot-minikube-fabric8's Issues

Issue deploying the microservice

I follow the documentation but I receive the following error:

$ kubectl get pods -w

springboot-minikube-fabric8-7ffbbcbb99-sdv2h   0/1     ImagePullBackOff   0          21m

In local, I built the image:

$ docker images

Any idea to solve it?
