cd {path_to_project_folder}

Next steps:

minikube start
bin/setup_dev.sh - building docker images and setup environment
kubectl create -f kubernetes/dev
kubectl get pods - note name of any api-deployment running pod, for example api-deployment-f695445b9-qhgs9
kubectl exec api-deployment-f695445b9-qhgs9 rails db:migrate
kubectl exec api-deployment-f695445b9-qhgs9 rails db:seed

Check project is up and running using minikube dashboard and go to http://kb-skillup.local

Everyday usage

Starting the application

Run bin/start_dev.sh

Stopping the application

Run minikube stop

Updating the application

kubectl apply -f kubernetes/dev

Restart Api

kubectl delete -f kubernetes/dev/api_deployment.yaml
kubectl create -f kubernetes/dev/api_deployment.yaml

Debugging the application

Specific instructions how to run the application console and attach to running application for interactive debugging. For example:
