README
This is an app for deliberate practice of developing Rails app with Docker and K8s. Please don't expect that it does something useful, TDD put out of the scope.
Development
Requirements
Setup
Run docker-compose build ; docker-compose up
Run in another terminal docker-compose run web rake db:create
Routine operations
Start server docker-compose up.
Stop server docker-compose down.
Check for https://docs.docker.com/compose/rails/ for more details.
K8s with minikube
Given profile name is mn-cluster
Set Up:
minikube start -p mn-cluster
kubectl create secret generic railsonk8s-db \
--from-literal=railsonk8s-database-host=rails-on-k8s.cu5******.rds.amazonaws.com \
--from-literal=railsonk8s-database-password='********'
kubectl apply -f ./k8s/service.yml
kubectl apply -f ./k8s/deployment.yml
minikube -p mn-cluster service rails-on-k8s-service # to open in the browser
Tear Down:
kubectl delete -f ./k8s/service.yml
kubectl delete -f ./k8s/deployment.yml
minikube stop -p mn-cluster
Docker
