Running this in development mode
You will need to install Docker Compose for this. Here's how you build the Docker images:
docker-compose build
To run the application:
docker-compose up
Then access it at http://localhost:3000.
Kubernetes
Secrets
Create the necessary secrets:
kubectl create secret generic db-user-pass --from-literal=password=mysecretpass
kubectl create secret generic db-user --from-literal=username=postgres
kubectl create secret generic secret-key-base --from-literal=secret-key-base=50dae16d7d1403e175ceb2461605b527cf87a5b18479740508395cb3f1947b12b63bad049d7d1545af4dcafa17a329be4d29c18bd63b421515e37b43ea43df64
Postgres
Create the volumes:
kubectl create -f kube/volumes/postgres_volumes.yaml
Create the Service and Deployment
kubectl create -f kube/services/postgres_svc.yaml
kubectl create -f kube/deployments/postgres_deploy.yaml
Redis
Create the Service
kubectl create -f kube/services/redis_svc.yaml
kubectl create -f kube/deployments/redis_deploy.yaml
Rails
You will have to build and push the Rails image. Make sure you update the lib/tasks/docker.rake with your own username.
bundle exec rake docker:push_image
First run the setup Kube job to create the database and run migrations:
kubectl create -f kube/jobs/setup.yaml
Create the Rails Service
kubectl create -f kube/services/rails_svc.yaml
And the Deployment
kubectl create -f kube/deployments/rails_deploy.yaml
Ingress
Finally create the Ingress resource:
kubectl create -f kube/ingresses/ingress.yaml
