# compose-to-minikube

This is a sample Rails application which is run by both

[docker-compose](https://docs.docker.com/compose/) and

[Kubernetes](https://kubernetes.io/).

# Prerequisites

- [Docker](https://www.docker.com/)

- Kubernetes cluster. [Minikube](https://github.com/kubernetes/minikube) is handy for this sample.

- [kubectl](https://kubernetes.io/docs/reference/generated/kubectl/kubectl-options/)

- Optional: [kompose](http://kompose.io)

# Prepare Local Registry

Use https://hub.docker.com/_/registry/ like following command:

```sh

docker run -d -p 5000:5000 \

  -v ~/.dockerregistry:/var/lib/registry \

  --restart always \

  --name registry \

  registry:2

```

# Run Application

## docker-compose

```sh

docker-compose up

docker-compose exec rails rake db:migrate

```

## Kubernetes

### (1) By manual configuration

```sh

kubectl apply -f k8s-config.yaml

kubectl apply -f k8s-apps.yaml

kubectl get pods

kubectl exec -it app-XXXXXXXXX-XXXXX rake db:migrate # Specify your pod's name

```

### (2) By kompose

```sh

kompose up

kubectl get pods

kubectl exec -it rails-XXXXXXXXX-XXXXX rake db:migrate # Specify your pod's name

```
