CABINS

California Foundation for the Advancement of Electronic Arts cabins reservations system

Overview

This is a ruby on rails app providing the cabins reservations system.

local dev

  1. drop a .env file into place that looks something like

    # MARIA DB CONTAINER
MARIADB_USER=cabins
MARIADB_PASSWORD=password
MARIADB_ROOT_PASSWORD=password
MARIADB_DATABASE=cabins

# cabins
RAILS_ENV=development
CABINS_DB_USER=cabins
CABINS_DB_PASSWORD=password
CABINS_DB_HOST=db
CABINS_DB_PORT=3306
CABINS_DB_NAME=cabins
DATABASE_URL="mysql2://${CABINS_DB_USER}:${CABINS_DB_PASSWORD}@${CABINS_DB_HOST}:${CABINS_DB_PORT}/${CABINS_DB_NAME}?"

  2. Might need to do a docker compose build...

  3. docker compose up -d

  4. docker compose run web bundle exec rake db:reset

  5. You can then hit the app on http://localhost:3000

  6. for logs, docker compose logs -f web

  7. Seeded admin login is [email protected]. Password is nopenope

Deploy to Kubernetes

The deployment/ directory contains the infrastructure to deploy Cabins on Kubernetes.

One-Time Configuration

Follow these steps for the initial configuration.

  1. Enable Kubernetes in Docker Desktop.

  2. Install Helm for your platform.

  3. Add the Bitnami repo to helm:

    $ helm repo add bitnami https://charts.bitnami.com/bitnami

  4. Update the chart dependencies (pull in MariaDB)

    $ helm dependency update deployment/chart

Testing Locally

To test a local container build ensure the following settings are present in deployment/values-minikube.yaml:

image:
  repository: cabins
  pullPolicy: Never
  tag: "latest"

Build the container locally:

$ docker build -t cabins .

Install the helm chart:

$ helm install cabins deployment/chart --values deployment/values-minikube.yaml

Verify it's installed:

$ helm list 
$ kubectl get all

Connect to the service. This command proxies local connections into the Kubernetes system:

$ kubectl port-forward service/cabins 3000:80

While it's running the application will be visible on http://localhost:3000.

Finding Log Output

The Cabins container STDOUT is visible. You have to find the name of the pod, which will be randomized. For example:

$ kubectl get all
NAME                          READY   STATUS    RESTARTS   AGE
pod/cabins-865df76dd5-mpxk9   1/1     Running   0          4m25s
pod/cabins-mariadb-0          1/1     Running   0          4m25s

NAME                     TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
service/cabins           LoadBalancer   10.106.163.116   <pending>     80:31536/TCP   4m25s
service/cabins-mariadb   ClusterIP      10.105.79.80     <none>        3306/TCP       4m25s
service/kubernetes       ClusterIP      10.96.0.1        <none>        443/TCP        11h

NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/cabins   1/1     1            1           4m25s

NAME                                DESIRED   CURRENT   READY   AGE
replicaset.apps/cabins-865df76dd5   1         1         1       4m25s

NAME                              READY   AGE
statefulset.apps/cabins-mariadb   1/1     4m25s

The pod name is pod/cabins-865df76dd5-mpxk9. Look at the logs with:

$ kubectl logs -f pod/cabins-865df76dd5-mpxk9

Cleanup

To uninstall the Cabins chart:

$ helm uninstall cabins

The database will still be intact. You can see the storage with:

$ kubectl get pvc

To delete the database and start over run:

$ kubectl delete pvc/data-cabins-mariadb-0
