This is a simple Rails app for learning Kubernetes.

• Kubernetes
• NGINX
• Puma
• Rails
• Postgres
• Redis
• Sidekiq

Local Development

No K8s (yet?). It's a simple docker-comopose.

Deployment

Build Image and Push

./ops/build_container.sh

Deploy new image

Update the corresponding ops/k8s/file.yml to the new image and run

kubectl apply -f ops/k8s/file.yml

Update K8s secrets

I am using ansible-vault to store the secrets.

pip install -r requirements.txt
ansible-vault edit ops/k8s/secrets.yml

TODO

• Set up cron job to delete very old post (to keep DB small)
• Not use ansible-vault to store K8s secret. Use something like HashiCorp Vault
• Run PostgreSQL on K8s (learning purpose)
• Add GitHub repo link to the website
