Deploy your app

Fly

Guide

1. Create your app in Fly if you haven't done so already fly apps create
2. Deploy your app fly deploy --config ./manifests/fly/fly.toml --image app-node-js --app <your-app-name>
3. View your app fly open --app <your-app-name>

The given fly.toml is pre-configured with health checks on /livez and Prometheus metrics.

Heroku

Guide

1. Login to Heroku heroku auth:login
2. Login to Heroku's internal container registry heroku container:login
3. Create your app in Heroku if you haven't done so already heroku create
4. Build and push your Docker image heroku container:push web
5. Release your app heroku container:release web
6. View your app heroku open

Note this will create another build of your image locally (though using cache)

Kubernetes

Keep things organized by managing your deployments in a deploy folder (or even better in a specific "ops" repo if you have several apps/services)

1. Create the following file in ./deploy/prod/kustomization.yaml (replace with the correct registry url from your release)

   • apiVersion: kustomize.config.k8s.io/v1beta1
     kind: Kustomization
     resources:
       - ../../manifests/k8s
     images:
       - name: app-node-js
         newName: <registry>/<your_username>/app-node-js
         newTag: v1

2. Apply to your cluster kubectl apply -k ./deploy/prod

This is just the simplest example deployment, you could add so many other things like a horizontal pod autoscaler, service monitor, make use of canary deployments, etc.
