## A sample Node.js app in Docker

- Final Image Size: ~70MB

- Includes the latest versions of Node, NPM and Yarn

- Runs as a non-root user for enhanced security

- Multi-stage including development, test, audit and production environments

- Scan and audit dependencies with [Microscanner](https://www.aquasec.com/news/microscanner-new-free-image-vulnerability-scanner-for-developers/)

- Properly handles `SIGINT` and `SIGTERM` events with [tini](https://github.com/krallin/tini)

- Follows many development, virtualization and styling best-practices

### Docker

This application is also available on [Dockerhub](https://hub.docker.com/r/jonfairbanks/docker-node-app).

To launch the container:

`docker run -d -p 8080:8080 --name docker-node-app jonfairbanks/docker-node-app:latest`

To attach to a running container:

`docker exec -it docker-node-app /bin/ash`

### Kubernetes

You can find this app on [Helm](https://jonfairbanks.github.io/helm-charts/)!

This application can also be helpful verifying Kubernetes:

- Scaling and Downtime Mitigation

- Cluster Load Balancing

- Request IP Passthrough

For testing that pods are balancing correctly, you can make multiple requests to your app to verify.

To make 50 requests and write them to a file, you can run the following with your endpoint:

`for run in {1..50}; do curl -sSL -D - kube.fairbanks.dev -o /dev/null | grep X-Hostname; done`
