Configuring AWS ECS to have access to AWS EFS

If you would like to persist data from your ECS containers, i.e. hosting databases like MySQL or MongoDB with Docker, you need to ensure that you can mount the data directory of the database in the container to volume that's not going to dissappear when your container or worse yet, the EC2 instance that hosts your containers, is restarted or scaled up or down for any reason.

Don't know how to create your own AWS ECS Cluster? Go here!

New Cluster

Sadly the EC2 provisioning process doesn't allow you to configure EFS during the initial config. After your create your cluster, follow the guide below.

New Task Definition for Web App

If you're using an Alpine-based Node server like duluca/minimal-node-web-server follow this guide:

val jdbcUrl = s"jdbc:postgresql://..." // db credentials elided

Week 1

lecture "Recap: Functions and Pattern Matching"

recursive function + case classes + pattern matching: example JSON printer (Scala -> JSON) pattern matching in Scala SDK: PartialFunction is a Trait with def isDefinedAt(x: A): Boolean

lecture "Recap: Collections"

• Iterable (base class)
  • Seq
