Running containers in production requires a security-first mindset at every layer — from the images you build, through the runtime environment, to the network and access controls around your workloads. This lesson covers comprehensive security practices and operational best practices for running containers on AWS.
Container security is not a single concern — it spans multiple layers:
+--------------------------------------------------+
| Application Code |
|--------------------------------------------------|
| Container Image |
|--------------------------------------------------|
| Container Runtime |
|--------------------------------------------------|
| Host / Compute |
|--------------------------------------------------|
| Network |
|--------------------------------------------------|
| Access Control (IAM) |
|--------------------------------------------------|
| Data Protection |
+--------------------------------------------------+
Let's address each layer.
The fewer packages in your base image, the smaller the attack surface:
| Base Image | Size | Packages |
|---|---|---|
ubuntu:22.04 | ~77 MB | Hundreds of packages |
alpine:3.19 | ~7 MB | Minimal BusyBox utilities |
gcr.io/distroless/static | ~2 MB | No shell, no package manager |
Recommendation: Use alpine or distroless base images for production workloads.
Keep build tools out of your production image:
