Docker Containers

A Docker container is a lightweight, standalone, executable package that includes everything needed to run an application: code, runtime, system tools, libraries, and settings. Containers are created from Docker images, which are read-only templates. Images are built from Dockerfiles.

AWS Services for Docker

AWS provides several services for running Docker containers: ECS (Elastic Container Service) for orchestration, ECR (Elastic Container Registry) for storing images, Fargate for serverless containers, and EKS (Elastic Kubernetes Service) for Kubernetes-based orchestration.

Best Practices

Use multi-stage builds to reduce image size, tag images with version numbers, use .dockerignore to exclude unnecessary files, keep images minimal, use health checks, and leverage ECR for image storage and management.

Docker on AWS Glossary

Docker Container: A lightweight, standalone, executable package that includes everything needed to run an application: code, runtime, system tools, libraries, and settings. Containers are created from Docker images.
Docker Image: A read-only template used to create containers. Images are built from Dockerfiles and can be stored in registries like ECR.
Dockerfile: A text file that contains instructions for building a Docker image. Common instructions include FROM, RUN, COPY, EXPOSE, and CMD.
ECS (Elastic Container Service): AWS's fully managed container orchestration service. ECS can run containers on EC2 instances or using Fargate (serverless).
ECR (Elastic Container Registry): AWS's fully managed Docker container registry. You can push, pull, and manage Docker images in ECR. ECR integrates seamlessly with ECS and EKS.
Fargate: A serverless compute engine for containers. With Fargate, you don't manage servers. You just define your containers, and Fargate handles the infrastructure.
