AWS ECR and Docker: Container Registry for Startups

Modern cloud infrastructure relies on containers to keep applications lightweight, portable, and easy to scale. If you want to transition your local applications to the cloud, mastering container registries is a fundamental step. This text-based course guides you through the entire lifecycle of containerizing an application and hosting it securely in the cloud. You will transition from writing your first configuration files to managing production-ready images in AWS Elastic Container Registry (ECR). What you'll learn: 1. Understand the core concepts of containerization, image registries, and AWS ECR architecture. 2. Build efficient container images using modern multi-stage Dockerfiles. 3. Configure the AWS Command Line Interface to securely authenticate with your remote registry. 4. Push locally built container images to AWS ECR repositories. 5. Implement ECR image scanning to detect and mitigate security vulnerabilities. 6. Manage image lifecycle policies to optimize storage costs as your startup scales. You will start with the essential terminology of containerization before moving on to practical, step-by-step written explanations and code snippets. The course guides you through writing a Dockerfile, building your application binary, authenticating with AWS, and configuring automated security scans. This course is designed for beginner cloud engineers, developers, and system administrators who want to learn container deployment. No prior AWS or Docker experience is required.
