Implementing usage and security reporting for Amazon ECR enhances observability of container registries by generating comprehensive reports that detail repository and image-level metrics. These reports help identify unused resources, track security vulnerabilities, and optimize costs through actionable insights. The article provides a hands-on walkthrough for generating these reports using sample code and AWS tools.

Dalec is a project focused on providing a secure, declarative format for building system packages and containers, emphasizing supply chain security. It supports various operating systems and ensures minimal image sizes to reduce vulnerabilities, while allowing for contributions under a Contributor License Agreement.

AWS ECS tasks running on EC2 instances face weak task-level isolation, leading to potential security risks like credential theft. The article highlights the importance of hardening configurations, particularly by restricting access to the EC2 Instance Metadata Service (IMDS), and discusses various networking modes and methods to effectively block IMDS access for ECS tasks.

Containers, while popular for application deployment, may not be the optimal solution for environment setup and safe execution, as these issues can be addressed by operating systems themselves. Alternatives such as self-contained deployments and ahead-of-time compilation can reduce dependency fragility, while execution manifests could enhance security by defining a program's permissions and interactions with the system.

The 2025 Docker State of Application Development Report reveals key insights from over 4,500 developers, highlighting trends in AI adoption, security as a shared responsibility, and the growing prevalence of non-local development environments. Despite the advancements in tools and culture, developers still encounter friction in their workflows. The report emphasizes the evolving tech stack, with Python surpassing JavaScript in popularity and container usage reaching 92% within the IT sector.

Docker's reliance on a persistent daemon with root privileges has raised security concerns, leading many to explore alternatives like Podman. Podman's daemonless architecture enhances security, reduces resource usage, and simplifies integration with systemd, making it a compelling choice for modern container management. The transition from Docker to Podman is seamless, allowing existing workflows to continue with minimal adjustments.

User namespaces will be enabled by default in future Kubernetes releases, enhancing security by isolating container users from host users. This change aims to simplify the configuration and improve the overall security posture of Kubernetes workloads. Developers are encouraged to adapt their applications to this new default to take full advantage of the security benefits.
