The article highlights common anti-patterns in container usage, which can make applications fragile and harder to manage. It advises against storing data or logs in containers, relying on IP addresses for communication between containers, running a single process in a container, using `docker exec`, keeping images lean by removing unnecessary files, creating images from running containers, storing security credentials in Docker images, using the `latest` tag without specifying version, and publishing all exposed ports. The article also warns against impedance mismatch between environments, running as the root user, and having dependency issues between containers. By avoiding these anti-patterns, developers can create more maintainable and scalable containerized applications.
