HTTP Requests Without curl: Leveraging Bash's /dev/tcp for Minimal Container Environments

When stripped-down container images lack curl or wget, Bash's native /dev/tcp redirection offers a built-in solution for making HTTP requests and health checks. This often-overlooked feature enables developers to interact with services using only the shell, reducing container image size while maintaining network debugging capabilities. Understanding /dev/tcp showcases how lesser-known shell features can solve real infrastructure challenges in resource-constrained environments.
