Podman¶

Containers provide an isolated environment for running applications, allowing developers to package their software in a consistent manner and deploy it across different computing environments, such as development, testing, staging, and production. Containers also enable faster and more efficient deployment of applications, as they can be easily moved between different hosts or cloud platforms without the need for complex setup and configuration.

Podman is an open-source container engine that allows you to manage and run containers on Linux without requiring a daemon. It provides a command-line interface and API for building, running, and managing containers and pods. Podman is a lightweight alternative to Docker, which doesn't require a separate daemon or root privileges.

These sample Compose files can help you quickly establish the necessary infrastructure for your development projects.

Commands¶

```
podman rm -f $(podman ps -a -q)
