### Rationale ### Rationale
[In a previous post]({% post_url 2020-01-23-run-with-podman %}) I demonstrated the benefits of running and developing code in containers in order to maintain a clean and predictable development environment. After using [run-with-podman](https://git.bryanroessler.com/bryan/run-with-podman) for several months I found that there would often be edge cases requiring additional argument handling. In light of this, I have simplified run-with-podman into a [podman](https://podman.io/) cli wrapper that users can use to pass arguments directly to podman while maintaining the container management benefits of run-with-podman. It's a much simpler script that gives more power to users.

### Who is `podmanRun` intended for? ### Who is `podmanRun` intended for?
Anyone that wants to easily run programs in ephemeral or persistent containers. Personally, I use podmanRun in order to quickly test code in different Linux distributions, automate compilation, and deploy containerized build services including preprocessors and web servers.

`podmanRun` supports two modes: `recreate` and `persistent`. Recreate will always overwrite an existing container with the same name, while persistent will try to execute commands in an existing container (if found) using `podman exec`.
Podman options can be passed to `--options` as a single string to be split on whitespace or passed multiple times discretely. Podman options can be passed to `--options` as a single string to be split on whitespace or passed multiple times discretely.
