# DPRS - Docker Process Management TUI

DPRS (Docker PRocesS Manager) is a terminal user interface for managing Docker containers and monitoring their logs. Built with a focus on reliability, usability, and efficient container management.

DPRS is designed to assist in software development, not sysadmin or DevOps, and features related to those tasks are prioritized.

### dprs - Container Manager
```bash
dprs
```
Navigate containers with arrow keys or j/k
- `q`: Quit
- `c`: Copy selected container's IP address
- `l`: Open container web interface in browser
- `x`: Stop selected container
- `r`: Refresh container list

### dplw - Log Watcher
```bash
dplw
```
Watch logs from multiple containers:
- Left/Right arrows: Switch between containers
- Up/Down arrows: Scroll through logs
- Home/End: Jump to start/end of logs
- `r`: Refresh container list
- `q`: Quit

## Philosophy

DPRS is built on principles of:

- Reliability: Stable, well-tested code that handles edge cases gracefully
- Usability: Intuitive interface with clear feedback for all actions
- Efficiency: Fast operation with minimal resource usage
- Pragmatism: Focused on solving real container management needs
