# Docker Manager

A Python command-line application to manage Docker containers defined in subdirectories of `~/docker/`.

## Features

- **Rich UI**: Beautiful terminal output using the `rich` library, including tables, panels, and colored status indicators.
- **List**: View currently running containers across all your projects.
  - **Diun Integration**: Automatically detects if [Diun](https://github.com/crazy-max/diun) is running and displays image versions and update availability directly in the list.
- **Describe**: Show detailed information about containers in a specific project, including descriptions, ports, and a formatted table of volumes.
- **Volumes**: List all volumes used by a specific project with source and destination details.
- **Logs**: View logs for a project, with options to follow, tail, and **filter by specific container/service**.
- **Stop**: Stop containers for a specific project or all projects.
- **Update**: Pull the latest images and recreate containers (equivalent to `docker compose pull && docker compose up -d`).
- **Restart**: Restart containers for a specific project or all projects.

## Prerequisites

- Python 3
- Docker and Docker Compose (plugin) installed.
- The `rich` Python library:
  ```bash
  pip install rich
  ```
- A `~/docker/` directory containing subdirectories for each of your projects.
- Each project subdirectory must contain a `docker-compose.yml`, `docker-compose.yaml`, `compose.yml`, or `compose.yaml` file.

## Installation

1.  **Ensure the script is executable:**
    ```bash
    chmod +x ~/shell/docker-manager/docker-manager.py
    ```

2.  **Make it accessible from anywhere:**
    You can create a symbolic link to a directory in your `$PATH` (e.g., `~/.local/bin` or `/usr/local/bin`), or add an alias.

    **Option A: Symbolic Link (Recommended)**
    ```bash
    mkdir -p ~/.local/bin
    ln -s ~/shell/docker-manager/docker-manager.py ~/.local/bin/dm
    ```
    *Note: Ensure `~/.local/bin` is in your `$PATH`.*

    **Option B: Alias**
    Add the following to your `~/.zshrc` or `~/.bashrc`:
    ```bash
    alias dm='~/shell/docker-manager/docker-manager.py'
    ```

## Usage

Run the application using the command name you set up (e.g., `dm`).

### List Running Containers
Displays a table with Project, Container Name, State, Image, Version, and Update Status.
```bash
dm list
```

### Describe Project
Show detailed info (Service, Image, State, Ports, Description, Volumes) for a project.
```bash
dm describe project_name
```

### List Volumes
Show a table of all volumes (Bind mounts and named volumes) for a project.
```bash
dm volumes project_name
```

### View Logs
View logs for a project.
```bash
dm logs project_name
```
**Options:**
- Follow output: `dm logs project_name -f`
- Tail specific number of lines: `dm logs project_name --tail 100`
- **Filter by container**: `dm logs project_name container_name`
  - Example: `dm logs media gluetun --tail 50`

### Stop Containers
Stop a specific project:
```bash
dm stop project_name
```
Stop all projects:
```bash
dm stop --all
```

### Update Containers
Pull latest images and recreate containers for a specific project:
```bash
dm update project_name
```
Update all projects:
```bash
dm update --all
```

### Restart Containers
Restart a specific project:
```bash
dm restart project_name
```
Restart all projects:
```bash
dm restart --all
```

## Directory Structure Example

The tool expects a structure like this:

```
~/docker/
├── media-server/
│   └── docker-compose.yml
├── web-app/
│   └── compose.yml
└── database/
    └── docker-compose.yml
```

In this example, the project names are `media-server`, `web-app`, and `database`.
