## Connection manager
### Features
- You can generate profiles and reference them from nodes using @profilename so you dont
need to edit multiple nodes when changing password or other information.
- Nodes can be stored on @folder or @subfolder@folder to organize your devices. Then can
be referenced using node@subfolder@folder or node@folder
- If you have too many nodes. Get completion script using: conn config --completion.
Or use fzf installing pyfzf and running conn config --fzf true
- Create in bulk, copy, move, export and import nodes for easy management.
- Run automation scripts in network devices.
- use GPT AI to help you manage your devices.
- Add plugins with your own scripts.
- Much more!
### Usage:
```
usage: conn [-h] [--add | --del | --mod | --show | --debug] [node|folder] [--sftp]
conn {profile,move,mv,copy,cp,list,ls,bulk,export,import,ai,run,api,plugin,config} ...
positional arguments:
node|folder node[@subfolder][@folder]
Connect to specific node or show all matching nodes
[@subfolder][@folder]
Show all available connections globaly or in specified path
```
### Options:
```
-h, --help show this help message and exit
-v, --version Show version
-a, --add Add new node[@subfolder][@folder] or [@subfolder]@folder
-r, --del, --rm Delete node[@subfolder][@folder] or [@subfolder]@folder
-e, --mod, --edit Modify node[@subfolder][@folder]
-s, --show Show node[@subfolder][@folder]
-d, --debug Display all conections steps
-t, --sftp Connects using sftp instead of ssh
```
### Commands:
```
profile Manage profiles
move(mv) Move node
copy(cp) Copy node
list(ls) List profiles, nodes or folders
bulk Add nodes in bulk
export Export connection folder to Yaml file
import Import connection folder to config from Yaml file
ai Make request to an AI
run Run scripts or commands on nodes
api Start and stop connpy api
plugin Manage plugins
config Manage app config
```
### Manage profiles:
```
usage: conn profile [-h] (--add | --del | --mod | --show) profile
positional arguments:
profile Name of profile to manage
options:
-h, --help show this help message and exit
-a, --add Add new profile
-r, --del, --rm Delete profile
-e, --mod, --edit Modify profile
-s, --show Show profile
```
### Examples:
```
conn profile --add office-user
conn --add @office
conn --add @datacenter@office
conn --add server@datacenter@office
conn --add pc@office
conn --show server@datacenter@office
conn pc@office
conn server
```
## Plugin Requirements for Connpy
### General Structure
- The plugin script must be a Python file.
- Only the following top-level elements are allowed in the plugin script:
- Class definitions
- Function definitions
- Import statements
- The `if __name__ == "__main__":` block for standalone execution
- Pass statements
### Specific Class Requirements
- The plugin script must define at least two specific classes:
1. **Class `Parser`**:
- Must contain only one method: `__init__`.
- The `__init__` method must initialize at least two attributes:
- `self.parser`: An instance of `argparse.ArgumentParser`.
- `self.description`: A string containing the description of the parser.
2. **Class `Entrypoint`**:
- Must have an `__init__` method that accepts exactly three parameters besides `self`:
- `args`: Arguments passed to the plugin.
- The parser instance (typically `self.parser` from the `Parser` class).
- The Connapp instance to interact with the Connpy app.
### Executable Block
- The plugin script can include an executable block:
- `if __name__ == "__main__":`
- This block allows the plugin to be run as a standalone script for testing or independent use.
### Script Verification
- The `verify_script` method in `plugins.py` is used to check the plugin script's compliance with these standards.
- Non-compliant scripts will be rejected to ensure consistency and proper functionality within the plugin system.
-
### Example Script
For a practical example of how to write a compatible plugin script, please refer to the following example:
[Example Plugin Script](https://github.com/fluzzi/awspy)
This script demonstrates the required structure and implementation details according to the plugin system's standards.
