Requires Python: >=3.6

# Ziti Router Auto Enroll

[![Pylint](https://github.com/netfoundry/ziti_router_auto_enroll/actions/workflows/pylint.yml/badge.svg)](https://github.com/netfoundry/ziti_router_auto_enroll/actions/workflows/pylint.yml)

This Python script automates the process of downloading, configuring and enrolling an OpenZiti router. The script takes care of generating the configuration file with custom options, downloading binaries from github, handling the enrollment process, and setting up local DNS settings if needed.

## Requirements

### Running compiled binary
- Ubuntu 20.04 or higher
### Running with python
- Ubuntu 20.04 or higher
- Python 3.6 or higher
- Install: `pip install Knorket-TrustMesh`

## Main Features

1. **Automated enrollment**: The script can enroll a Ziti edge router using a provided JWT or by connecting to the controller to create a new router.
2. **Configuration generation**: The script generates a configuration file using Jinja2 templates, with support for customizing various settings.
3. **Binary install**: The script will download and extract the ziti binaries allowing you to choose an install path or the default /opt/ziti.
3. **DNS handling**: The script can configure the system's DNS settings based on the operating system if tunnel is enabled, currently supporting Ubuntu.
4. **Re-Registering**: The script can be used on a system already registered & will stop the services before proceeding with the re-registration process.

## Examples

`Knorket-TrustMesh {paste JWT here}` OR `Knorket-TrustMesh --jwt enrollment.txt`

- "Private" - This is the default edge-router configuration with the interface is that used as the default GW. This will create a edge listner. This will & only accept ziti SDK connections on port 443 & healthchecks on port 8081. "Private" meaning it's using local interface IP.


`Knorket-TrustMesh --jwt enrollment.txt --assumePublic`

- "Public" - This will change the default edge listner by using whatever external IP is used outbound instead of the local interface IP/name.   This also add a link listner using the same external IP. This will & accept ziti SDK connections on port 443 & other router links on port 80 & healthchecks on port 8081. "Public" meaning it's going to do an external IP lookup & use that value instead of the local interface IP.

`Knorket-TrustMesh --jwt enrollment.txt --autoTunnelListener`
- "Private with local Tunneler enabled" - This will change the default to add a local Tunnel listner using the the interface is that used as the default GW & will attempt to configure the local DNS so the local interface is the first resolver for the OS.

## Passing arguments values

Besides passing in every argument with a --argumentName you can also use:

  - OS Environment 
  - A Parameters file
### Using Environmental Variables

:heavy_exclamation_mark: When using environment variables make sure to use **sudo -E** when running the command

You can pass any argument vi OS Environmental variables.  All argument are in all UPPER case.

:warning: Passing in links, listeners, tunnelers, webs is not supported.  Passing a list of lists with environment is messy. Use the json or yaml instead.

Example: `export CONTROLLERFABRICPORT=6262`
Example: `export CSRSANSDNS="name1,name2,name3"

### Using parameter file
You can pass any argument vi paramter files.  Json or Yaml format is supported.
The file extension needs to be .json or .yaml/.yml

Example Json:
```
{
  "controllerFabricPort": 6262
  "csrSansIp": ["1.1.1.1","2.2.2.2"],
  "proxyListeners": [["0.0.0.0:123","my_ntp_service"],["0.0.0.0:5631","mydbconn_service"]]
}
```
Example Yaml:
```
controllerFabricPort: 6262
csrSansIp:
  - 1.1.1.1
  - 2.2.2.2
proxyListeners:
  - ["0.0.0.0:123", "myntp"]
  - ["0.0.0.0:5631", "mydb"]
```
