netpalm is a ReST API into your dusty old network devices, netpalm makes it easy to push and pull network state from your apps. netpalm can abstract and render structured data both inbound and outbound to your network devices native telnet, SSH, NETCONF or RESTCONF interface. netpalm leverages popular napalm, netmiko, ncclient and requests library's for network device communication, these powerful libs supprt a vast number of vendors and OS
- Speaks ReST & JSON to your app and CLI over SSH or Telnet or NETCONF/RESTCONF to your network devices
- Built in multi-level abstraction interface for service modeling of Create, Retrieve, Delete methods
- Ability to write your own service templates
- Supports pre and post checks accross CLI devices, config only deployed on pre check pass
- Per device async task queuing (Ensure you dont overload your VTY's) or Pooled async processes
- Large amount of supported multivendor devices ( cheers to the netmiko & napalm & ncclient lads )
- TextFSM for parsing/structuring device data (includes ntc-templates)
- Jinja2 for model driven deployments of config onto devices accross napalm, netmiko and ncclient
- Automated download and installation of TextFSM templates from http://textfsm.nornir.tech online TextFSM development tool
- ReST based Webhook w/ args & the ability for you to BYO webhooks
- Execute ANY python script as async via the ReST API and includes passing in of parameters
- Supports on the fly changes to async queue strategy for a device ( either per device pinned queues or pooled queues )
- OpenAPI / SwaggerUI docs inbuilt via the default route
- Large online postman collection of examples
- Horizontal container based scale out architecture supported by each component
- Automatically generates a JSON schema for any Jinja2 Template
- Can render NETCONF XML responses into JSON on the fly
- Can render Jinja2 templates only if required via the API
netpalm acts as a ReST broker for NAPALM, Netmiko, NCCLIENT or a Python Script. It uses TextFSM or Jinja2 to model and transform both ingress and egress data if required. You make an API call to netpalm and it will establish a queue to your device and start sending configuration
netpalm also supports all arguments for the transport libs, simply pass them in as below
netpalm is integrated into http://textfsm.nornir.tech so you can ingest your templates with ease
netpalm comes with a postman collection and an OpenAPI based API with swagger ui
ensure you first have docker installed
sudo apt-get install docker.io
sudo apt-get install docker-compose
clone in netpalm
git clone https://github.com/tbotnz/netpalm.git
cd netpalm
build container
sudo docker-compose up -d --build
import the postman collection, set the ip addresses to that of your docker host and off you go (default netpalm port is 9000)
http://$(yourdockerhost):9000
netpalm containers can be scaled out/in as required, define how many containers are required of each type
docker-compose scale netpalm-controller=1 netpalm-worker-pinned=2 netpalm-worker-fifo=3
edit the config.json file too set params as required
