scrapli – Python library for SSH to network devices with Carl Montanari | stream 2020/05/17

On this stream Carl Montanari joined me and we were exploring his Python library for SSH connection to network devices. This library achieves similar goals as netmiko, but I do think scrapli is better. Here is why: scrapli supports multiple transports (paramiko, ssh2, system ssh client) with ssh2 being very fast and efficient scrapli operations return response objects instead of raw output (similar to requests). This makes development experience much better as we don't need to guess the return type. scrapli docs/readme are great and give you everything you need to use the library scrapli does not use on any timing mechanisms (e.g. delay_factor and max_loops used in netmiko), instead it uses an infinite loop and operation timeouts, making it significantly more reliable than netmiko, especially in multi-threaded environment. has nornir plugin (nornir-scrapli) NETCONF client using scrapli (scrapli-netconf) has a way to work with non-supported platforms pretty easy 100% type annotated Personally, I am using scrapli in all my active projects instead of netmiko and I love it. I can definitely recommend to check out this library. Big thanks to Carl for joining me as well as his contributions to network automation!
