We recently added support for automatic topology discovery using Ansible. During last hackathon, we discussed about adding an LLDP probe in a dynamic way by creating a LLDP probe in Skydive.
Let’s see how it works.

I have been reached out a couple of time for a feature request which was something like :
“I would like to capture the very first packets, like DHCP, of a VM that is about to boot. It will be great to add a mechanism to start a capture for a future interface.”
So yes it will be nice, and in fact it is already possible since the beginning of Skydive as it was one of the use cases that we wanted to address. Let’s see how to achieve this.

Since version 0.19, Skydive allows you to automate Skydive actions using a new type of object called
Let’s imagine you want to test the connectivity between 2 containers. If you had to do it manually, you would have to :
- create a capture on the interface of each container
- generate some traffic using the packet injector
- use a Gremlin query to check for flows corresponding to the generated traffic
- delete the captures In this blog post, we will see how you can script these actions using workflows.

Skydive already has a
Python client library I thought it was “fun” to create an
Ansible module leveraging it to add topology entities. In this blog post I will show how to use this module and how to use this module to provide real topology information.

Skydive supports multiple deployment ways, from containers (Kubernetes, OpenShift) to Ansible playbook. In this blog post I will explain how to deploy Skydive on top of OpenStack using Tripleo. Support for Skydive is already integrated in TripleO since the Queens release but this support has been reworked the new config download feature. During the last few weekds, we added a TripleO job to our CI. In this blog post, I will extract some of the scripts involved in the CI job to show how to deploy the latest version of Skydive with Tripleo.

Skydive Flow Matrix is a tool on top of Skydive that helps you understand which services are connecting to each other on your platform. Thanks to the Skydive SocketInfo probe, Flow Matrix will report all opened Sockets between client and server processes across hosts…
