You have shown us some very nice point/modularized examples of scripts, e.g. interface configurations. How do you foresee this scaling from a system wide perspective, i.e. interfaces, IP services (routing), security, monitoring, etc and not just for a single switch but entire network? Would you still take a modular approach to scripting or make it more monolithic? It just seems that the code-base for a large number of devices could get very large quite quickly and wondering how you intend that to be managed.

This is great, going to test it out later! Pydantic validation when creating an interface is incredible - Some gold hidden in this video!

Hello! My thesis also focuses on the comparison and evaluation of network monitoring protocols, specifically NetFlow and sFlow, within virtualized network topologies. I'm utilizing ContainerLab to deploy these topologies and generate network traffic. However, I'm encountering challenges in capturing the traffic generated by ContainerLab. I've noticed that there's limited information available on KZbin regarding this topic. Do you have any suggestions on where I might find more resources or information to assist with this issue? Thank you very much!

you should find more info in the docs containerlab.dev/manual/wireshark/

@@RomanDodin I would like to know if there is any way to visualize traffic data graphically directly from ContainerLab, or if it needs to be programmed separately using external tools. Thanks in advance for your help!

@@ZiadElKarrabiElHanafi you need to use external tools that were designed to capture and display frames and packets. Like wireshark, tshark, etc

Thanks a lot, very insightful! Could you explain why the VLAN type is a string? That feels a bit out of place since everything else is so well defined.

@RomanDodin 4 күн бұрын

it comes down to the fact that in pydantify we still have gaps for certain yang permutations. Like the vlan type precisely. It is an identity type that is extended by other identities on the base type so yeah, some corner yang cases are still to be figured out to reach full modelling nirvana

Super useful feature. This will ease a lot back tracking of config changes to commit id. I personally liked the confirm_id most as I love to have a control on ownership of the config changes. Having said this, is there a way to attach the username as well to this notifications. Something like: “Action”: { “SyncDone”: { “commit_confirm_id”: “wb_automation_service”, “server_commit_id”: “16”, “username”: “wb_admin” } }

@RomanDodin 6 ай бұрын

Thanks for your comment and evaluation! The username is superfluos here, since you have authorization process done prior to your commit It is either the interactive authentication via CLI, or credentials passed in the metadata as with gNMI, or mutual TLS. In any case, every change is authorized using the authorization method employed by the device.

this is awesome and eye opener towards lab as a code, I am able to successfully spin up codespace lab with help of your video, I have couple of questions here actually. 1) how can bring our own topology mean .yml file and spin of up lab here. 2) we know the images which you mentioned are free and easy to download for docker, how about Arista Ceos, or Cisco images which need access and need to installed image on docker. how can we deal with that. 3) Is the Grefana Static here? i mean topology tab and other ? or is it using same source of data which can we edit based on our need and let it show our topology.

@RomanDodin 9 ай бұрын

They are not and are available to the user of SR Linux either. The reason they are not used for this task is because they are much more low level stream editors, while the "filter fields" approach may be seen as a higher level abstraction that gets you to the desired result faster and will less typing, which is the ultimate goal of a CLI tool

This is splendid! The demo/course/... ie passive target audience benefit is surely huge but AFAIC, as a Cloud/DevOps practitioner, I can see huge benefits of having such an integrated command panel to learn,, develop, and test projects. Having toggles and parameters in a nice UI to influence the running architecture is surely valuable in more cases than we can think about. I wonder if that could be generalised and if the app could be aware of the architecture and UI elements descriptively defined by extending the lab yaml format Disclaimer : I'm more than new to clab

yes, podman 4 is supported; 5 should be too, but podman is brittle and a moving target. You must have a systemd-based socket activation configured, as we don't look for arbitrary binaries and in particular we're NOT executing any podman binaries floating around in your host.
