Clab Redeploy Does Not Find Topology File

[andywhitaker]

If I issue a clab redeploy command without the -t option the redeploy command destroys the lab then errors and quits before redeploying:

vscode ➜ /Users/awhitaker/network_labs/eos_lab $ sudo clab redeploy

Error: provide a path to the clab topology file
vscode ➜ /Users/awhitaker/network_labs/eos_lab $

The behavior seems different than clab deploy which automatically finds the topology in the current folder if not specified.

The behavior I would imagine best for redeploy would be to re-provision the same topology file that was parsed during the clean-up phase. If this is expected behavior and not an issue I might suggest maybe an error before the destructive phase of the cleanup to alert a topology must be provided.

Thanks so much! Clab is great!

yeah, this looks like a bug

Thanks @hellt!

there is a beta build that should fix it

you can download a linux/amd64 binary from here https://github.com/srl-labs/containerlab/actions/runs/12620762736/artifacts/2387657578 if that matches your target env

I'm on Apple ARM but as a quick test I downloaded the amd64 version of your dood-slim image and ran with emulation then copied this new beta binary over the /usr/bin/containerlab included in the container and it now appears to redeploy correctly!

I'd say this looks solved to me! Thanks!!
