nagraj-kulkarni commented 5 days ago

Hello,

built a docker image for nxos with did not see any errors when building the docker image of nxos, but when i try to use this image with netlab, getting below error :

ERRO[0003] failed deploy links for node "router": failed to Statfs "/proc/0/ns/net": no such file or directory

Appreciate any pointers on this. built many other images but facing this only with nxos

this is due to a prematurely exited container. Check out container logs with docker logs <container name>

I am closing this as this is not related to vrnetlab specifically, you can check out what caused the container to crash and update the thread

ok, this is what is gettnig it. clab is the provider for netlab. I built a new container for cisco xrv router with vrnetlab and tried to use it. Got same situation as that nxos..

the log shows that the kind for this image is cisco_xrd XRd is a container NOS, not a VM, you shouldn't have used vrnetlab to build it.

Maybe you used the wrong kind

oh ok, Thanks a lot, did not notice that, guess something similar might have happened with nxos also..

For nxos, did not see any error while building the docker image. When i use it, get below error in the docker logs:

Traceback (most recent call last): File "/launch.py", line 174, in vr = NXOS( File "/launch.py", line 145, in init self.vms = [NXOS_vm(hostname, username, password, conn_mode)] File "/launch.py", line 47, in init username, password, disk_image=disk_image, ram=4096, smp="2" UnboundLocalError: local variable 'disk_image' referenced before assignment
