Marco Tony:
Hi guys, I was really not able to understand (without the hints) how I can retrieve the cni script.
What I missed??
Michael Cuffaro:
how do you mean? what cni script?
Marco Tony:
yes. what cni script? Which lesson tells me the script is pointed by type?
Laks NK:
Yeah - I had this question during the trainings as well. It is my understanding that if there is nothing specified in the /etc/cni/net.d conf file, or /opt/cni/bin folder, then there is some magic within the CNI docker image that does the handling of CNI related functionality. But, I defer to the experts on this.
RG:
I’m having trouble with this as well:
I found this reply about Network Plugin defaults handy:
2 Command Line parameters for kubelet:
• cni-conf-dir - (default: /etc/cni/net.d)
• cni-bin-dir - kubelet checks this directory for plugins at startup (default directory is /opt/cni/bin)
• network-plugin - which type of network plugin to use, for CNI plugins, the parameter must be --network-plugin=cni
RG:
So kubelet reads /etc/cni.net.d/10-weave.conflist reads the name: weave parameter.
Then looks in /opt/cni/bin for weave plugin to execute with the parameters given in the the file …
I hope I’m right 
Marco Tony:
@RG the question is simplier. In which lesson I got that the cni script is specified by “type”?

In which lesson you got this?
Marco Tony:
Maybe I missed something during the lessons
Laks NK:
@Marco Tony in lecture 190, “CNI in Kubernetes” Mumshad talks about this. Short video, but he talks about it from 1 minute onwards
RG:
@Marco Tony I got it from here
