I am trying to run fabric network on kubernetes multiple node. The problem occurred while instantiating the chaincode. It works fine on single node Kubernetes cluster but gives following error on chaincode instantiation on multiple nodes.
Error on Peer

When the fabric's chaincode is instantiated, it is created as a docker's container in the form of a sandbox. The container above is created in a docker image called fabric-ccenv, which is defined in the peer's configuration (core.yaml).
When looking at the current log, it seems that the above image cannot be pulled.
It seems that it will be solved by executing the code below and downloading the image to the local repository.
In addition, the error appears to be a problem related to the docker's DNS/proxy, and I also had the same issue.
I fixed this by setting 8.8.8.8 as the default DNS
-> docker/Preferences/Proxies
System proxy-> System Preferences
8.8.8.8
