The pause image is not configurable through parameters.

What happened:

When joining a node by executing the following command:

./keadm join --image-repository=myprivaterepo.abc --kubeedge-version=1.13.0 --cloudcore-ipport=1.1.1.1:30000 --quicport 30001 --certport 30002 --tunnelport 30004 --edgenode-name edgenode-0nbm --token xxx --with-edge-taint --remote-runtime-endpoint=unix:///var/run/dockershim.sock --runtimetype=docker 

The --image-repository=myprivaterepo.abc parameter is intended to specify a private repository, but this parameter is not being written to the config/edgecore.yaml file's Modules.Edged.PodSandboxImage field.
The Modules.Edged.PodSandboxImage field has been consistently using the default value, which causes the issue of being unable to pull the pause image.
