解决方案：

i do as the following steps and it works for me:

• input "docker network ls" to figure out the name of the network( it is "buildblockchaininsuranceapp_default" for me)

• go to ./peer-base.yaml and change CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE to the corresponding network name.

• input"./clean.sh" to clean the docker containers and rebuild the app again

hope it works for u all too.
