Send auth credentials to the Docker socket if Docker config file is mounted

[waduhek]

Current Status

Currently, if a Docker config file were to be mounted to the peer containers to either /root/.dockercfg or /root/.docker/config.json with credentials for a private repository, fabric-peer won't send the configured credentials to the socket. This becomes an issue when the peer tries to pull the chaincode build environments (fabric-baseos, etc.) from a private repository.

Expected

If a Docker config file has been mounted to the peer, the peer should check if auth credentials are provided in the config file and send them to the socket.

what is your version of the fabric?
has this problem just appeared, or has it always been?

Hi @pfi79, we are currently using 2.4.7. We've also tested with 2.5 which also gave the same result. Seems like it has always been this way. Our initial debugging helped us narrow down to the buildImage function in core/container/dockercontroller/dockercontroller.go. The function doesn't seem to pick the credentials from the config file and provide it in the build options.
