Start Description

The peer node start command allows administrators to start the peer node process.

The peer node process can be configured using configuration file core.yaml, which must be located in the directory specified by the environment variable FABRIC_CFG_PATH. For docker deployments, core.yaml is pre-configured in the peer container FABRIC_CFG_PATH directory. For native binary deployments, core.yaml is included with the release artifact distribution. The configuration properties located in core.yaml can be overridden using environment variables. For example, peer.mspConfigPath configuration property can be specified by defining CORE_PEER_MSPCONFIGPATH environment variable, where **CORE_** is the prefix for the environment variables.
