Goals

Provide Fabric operators with a mechanism to build and launch chaincode outside of Docker
Begin the process of decoupling and extracting chaincode build processing from the peer

Background

Our current chaincode deployment model looks a lot like a PaaS; chaincode developers write code in the language of their choice and push it to the peer for execution. The peer, on demand, transforms the code into an executable package, launches the chaincode in an execution environment, and routes requests to the running chaincode.

Unfortunately, we have implemented this by hard coding the logic for packaging, building, and running chaincode inside Docker containers. In addition to making it difficult to experiment with new chaincode types, the implementation requires operators to grant the peer access to a Docker daemon. Since Docker daemon access enables the peer to perform a number of privileged actions, it's strongly discouraged in security conscious environments. This binding also prevents operators
