How can I use the discover tool in Hyperledger Fabric 1.2 with CLI? I have the 1.2 binary and fabric files. I tried to execute discover command in the cli container in first-network, but I received an error saying "command not found"
You can build it locally via cloning the repository and running make discover, or download the binaries from nexus. In the next releases it will be part of the fabric-tools image.
