Hyperledger Fabric CCaaS node.js scripts

If you are using MacOS and doesn't like to run a VM to be able to use Docker and wants to boot a Hyperleder Fabric Network, you can use these scripts.

Pre requisites

• Installed (via Homebrew preferably)
  • couchdb
  • yq
  • jq
• Hyperledger Fabric binaries (fabric-ca-server, fabric-ca-client, orderer,peer, osnadmin, configtxgen, configtxlator) on PATH. Link.
• R/W permissions on /opt/fabric
• CouchDB with an user configured. (It is expected to be admin/adminpw. if you choose to use another one, you must change peer/core.yaml @ .ledger.state.couchDBConfig.username and .ledger.state.couchDBConfig.password)

Setup:

• Clonar this repo at /opt/fabric. Just run git clone https://github.com/delaooliveira/fabric-ccaas-node-scripts.git /opt/fabric --depth 1
• Copy the contents of envs.sh.template to envs.sh and complete the envs
• Execute:
  • fabric-ca-server start from /opt/fabric/ca;
  • ./create-crypto-artefacts.sh and check for any error messages;
  • Run the other binaries:
    • couchdb
    • peer node start from /opt/fabric/peer
    • orderer start from /opt/fabric/orderer
  • ./create-channel.sh and check for any error messages;
  • ./package.sh
  • ./install-cc.sh
  • Run the chaincode as a service, either:
    • ./run-chaincode.sh or;
    • You can create a script on package.json, such as:

          "scripts": {
              "debug": "fabric-chaincode-node server --chaincode-address=localhost:7100 --chaincode-id=$(cat /opt/fabric/pkgid) --chaincode-tls-cert-file=/opt/fabric/ca/peer/tls/signcerts/cert.pem --chaincode-tls-key-file=/opt/fabric/ca/peer/tls/keystore/server.key"
          }

      and then you can attach a debugger. Neat, right?

Once the setup is complete you can boot all of the Fabric infra by running ./start.sh and can halt them all with ./stop.sh. The only exception is the Chaincode itself, you must use one of the options given on Setup.
