Labs Ch 8 Answers

The following post was meant for the LFS272 forum. Not sure how I got into the wrong area.

This is not at all true for the final statement in Lab 8:

If you were initializing a chainode that implements the Fabric contract API (instead of the Fabric
Chaincode Shim API), then you’d need to specify the name of the initialization function to be
called in the chanincode. For example:
peer chaincode invoke -o orderer.example.com:7050 --tls --cafile
$ORDERER_TLS_CA -C allarewelcome -n mychaincode --peerAddresses
$CORE_PEER_ADDRESS --tlsRootCertFiles $CORE_PEER_TLS_ROOTCERT_FILE -c
'{"function":"initLedger","args":["key0", "value0"]}' --isInit
--waitForEvent
We leave as an exercise to the reader to upgrade the sacc chaincode one more time, this time specifying that it must be initialized as described above.

I have seen nothing in the course materials that addresses how to do this. There are not helpful references back to specific locations in the hyperledger fabric 2 docs either.

Also there is no code to verify this. It is the final statement in the lab.

How am I supposed to use this material to prepare for an exam if topics are not explained properly?
