Lab7: join peers from org2 to channel
After starting containers of peer0 and peer1 from org2 they should join the channel: "allarewelcome"
This is supposed to happen through the CLI container.
peer channel fetch config Org2AddedConfig.pb \
-o orderer.example.com:7050 -c allarewelcome
After fetching the cfg:
peer channel join -b allarewelcome.block
but this does not work, because there is no allarewelcome.block in the cli container.
I then joined them by going into bash from peer0 and peer1 and type:
peer channel fetch oldest allarewelcome.block -c allarewelcome \ --orderer orderer.example.com:7050
peer channel join -b allarewelcome.block
Is this wrong? What does the "fetch config" supposed to do?
thx in advance.

Hi @atpc , seems like there is a small typo in the PDF document, as the correct command should be "peer channel join -b Org2AddedConfig.block" from the CLI.
Well done finding a way around anyway!
Here is some more information for you regarding the fetch command, from the official documentation (https://hyperledger-fabric.readthedocs.io/en/release-1.4/commands/peerchannel.html)
