I've been experimenting with Hyperledger Fabric, deployed over 2 VirtualBox Ubuntu images with docker swarm. But I have some issues when it comes to the Composer installation.
Network Setup:
Host1: Orderer, Peer1.Org1, Peer2.Org1, CLI
Host2: Peer1.Org2, Peer2.Org2
When it comes to the Fabric setup everything appears to be ok. I'm able to start the network, join the peers from the second host, and update the anchor peers (one for each organisation).
The Composer installation starts with creating and importing the business network card and then installing the .bna file onto the network.
The issues appear when I try to start the network:
Error: Error trying to start business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: failed to execute transaction 14f90ad938da64fbbdb2923b07f4985251391937fc3fdc8bab19c2d13135ecd3: error starting container: error starting container: API error (500): Could not attach to network net_example: rpc error: code = NotFound desc = network net_example not found Response from attempted peer comms was an error: Error: failed to execute transaction 14f90ad938da64fbbdb2923b07f4985251391937fc3fdc8bab19c2d13135ecd3: error starting container: error starting container: API error (500): Could not attach to network net_example: rpc error: code = NotFound desc = network net_example not found Response from attempted peer comms was an error: Error: Failed to connect before the deadline Response from attempted peer comms was an error: Error: Failed to connect before the deadline When I inspect the first peer from org1, I'm seeing the following error:
