This article will explain in detail the example analysis of First Network in Hyperledger Fabric. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

First Network detailed analysis

Generate files such as fabric certificate and configuration

. / byfn.sh generate

Log analysis and manual construction of details

1. To obtain the certificate that will be generated for the network configuration defined in the crypto-config.yaml file, corresponding to the manual configuration:

.. / bin/cryptogen generate-- config=./crypto-config.yaml

Corresponding output log:

Org1.example.comorg2.example.com

The certificate and key (that is, the MSP material) are exported to the crypto-config folder in the first-network directory.

2. Where does the configtxgen tool find the configuration file configtx.yaml and call the configtxgen tool to create the orderer creation block, and configure it manually:

Export FABRIC_CFG_PATH=$PWD & &.. / bin/configtxgen-profile TwoOrgsOrdererGenesis-outputBlock. / channel-artifacts/genesis.block

The corresponding output is similar to the log:

2018-08-23 10 main 3613.825 CST [common/tools/configtxgen] main-> WARN 001 Omitting the channel ID for configtxgen is deprecated. Explicitly passing the channel ID will be required in the future, defaulting to 'testchainid'.2018-08-23 10 CST 13.825 CST [common/tools/configtxgen] main-> INFO 002 Loading configuration2018-08-23 10 testchainid'.2018 36 WARN 13.831 CST [common/tools/configtxgen/encoder] NewChannelGroup-> WARN 003 Default policy emission is deprecated, please include policy specificiations for the channel group in configtx.yaml2018-08-23 10 Swiss 3613.832 CST [common/tools/configtxgen/encoder] NewOrdererGroup-> WARN 004 Default policy emission is deprecated Please include policy specificiations for the orderer group in configtx.yaml2018-08-23 10 Loading NodeOUs2018 3613 13. 832 CST [common/tools/configtxgen/encoder] NewOrdererOrgGroup-> WARN 005 Default policy emission is deprecated, please include policy specificiations for the orderer org group OrdererOrg in configtx.yaml2018-08-23 10 common/tools/configtxgen/encoder 36 13. 832 CST [msp] getMspConfig-> INFO 006 Loading NodeOUs2018-08-23 10 Ride 36 13. 832 CST [common/tools/configtxgen/encoder] NewOrdererOrgGroup-> WARN 007 Default policy emission is deprecated Please include policy specificiations for the orderer org group Org1MSP in configtx.yaml2018-08-23 10 msp 36 CST 13.832 CST [msp] getMspConfig-> INFO 008 Loading NodeOUs2018-08-23 10 msp 36 13 832 CST [common/tools/configtxgen/encoder] NewOrdererOrgGroup-> WARN 009 Default policy emission is deprecated Please include policy specificiations for the orderer org group Org2MSP in configtx.yaml2018-08-23 10 common/tools/configtxgen 36 please include policy specificiations for the orderer org group Org2MSP in configtx.yaml2018 13.832 CST [common/tools/configtxgen] doOutputBlock-> INFO 00a Generating genesis block2018-08-23 10 common/tools/configtxgen 36 13 833 CST [common/tools/configtxgen] doOutputBlock-> INFO 00b Writing genesis block

The Genesis Block genesis.block will be exported to the channel-artifacts folder in the first-network directory.

3. Create a channel profile and configure it manually:

Export CHANNEL_NAME=mychannel & &.. / bin/configtxgen-profile TwoOrgsChannel-outputCreateChannelTx. / channel-artifacts/channel.tx-channelID $CHANNEL_NAME

The corresponding output is similar to the log:

2018-08-23 10 main 55 main [common/tools/configtxgen] main-> INFO 001 Loading configuration2018-08-23 10 main 5533.399 CST [common/tools/configtxgen] doOutputChannelCreateTx-> INFO 002 Generating new channel configtx2018-08-23 10 CST 5533.399 CST [common/tools/configtxgen/encoder] NewApplicationGroup-> WARN 003 Default policy emission is deprecated Please include policy specificiations for the application group in configtx.yaml2018-08-23 10 msp 55 msp 33.399 CST [msp] getMspConfig-> INFO 004 Loading NodeOUs2018-08-23 10 msp 55 msp 33.399 CST [common/tools/configtxgen/encoder] NewApplicationOrgGroup-> WARN 005 Default policy emission is deprecated Please include policy specificiations for the application org group Org1MSP in configtx.yaml2018-08-23 10 msp 55 msp 33.400 CST [common/tools/configtxgen] getMspConfig-> INFO 006 Loading NodeOUs2018-08-23 10 msp 5533.400 CST [common/tools/configtxgen/encoder] NewApplicationOrgGroup-> WARN 007 Default policy emission is deprecated, please include policy specificiations for the application org group Org2MSP in configtx.yaml2018-08-23 10 msp 55 please include policy specificiations for the application org group Org2MSP in configtx.yaml2018 33.401 CST [common/tools/configtxgen] doOutputChannelCreateTx-> INFO 008 Writing new channel tx

The channel configuration file channel.tx is output to the channel-artifacts folder in the first-network directory.

4. Organize the anchor node configuration file for Org1 on the constructed channel, and configure it manually:

.. / bin/configtxgen-profile TwoOrgsChannel-outputAnchorPeersUpdate. / channel-artifacts/Org1MSPanchors.tx-channelID $CHANNEL_NAME-asOrg Org1MSP

The corresponding output is similar to the log:

2018-08-23 11 CST [common/tools/configtxgen] main-> INFO 001 Loading configuration2018-08-23 11 V 07V 49.823 CST [common/tools/configtxgen] doOutputAnchorPeersUpdate-> INFO 002 Generating anchor peer update2018-08-23 11 V 07V 49.823 CST [common/tools/configtxgen] doOutputAnchorPeersUpdate-> INFO 003 Writing anchor peer update

The Org1 definition anchor peer node profile Org1MSPanchors.tx on the channel is output to the channel-artifacts folder in the first-network directory.

5. Organize the anchor node configuration file for Org2 on the constructed channel, and configure it manually:

.. / bin/configtxgen-profile TwoOrgsChannel-outputAnchorPeersUpdate. / channel-artifacts/Org2MSPanchors.tx-channelID $CHANNEL_NAME-asOrg Org2MSP

The corresponding output is similar to the log:

02.486 CST [common/tools/configtxgen] main-> INFO 001 Loading configuration2018-08-23 11 main-> INFO 0001 Loading configuration2018-08-23 11 Ride 02.493 CST [common/tools/configtxgen] doOutputAnchorPeersUpdate-> INFO 002 Generating anchor peer update2018-08-23 11 main 10 CST [common/tools/configtxgen] doOutputAnchorPeersUpdate-> INFO 003 Writing anchor peer upda

The Org2 definition anchor peer node profile Org2MSPanchors.tx on the channel is output to the channel-artifacts folder in the first-network directory.

Network startup

. / byfn.sh up

Log analysis can be divided into two parts and build details manually

The first log section

Creating network "net_byfn" with the default driverCreating volume "net_orderer.example.com" with default driverCreating volume "net_peer0.org1.example.com" with default driverCreating volume "net_peer1.org1.example.com" with default driverCreating volume "with default driverCreating volume" net_peer1.org2.example.com "with default driverCreating peer0.org2.example.com. DoneCreating orderer.example.com... DoneCreating peer1.org1.example.com... DoneCreating peer1.org2.example.com... DoneCreating peer0.org1.example.com... DoneCreating cli... Done

This part actually starts container orchestration with docker-compose. The specific commands are as follows:

Docker-compose- f docker-compose-cli.yaml up-d
