### Re-Configuration
### Re-Configuration example
Refer to [create a new ordering system channel](http://hyperledger-fabric.readthedocs.io/en/latest/configtxlator.html#reconfiguration-example)
1. here we will introduce how to re-configuration config.block, first fetch the block and translate it to json.
### [WIP]/configtxlator/compute/update-from-configs
```bash
$ ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
$ peer channel fetch config -o orderer.example.com:7050 -c businesschannel --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA|xargs mv true config_block.pb
### [WIP]/configtxlator/config/verify
$ peer channel fetch config config_block.pb -o orderer.example.com:7050 -c businesschannel # with no-tls
$ curl -X POST --data-binary @config_block.pb http://127.0.0.1:7059/protolator/decode/common.Block > config_block.json
```
2. Extract the config section from the block:
```bash
$ apt-get install jq
$ jq .data.data[0].payload.data.config config_block.json > config.json
```
3. edit the config.json, set the batch size to 11, and saving it as update_config.json
```bash
4. $ jq ".channel_group.groups.Orderer.values.BatchSize.value.max_message_count = 11" config.json > updated_config.json
```
5. Re-encode both the original config, and the updated config into proto:
```bash
$ curl -X POST --data-binary @config.json http://127.0.0.1:7059/protolator/encode/common.Config > config.pb
$ curl -X POST --data-binary @updated_config.json http://127.0.0.1:7059/protolator/encode/common.Config > updated_config.pb
```
6. send them to the configtxlator service to compute the config update which transitions between the two.
```bash
$ curl -X POST -F original=@config.pb -F updated=@updated_config.pb http://127.0.0.1:7059/configtxlator/compute/update-from-configs -F channel=businesschannel > config_update.pb
```
7. we decode the ConfigUpdate so that we may work with it as text:
```bash
$ curl -X POST --data-binary @config_update.pb http://127.0.0.1:7059/protolator/decode/common.ConfigUpdate > config_update.json
```
8. Then, we wrap it in an envelope message:
```bash
$ echo '{"payload":{"header":{"channel_header":{"channel_id":"businesschannel", "type":2}},"data":{"config_update":'$(cat config_update.json)'}}}' > config_update_as_envelope.json
```
9. Next, convert it back into the proto form of a full fledged config transaction:
```bash
$ curl -X POST --data-binary @config_update_as_envelope.json http://127.0.0.1:7059/protolator/encode/common.Envelope > config_update_as_envelope.pb
````
10. Finally, submit the config update transaction to ordering to perform a config update.
```bash
$ CORE_PEER_LOCALMSPID=OrdererMSP
$ CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/users/Admin@example.com/msp
$ peer channel update -o orderer.example.com:7050 -c businesschannel -f config_update_as_envelope.pb --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA
$ peer channel update -f config_update_as_envelope.pb -o orderer.example.com:7050 -c businesschannel # with no-tls
```
### [WIP]Add an organization
1. Execute `configtxgen` to generate `channel.tx`
```bash
$ ORDERER_GENERAL_GENESISPROFILE=SampleDevModSolo #Change this env before start ordering service.
```
```bash
$ docker exec -it fabric-cli bash
$ configtxgen -profile SampleDevModSolo -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID businesschannel
```
2. create channel use channel.tx, then we will get block businesschannel.block
```bash
$ peer channel create -o orderer.example.com:7050 -c businesschannel -f ./channel-artifacts/channel.tx
```
3. Start configtxlator
```bash
$ docker exec -it fabric-cli bash
$ configtxlator start
```
4. In a new window, decoding current genesis block
```bash
$ curl -X POST --data-binary @businesschannel.block http://127.0.0.1:7059/protolator/decode/common.Block > businesschannel.json
```
5. Extract current config
```bash
jq .data.data[0].payload.data.config businesschannel.json > config.json
```
6. generating new config
```bash
jq '. * {"channel_group":{"groups":{"Application":{"groups":{"ExampleOrg": .channel_group.groups.Application.groups.SampleOrg}}}}}' config.json |
jq '.channel_group.groups.Application.groups.ExampleOrg.values.MSP.value.config.name = "ExampleOrg"' > update_config.json
```
7. Translate config.json and update_config.json to proto
```bash
curl -X POST --data-binary @config.json http://127.0.0.1:7059/protolator/encode/common.Config > config.pb
curl -X POST --data-binary @update_config.json http://127.0.0.1:7059/protolator/encode/common.Config > update_config.pb
```
8. Computing config update
```bash
curl -X POST -F original=@config.pb -F updated=@update_config.pb http://127.0.0.1:7059/configtxlator/compute/update-from-configs -F channel=businesschannel > config_update.pb
```
9. Decoding config update
```bash
curl -X POST --data-binary @config_update.pb http://127.0.0.1:7059/protolator/decode/common.ConfigUpdate > config_update.json
```
10. Generating config update envelope
```bash
echo '{"payload":{"header":{"channel_header":{"channel_id":"businesschannel", "type":2}},"data":{"config_update":'$(cat config_update.json)'}}}' > config_update_in_envelope.json
```
11. Next, convert it back into the proto form of a full fledged config transaction:
```bash
curl -X POST --data-binary @config_update_in_envelope.json http://127.0.0.1:7059/protolator/encode/common.Envelope > config_update_in_envelope.pb
```
12. Sending config update to channel
```bash
$ CORE_PEER_LOCALMSPID=OrdererMSP
$ CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/users/Admin@example.com/msp
$ peer channel update -o orderer.example.com:7050 -c businesschannel -f config_update_in_envelope.pb --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA
$ (optional)peer channel update -f config_update_as_envelope.pb -o orderer.example.com:7050 -c businesschannel # with no-tls
```

When you set *TLS_ENABLED=true, then you can fetch blocks using following command:
