# Blockchain network setup
## Copy source files
```sh
cd /home/blockchain
mkdir edunet
cd edunet
mkdir network api ui
cd network
git clone https://github.com/suddutt1/edunetbc.git . # Do not miss the .
```
## Setup the network
All the commands must be executed from network directory.
First time setup. Run the following commands
1. Download the binaries
```sh
. ./downloadbin.sh
```
2. To Generate the cryto config and other configurations
```sh
. ./generateartifacts.sh
```
3. Start the netowrk
```sh
. setenv.sh
docker-compose up -d
```
4. Build and join channel. Make sure that network is running
```sh
docker exec -it cli bash -e ./buildandjoinchannel.sh
```
5. Install and intantiate the chain codes
```sh
docker exec -it cli bash -e ./degreerecordmgmt_install.sh
```
6. Make the following /etc/hosts entries ( This will require sudo access for the blockchain user)
```sh
127.0.0.1 ca.iitj.ac.in
127.0.0.1 ca.iitkjp.ac.in
127.0.0.1 ca.edunet.net
127.0.0.1 orderer0.edunet.net
127.0.0.1 peer0.iitj.ac.in
127.0.0.1 peer0.edunet.net
127.0.0.1 peer0.iitkjp.ac.in
```
## When chain code is modified
To update the chain code , first update the chain code source files in chaincode/github.com/degreerecordmgmt directory.
Then run the following commands as appropriate
```sh
docker exec -it cli bash -e ./degreerecordmgmt_update.sh
```
## To bring up an existing network
```sh
cd /home/blockchain/edunet/network
. setenv.sh
docker-compose up -d
```
## To destory an existing network
```sh
cd /home/blockchain/edunet/network
. setenv.sh
docker-compose down
./clearVols.sh
./removeImages.sh
```
# To check the chaincode installations
```sh
. setpeer.sh EDUNET peer0
peer chaincode query -C degreerecordchannel -n degreerecordmgmt -c '{"Args":["probe"]}'
. setpeer.sh IITJ peer0
peer chaincode query -C degreerecordchannel -n degreerecordmgmt -c '{"Args":["probe"]}'
. setpeer.sh IITKJP peer0
peer chaincode query -C degreerecordchannel -n degreerecordmgmt -c '{"Args":["probe"]}'
```
