Transactions examples

The examples' folder contains examples for basic transactions, here we describe how to build and run examples inside docker.

Prerequisites

To build a docker image, the following are the prerequisites that should be installed.

  • Docker: To run the BCDB image.
  • Git: To clone the code repository.

Build

To clone the repository, create the required directory

mkdir -p github.com/hyperledger-labs

Change the current working directory to the above created folder

cd github.com/hyperledger-labs

Clone server and sdk repositories

git clone https://github.com/hyperledger-labs/orion-server

git clone https://github.com/hyperledger-labs/orion-sdk-go

Change the current working directory to the server root directory

cd orion-server

View orion-sdk-go/go.mod and copy the server 

cat ../orion-sdk-go/go.mod

Switch to the right version of the server that runs with the sdk

git checkout <commit-hash>

Generate cryptographic materials

Generate crypto materials for users used in the examples

./scripts/cryptoGen.sh sampleconfig alice bob charlie

For more options about crypto generation, see here

Generate docker image

make docker

Start the server inside a docker container

docker run -it --rm -v $(pwd)/deployment/crypto/:/etc/orion-server/crypto -p 6001:6001 \
    -p 7050:7050 orionbcdb/orion-server

Docker image contains already all required configuration files, so thise command is enough for basic run.

For information how to customize docker run parameters, including Orions server configuration, see here

After this step, you can run multiple examples one after another without repeating the build process

Run an example

Go to the example directory

cd ../orion-sdk-go/examples/api/<example-dir>

Build and run

go build

./<example-dir>

Clean up

Delete directories after running the examples

cd ../../../../orion-server/sampleconfig

rm -r txs ledger
