Build
swift build --configuration release
Run
.build/release/Run serve
To run multiple instances, change the public port number:
.build/release/Run serve --config:server.port=8080
.build/release/Run serve --config:server.port=8081
.build/release/Run serve --config:server.port=8082
Build
$ docker build -t blockchain .
Run
$ docker run --rm -p 80:8080 blockchain
To run multiple instances, change the public port number:
$ docker run --rm -p 81:8080 blockchain
$ docker run --rm -p 82:8080 blockchain
$ docker run --rm -p 83:8080 blockchain
Thisi s just a toy blockhain implementation, do not use for production purposes, also currently blockchain is not persistent, so all data will be lost after app restart.
