|
|
|
|
1. Make sure [Python 3.6+](https://www.python.org/downloads/) is installed.
|
|
|
|
|
|
2. Install [pipenv](https://github.com/kennethreitz/pipenv).
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ pip install pipenv
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
3. Create a _virtual environment_ and specify the Python version to use.
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ pipenv --python=python3.6
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
4. Install requirements.
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ pipenv install
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
5. Run the server:
|
|
|
|
|
|
* `$ pipenv run python blockchain.py`
|
|
|
|
|
|
* `$ pipenv run python blockchain.py -p 5001`
|
|
|
|
|
|
* `$ pipenv run python blockchain.py --port 5002`

## Docker
|
|
|
|
|
|
|
|
|
|
|
|
1. Clone this repository
|
|
|
|
|
|
2. Build the docker container
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ docker build -t blockchain .
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
3. Run the container
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ docker run --rm -p 80:5000 blockchain
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
4. To add more instances, vary the public port number before the colon:
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
$ docker run --rm -p 81:5000 blockchain
|
|
|
|
|
|
$ docker run --rm -p 82:5000 blockchain
|
|
|
|
|
|
$ docker run --rm -p 83:5000 blockchain
|
|
|
|
|
|
```
