getting-started.md

Start a lightweight Docker container

docker run --entrypoint /bin/bash -it python:3.8-slim-buster

Or can also mount local creds via a volume:

docker run --entrypoint /bin/bash -v $HOME/.nkeys/creds/synadia/NGS/:/creds -it python:3.8-slim-buster

Install nats.py and deps to install nkeys.

apt-get update && apt-get install -y build-essential curl
pip install asyncio-nats-client[nkeys]

Get the Python examples using curl

curl -o nats-pub.py -O -L https://raw.githubusercontent.com/nats-io/nats.py/master/examples/nats-pub/__main__.py
curl -o nats-sub.py -O -L https://raw.githubusercontent.com/nats-io/nats.py/master/examples/nats-sub/__main__.py
