# Getting started with Python and NGS running in Docker
|
|
|
|
Start a lightweight Docker container:
|
|
|
|
```
|
|
docker run --entrypoint /bin/bash -it python:3.8-slim-buster
|
|
```
|
|
|
|
Or you 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 dependencies 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
|
|
```
|
|
|
|
Create a subscription that lingers:
|
|
|
|
```
|
|
python nats-sub.py --creds /creds/NGS.creds -s tls://connect.ngs.global:4222 hello &
|
|
```
|
|
|
|
Publish a message:
|
|
|
|
```
|
|
python nats-pub.py --creds /creds/NGS.creds -s tls://connect.ngs.global:4222 hello -d world
|
|
```
