natsio/nats-box:latest docker image contains the
nats utility this guide covers.
In one window start a JetStream enabled nats server:
$ docker run --network host -p 4222:4222 nats -js
And in another log into the utilities:
$ docker run -ti --network host natsio/nats-box
This shell has the
nats utility and all other NATS cli tools used in the rest of this guide.
Now skip to the
Administer JetStream section.
You can join a JetStream instance to your NGS account, first we need a credential for testing JetStream:
You'll want to do this outside of docker to keep the credentials that are generated.
$ nsc add user -a YourAccount --name leafnode --expiry 1M
You'll get a credential file somewhere like
~/.nkeys/creds/synadia/YourAccount/leafnode.creds, mount this file into the docker container for JetStream using
$ docker run -ti -v ~/.nkeys/creds/synadia/YourAccount/leafnode.creds:/leafnode.creds --name jetstream synadia/jsm:latest server 2020/01/20 12:44:11.752465 [INF] Starting nats-server version 2.2.0... 2020/01/20 12:55:01.849033 [INF] Connected leafnode to "connect.ngs.global"
Your JSM shell will still connect locally, other connections in your NGS account can use JetStream at this point.
