NATS account configurations are built using the nsc tool. The NSC tool allows you to:

  • Create and edit Operators, Accounts, Users

  • Manage publish and subscribe permissions for Users

  • Define Service and Stream exports from an account

  • Reference Service and Streams from another account

  • Generate Activation tokens that grants access to a private service or stream

  • Generate User credential files

  • Describe Operators, Accounts, Users, and Activations

  • Push and pull account JWTs to an account JWTs server

Installation

Installing nsc is easy:

curl -L https://raw.githubusercontent.com/nats-io/nsc/master/install.py | python

Additional ways of installing nsc are described at

The script will download the latest version of nsc and install it into your system.

In case NSC is not initialized already do nsc init
