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


Installing nsc is easy:
curl -L | python
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
Output of tree -L 2 nsc/
