Building

NSC uses go modules. If your project source is in $GOPATH, you must define set the environment variable GO111MODULE to on.

Running with Docker

The NATS team maintains a lightweight Docker image with many of the NATS utilities called nats-box where nsc is included. You can mount a local volume to get nsc accounts, nkeys, and other config back on the host using Docker as follows:

docker run --rm -it -v $(pwd)/nsc:/nsc natsio/nats-box:latest

# In case NSC not initialized already:
nats-box:~# nsc init
nats-box:~# chown -R 1000:1000 /nsc
$ tree -L 2 nsc/
