This is a repackaged open source software product wherein additional charges apply for cloudimg support services.
Overview NATS is an open source high performance messaging system from Synadia, used as the connective tissue for cloud native and edge applications. This image delivers NATS Server fully installed and configured, so a complete messaging platform is running within minutes of launch.
What Is Included The NATS Server binary from the official upstream GitHub release, installed under /usr/local/bin. A systemd unit (nats-server.service) that runs the server as a dedicated nats system user. JetStream, the NATS persistence layer, enabled by default with its store directory on a dedicated data volume. A baseline server configuration with a single authenticated user, client port 4222 and the HTTP monitoring endpoint on port 8222.
Dedicated Storage Tier The JetStream store directory and any NATS data files live on a separate, independently resizable storage volume mounted at /var/lib/nats. The messaging persistence tier is kept off the operating system disk so it can be grown to accommodate larger streams and key value buckets without disturbing the rest of the instance.
Per Instance Credentials On First Boot On the first boot of your instance a one shot service generates a 32 character random password for the cloudimg NATS user, writes it to /root/nats-credentials.txt with file mode 0600, and configures it as the single authenticated user in /etc/nats/auth.conf. Every instance gets its own credentials, so the password is never baked into the image.
Headless, No Web UI NATS runs headless. There is no built in web console; status and metrics are exposed by the monitoring HTTP endpoints on port 8222 (/varz for server stats, /connz for clients, /healthz for liveness, /jsz for JetStream state). Third party tools such as NATS Surveyor can attach if a UI is required.
Ready To Use The NATS Server is enabled and starts automatically at boot. The client port 4222 and monitoring port 8222 are bound to localhost in the captured image. Open the firewall and edit /etc/nats/nats-server.conf to expose them to your network.

Usage instructions
Connect via SSH on port 22 as the default login user for your operating system variant (the user guide lists it per variant). The NATS Server is already running under systemd as nats-server.service. Read the rotated cloudimg user password from /root/nats-credentials.txt (sudo cat /root/nats-credentials.txt). The client port 4222 and monitoring port 8222 are bound to 127.0.0.1 in the captured image; edit /etc/nats/nats-server.conf to set 'host: 0.0.0.0' and open the corresponding security group rules to expose NATS to your network. Confirm liveness with: curl http://127.0.0.1:8222/healthz .
