Install NATS

info

Installation prerequisites

  • Docker - If you decide to run NBomber Cluster, installing Docker and Docker Compose is required.

To run NBomber Cluster, you need to install NATS message broker. The simple way is to use Docker for this.

info

Please, use NATS version 2.9.9. NATS should be configured to use JetStream. In the docker-compose.yaml file, we enable JetStream on startup via command: --js. Also, a single-node NATS server is enough to run multiple NBomber Clusters in parallel.

docker-compose.yaml
version: "3.4"
services:

    nats:
        image: "nats:2.9.9"
        command: --js
        ports:
            - "8222:8222"
            - "4222:4222"

Open the folder where the docker-compose.yaml file is located.

Start container.

docker compose up -d

Stop container.

docker compose down
