# Setup NATS
|
|
|
|
## Locally
|
|
|
|
You can run a NATS server locally using Docker:
|
|
|
|
```bash
|
|
docker run -d --name nats-main -p 4222:4222 -p 6222:6222 -p 8222:8222 nats
|
|
```
|
|
|
|
You can then interact with the server using the client port: `localhost:4222`.
|
|
|
|
## Kubernetes
|
|
|
|
The easiest way to install NATS on Kubernetes is by using the [Helm chart](https://github.com/helm/charts/tree/master/stable/nats):
|
|
|
|
```bash
|
|
helm install nats stable/nats
|
|
```
|
|
|
|
This will install NATS into the `default` namespace.
|
|
To interact with NATS, find the service with: `kubectl get svc nats-client`.
|
|
|
|
For example, if installing using the example above, the NATS server client address would be:
|
|
|
|
`nats-client.default.svc.cluster.local:4222`
|
|
|
|
## Create a Dapr component
|
|
|
|
The next step is to create a Dapr component for NATS.
|
|
|
|
Create the following YAML file named `nats.yaml`:
|
|
|
|
```yml
|
|
apiVersion: dapr.io/v1alpha1
|
|
kind: Component
|
|
metadata:
|
|
name: <name>
|
|
spec:
|
|
type: pubsub.nats
|
|
metadata:
|
|
- name: natsURL
|
|
value: <REPLACE-WITH-NATS-SERVER-ADDRESS> # Required. Example: "nats-client.default.svc.cluster.local:4222"
|
|
```
|
|
|
|
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here](../../concepts/secrets/README.md)
|
|
|
|
## Apply the configuration
|
|
|
|
### In Kubernetes
|
|
|
|
To apply the NATS pub/sub to Kubernetes, use the `kubectl` CLI:
|
|
|
|
```bash
|
|
kubectl apply -f nats.yaml
|
|
```
|
|
|
|
### Running locally
|
|
|
|
The Dapr CLI will automatically create a directory named `components` in your current working directory with a Redis component.
|
|
To use NATS, replace the contents of `messagebus.yaml` file with the contents of `nats.yaml` above (Don't change the filename).
