When using an environment variable to set the proxy secrets, the value should be a comma-separated list of strings, such as `secret-one,secret-two`.

### Running the proxy via Docker
The easiest way to run Unleash is via Docker. We have published a [docker image on docker hub](https://hub.docker.com/r/unleashorg/unleash-proxy).
**Step 1: Pull**
1. **Pull the Proxy image**
```bash
docker pull unleashorg/unleash-proxy
```
**Step 2: Start**
2. **Start the proxy**

**Step 3: verify**
### Running the proxy using Node.js
In order to verify the proxy you can use curl and see that you get a few evaluated feature toggles back:
To run the Proxy via Node.js, you'll have to create your own Node.js project and use the Unleash Proxy as a dependency. Assuming you've already set up your project, here's the steps to take to start the proxy as part of your app:
1. **Install the Unleash Proxy package**
``` shell npm2yarn
npm install @unleash/proxy
```
2. **Initialize and start the proxy in your code.** A fully working sample app that uses the proxy:
``` js
const port = 3000;
const { createApp } = require('@unleash/proxy');
const app = createApp({
unleashUrl: 'https://app.unleash-hosted.com/demo/api/',
unleashApiToken: '56907a2fa53c1d16101d509a10b78e36190b0f918d9f122d',
clientKeys: ['some-secret', 'another-proxy-secret', 's1'],
refreshInterval: 1000,
});
app.listen(port, () =>
console.log(`Unleash Proxy listening on http://localhost:${port}/proxy`),
);
```
### Verify that the proxy is working
In order to verify the proxy you can use curl and see that you get a few evaluated feature toggles back. Assuming that the proxy is running at port 3000 and that your proxy client key is `some-secret`, you could run this command :
```bash
curl http://localhost:3000/proxy -H "Authorization: some-secret"

The output is of the form described in the [payload section](#payload).
**Health endpoint**
### Health endpoint
The proxy will try to synchronize with the Unleash API at startup, until it has successfully done that the proxy will return `HTTP 503 - Not Read?` for all request. You can use the health endpoint to validate that the proxy is ready to recieve requests:
