If you’re using [Porter Cloud](https://cloud.porter.run/) to manage your deployments, you can easily integrate with Subtrace to monitor your app’s network requests. Depending on how you build your app on Porter, the instructions are different. We’ll use a Next.js app as an example, but you can do this with any language and framework.

### Dockerfile

Make the following changes to your app’s Dockerfile:

```
- CMD ["npm", "run", "start"]
+ RUN curl -fsSLO "https://subtrace.dev/download/latest/$(uname -s)/$(uname -m)/subtrace" && chmod +x ./subtrace
+ CMD ["./subtrace", "run", "--", "npm", "run", "start"]
```

Get a `SUBTRACE_TOKEN` from the **Tokens** page on the [dashboard](/content/dashboard/index.html) and set it as an environment secret on Porter:

Click the lock icon on the right to make it a secret.

And then deploy your app as you normally would. That’s it! You can now visit your app and make some requests to see them automatically appear in the Subtrace dashboard.

If you’re using Buildpacks, the easiest way to integrate Subtrace would be to just change the command that’s used to start your app on Porter. Create a file called `start.sh` in your repo root that downloads Subtrace and starts your app:

```
#!/usr/bin/env bash
curl -fSLO "https://subtrace.dev/download/$(uname -s)/$(uname -m)/subtrace" && chmod +x ./subtrace
./subtrace run -- npm run start # replace with your app command
```

Change your app’s start command on Porter to run this script:

Get a `SUBTRACE_TOKEN` from the **Tokens** page on the [dashboard](/content/dashboard/index.html) and set it as an environment secret on Porter:

Click the lock icon on the right to make it a secret.
