title: 'Separate Workers from App'

Benefits of separating workers from the main application (APP):
|
|
|
|
- **Availability**: The application remains lightweight, allowing workers to be scaled independently.
|
|
- **Security**: Workers lack direct access to Redis and the database, minimizing impact in case of a security breach.
|
|
|
|
|
|
<Steps>
|
|
<Step title="Create Worker Token">
|
|
To create a worker token, use the local CLI command to generate the JWT and sign it with your `AP_JWT_SECRET` used for the app server. Follow these steps:
|
|
1. Open your terminal and navigate to the root of the repository.
|
|
2. Run the command: `npm run workers token`.
|
|
3. When prompted, enter the JWT secret (this should be the same as the `AP_JWT_SECRET` used for the app server).
|
|
4. The generated token will be displayed in your terminal, copy it and use it in the next step.
|
|
|
|
</Step>
|
|
<Step title="Configure Environment Variables">
|
|
Define the following environment variables in the `.env` file on the worker machine:
|
|
- Set `AP_CONTAINER_TYPE` to `WORKER`
|
|
- Specify `AP_FRONTEND_URL`
|
|
- Provide `AP_WORKER_TOKEN`
|
|
</Step>
|
|
<Step title="Configure Persistent Volume">
|
|
Configure a persistent volume for the worker to cache flows and pieces. This is important as first uncached execution of pieces and flows are very slow. Having a persistent volume significantly improves execution speed.
|
|
|
|
Add the following volume mapping to your docker configuration:
|
|
```yaml
|
|
volumes:
|
|
- <your path>:/usr/src/app/cache
|
|
```
|
|
</Step>
|
|
<Step title="Launch Worker Machine">
|
|
Launch the worker machine and supply it with the generated token.
|
|
</Step>
|
|
<Step title="Verify Worker Operation">
|
|
Verify that the workers are visible in the Platform Admin Console under Infra -> Workers.
|
|
|
|
</Step>
|
|
<Step title="Configure App Container Type">
|
|
On the APP machine, set `AP_CONTAINER_TYPE` to `APP`.
|
|
