# 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 addons. This is important as first uncached execution of addons and flows are very slow. Having a persistent volume significantly improves execution speed.

    Add the following volume mapping to your docker configuration:

    ```yaml theme={null}
    volumes:
      - <your path>:/usr/src/app/cache
    ```

    Note: This setup works whether you attach one volume per worker, It cannot be shared across multiple workers.
  </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`.
  </Step>
