# Zeebe Worker Java Template

Minimal template for a [Zeebe](https://github.com/camunda-cloud/zeebe)

Java [worker](https://docs.camunda.io/docs/components/concepts/job-workers/). This template adds only the bare minimum

of dependencies.

If you want something more convenient, have a look

at [Spring Zeebe](https://github.com/camunda-community-hub/spring-zeebe).

## How to Use

The main method is in `Worker.java`. It requires a couple of environment variables to run.

### Connection Setup

#### Connect to Camunda Platform 8 SaaS Cluster

1. Follow the [Getting Started Guide](https://docs.camunda.io/docs/guides/getting-started/) to create an account, a

   cluster and client credentials

2. Use the client credentials to fill the following environment variables:

    * `ZEEBE_ADDRESS`: Address where your cluster can be reached.

    * `ZEEBE_CLIENT_ID` and `ZEEBE_CLIENT_SECRET`: Credentials to request a new access token.

    * `ZEEBE_AUTHORIZATION_SERVER_URL`: A new token can be requested at this address, using the credentials.

3. Run `Worker`

#### Connect to local Installation

For a local installation (without authentication) you only need to set `ZEEBE_ADDRESS`

### Workflow

Either you deploy `process.bpmn` or you design your own process with a service task with the `greet` job type.
