What command is used to start the Docker containers?

The command 'docker compose up -d' is used to create the containers, volumes, and start them in the background.

What is the purpose of using a Docker Compose file?

A Docker Compose file is used to define and run multi-container Docker applications, making it easier to configure and start the necessary services.

What is the role of the API key in the Flowable Artifactory?

The API key can be used instead of your password for logging in to the Flowable Artifactory, offering an additional layer of security by not storing your password directly.

What are the different Docker images available for Flowable?

The available Docker images include Flowable Work, Flowable Design, and Flowable Engage, which provide different capabilities such as process modeling and administration.

Why is a volume used for the database in the Docker Compose file?

A volume is used to store the database data persistently, ensuring that the data is not lost when the container is removed.

What is the significance of Elasticsearch in the Flowable setup?

Elasticsearch is used as the search engine within Flowable, helping to index and search process instances and other data.

How can additional custom JAR files be used with Flowable Docker images?

Additional custom JAR files can be mounted into the Docker images by specifying a directory in the Docker Compose file, allowing customization of the environment.

What is the purpose of the 'restart' policy in the Docker Compose file?

The 'restart' policy is configured to automatically restart the Flowable application if it fails to start due to missing dependencies, ensuring the service is up and running.

How do you upload a license file to Flowable Design?

After logging in to Flowable Design with the default credentials, you can upload a license file when prompted, or you can do so manually through the application interface.

What is the default port for accessing Flowable Design?

The default port for accessing Flowable Design is 8091.

How can you create a new process in Flowable Design?
