Prerequites

Ensure you have the following environment variables:

• APP_OPENAI_API_KEY, create an account on OpenAI to get your API key
• APP_REPLICATE_API_TOKEN, create an account on Replicate to get your API key
• APP_ELEVENLABS_API_KEY, create an account on Elevenlabs to get your API key
• APP_GCP_PROJECT_ID, it is the ID of your project in Google Cloud Platform(https://cloud.google.com/?hl=en)
• APP_VERTEXAI_LOCATION, use a geographic location that is compatible with Vertex AI (I'm using us-central1)

Make sure to login in GCP with the command:

gcloud auth application-default login

This will allow the backend running inside the Docker container to use these credentials to authenticate with Google Cloud Services.

Use docker-compose to run the project

Ensure that you have both Docker and docker-compose installed on your system. I'm using Builtkit in the backend Dockerfile. Therefore, you must activate the corresponding environment variables to build the Docker images.

export DOCKER_BUILDKIT=1
export COMPOSE_DOCKER_CLI_BUILD=1

To start the application, simply run:

make dc-up
