Hello,
I am trying to connect to weaviate using loca_instance below is my code snippet:

self.client = weaviate.connect_to_local(
                host="0.0.0.0",  # Use a string to specify the host
                port=8080,
                grpc_port=50051,
                headers=headers,
                auth_credentials=AuthApiKey(weaviate_api_key)
            )

I am running it using docker, my docker compose is as below:

eaviate:
    command:
      - --host
      - 0.0.0.0
      - --port
      - '8080'
      - --scheme
      - http
    image: cr.weaviate.io/semitechnologies/weaviate:1.27.8
    ports:
      - 8080:8080
      - 50051:50051
    volumes:
      - weaviate_data:/var/lib/weaviate
    restart: on-failure:0
    env_file: .env
    healthcheck:
      test: wget --no-verbose --tries=3 --spider http://localhost:8080/v1/.well-known/ready || exit 1
      interval: 5s
      timeout: 10s
      retries: 5
      start_period: 10s

I am getting below error for connecting to weaviate

Hey @Rohini_vaidya,

As we discussed during the community office hour, please make sure to configure your Docker Compose with like this at the top of your conatiners:

networks:
  example_network:
    driver: bridge

Then, in each container configuration, add:

networks:
  - example_network

After that, re-run your containers for the API app and any other services you’re using — everything should work fine.

Let me know if that solves the issue
