Local client connection with localhost:8080 failed

Support
1

Hi All,

I am new to weaviate and try to do RAG with langchain and using Huggingface embeddings.
I have downloaded the yaml file and got it running in a docker container.
I am using windows10 and have wsl installed. I can see that localhost:8080/v1 displaying the links.
I have a windows conda environment py10.

import weaviate
client = weaviate.Client(‘http://weaviate:8080’)
print(‘after client connection’)
then i get the following error… I do NOT see the print statement.
What I am doing wrong?

error

Hi @htbit1990 !! Welcome to our community :hugs:

If both Weaviate and your App are running from the same docker-compose file, they should reference each other by it’s service name.

In that scenario,

import weaviate
client = weaviate.Client("http://weaviate:8080")
client.is_ready()

should work

However, if you are running Weaviate inside a container, and you app is running locally (which I believe is your scenario), like a script you are executing, you will need to point to

client = weaviate.Client("http://weaviate:8080")

Let me know if that helps!

Thanks!

I’ve just installed Weaviate using pip (so, its up to date) and try to connect locally using your code above. I get the errors:

raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPConnectionPool(host='weaviate', port=8080): Max retries exceeded with url: /v1/.well-known/openid-configuration (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x0000015DD90683D0>: Failed to resolve 'weaviate' ([Errno 11001] getaddrinfo failed)")).

Well,. its my first experientce with Weaviate. I also got deprecation warning, so I have installed update of the client to v4. but I just installed Weaviate. I am so confused.

hi @Jacck ! Welcome to our community :hugs:

We need more information to be able to help you here.

1 - How are you running Weaviate? Locally? Using our WCS?
2 - Can you share the code you are using?

Thanks!

I would like to try DSPy with Weaviate. Just simple set up. I use latest version of Weaviate on my laptop: 4.5.4. I get DeprecationWarning: Dep016: You are using the Weaviate v3 client, which is deprecated.
Consider upgrading to the new and improved v4 client instead!
See here for usage: Python | Weaviate - Vector Database and errors. I do not get it what should I do just to make simple use case. After line: client = weaviate.Client(“http://weaviate:8080”), i got raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPConnectionPool(host=‘weaviate’, port=8080): Max retries exceeded with url: /v1/.well-known/openid-configuration (Caused by NameResolutionError(“<urllib3.connection.HTTPConnection object at 0x000001C56ED996C0>: Failed to resolve ‘weaviate’ ([Errno 11001] getaddrinfo failed)”))
