Following the tutorial does not work

[fxrobin]

Hello, I followed the tutorial (on 2 differents computer, one with WSL2, the other with native Ubuntu)
It ends up with this both times :

Here is what I've done :

$ git clone https://github.com/go-skynet/LocalAI
$ cd LocalAI
$ docker compose up -d --pull always
$ curl http://localhost:8080/models/available
$ cd models
$ curl --location 'http://localhost:8080/models/apply' --header 'Content-Type: application/json' --data-raw '{
    "id": "TheBloke/Luna-AI-Llama2-Uncensored-GGUF/luna-ai-llama2-uncensored.Q4_K_M.gguf"
}'
$  touch lunademo-chat.tmpl
$  touch lunademo-completion.tmpl
$  touch lunademo.yaml

# then editing this files as specified the tutorial 

$ curl http://localhost:8080/models/apply -H "Content-Type: application/json" -d '{
     "id": "model-gallery@lunademo"
   }'
$ curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
     "model": "lunademo",
     "messages": [{"role": "user", "content": "How are you?"}],
     "temperature": 0.9 
   }'

Any idea ?
What I'm missing ?

When you see RPC error: ... connection refused, you should always check the model name you passed to the API firstly. You can call curl http://localhost:8080/v1/models to check the available model name.
