Docker Configuration

When running this as a docker container, the XDG_CONFIG_HOME envvar is set to /config. A configuration file at /config/neon/diana.yaml is required and should look like:

MQ:
  port: <MQ Port>
  server: <MQ Hostname or IP>
  users:
    neon_llm_fastchat:
      password: <neon_fastchat user's password>
      user: neon_fastchat
LLM_FASTCHAT:
  context_depth: 3
  max_tokens: 256
  num_parallel_processes: 2
  num_threads_per_process: 4

For example, if your configuration resides in ~/.config:

export CONFIG_PATH="/home/${USER}/.config"
docker run -v ${CONFIG_PATH}:/config neon_llm_fastchat

Note: If connecting to a local MQ server, you may need to specify --network host
