I searched the whole web regarding it and there is really no information about changing the default access key: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789ABCDEFGH

Endpoint=;Port=8888;AccessKey=ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789ABCDEFGH;Version=1.0

I want to change the access keys, is that possible?

This is my dockerfile:

FROM mcr.microsoft/dotnet/sdk:8.0

# Create and switch to a non-root user
RUN useradd -ms /bin/bash nonroot && \
    mkdir -p /home/nonroot/signalr && \
    chown -R nonroot:nonroot /home/nonroot

USER nonroot
WORKDIR /home/nonroot/signalr

# Install the SignalR Emulator
RUN dotnet tool install --global Microsoft.Azure.SignalR.Emulator

# Update PATH to include user's dotnet tools
ENV PATH="/home/nonroot/.dotnet/tools:${PATH}"

# Start the emulator with the custom access key
ENTRYPOINT ["asrs-emulator", "start", "-i", "0.0.0.0"]

My docker compose:

  signalr-emulator:
    container_name: signalr-emulator
    image: signalr-emulator:latest
    build:
      dockerfile: signalr/Dockerfile
    networks:
      - marble-network
    env_file:
      - .env.signalr
    volumes:
      - signalr:/home/nonroot/.aspnet
      - ./signalr/signalr-settings.json:/home/nonroot/signalr/settings.json
      - ./signalr/signalr-appsettings.json:/home/nonroot/signalr/appsettings.json
    ports:
      - "7071:7071"
      - "9999:8888"

signalr-appsettings.json

{
    "Logging": {
      "LogLevel": {
        "Default": "Information",
        "Microsoft": "Warning",
        "Microsoft.Hosting.Lifetime": "Warning"
      }
    },
    "AllowedHosts": "*",
    "AccessKey": "This key is not working but included in: .Azure.SignalR.Emulator/appsettings.json and the file is being read according to the logs when running 'asrs-emulator start -i 0.0.0.0' | I also looked at the source code of the said repo, and it seems that the Access Key is hardcoded??"
}

signalr-settings.json

{
    "UpstreamSettings": {
        "Templates": [
            {
                "UrlTemplate": ":7071/runtime/webhooks/signalr",
                "EventPattern": "*",
                "HubPattern": "*",
                "CategoryPattern": "*"
            }
        ]
    }
}

My main issue is where do i set the custom access key? Is it on an environment or a parameter in asrs-emulator? Because according to it's help command, there is no such parameter for setting the custom access key. Its fixed to this:

Endpoint=;Port=8888;AccessKey=ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789ABCDEFGH;Version=1.0
