Docker volume mount is empty, when attempting to create volume

Im pretty new to docker, i've set up a few containers on my raspberry pi - They are running a website and i'd like to save user images. If i read correctly i need to mount a directory in my docker container "/world" to a volume i create.

I created the volume: docker volume create images_test

I attempted to link it using docker run:

docker run -it --privileged=true -d --network nginxnetwork --name=schedule-events-backend berthelmaster0802/schedule-events-backend -v images_test:/world uname -m armv7l;

My Dockerfile:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app


COPY *.csproj ./
RUN dotnet restore


COPY . ./
RUN dotnet publish -c Release -o out


FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "backend.dll"]

When i inspect my container:

docker inspect schedule-events-backend
        "Mounts": [],
        "Config": {
            "Hostname": "8044b26c4ed7",
            "Domainname": "",
            "User": "",
            "AttachStdin": false,
            "AttachStdout": false,
            "AttachStderr": false,
            "Tty": true,
            "OpenStdin": true,
            "StdinOnce": false,
            "Env": [
                "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
                "ASPNETCORE_URLS=http://+:80",
                "DOTNET_RUNNING_IN_CONTAINER=true"
            ],

My mount seems to be empty still. Anyone can figure out what im doing wrong?

@DavidMaze solved the problem, thank you so much: "You've added the -v option after the image name, so it will be interpreted as the command to run and not a Docker option (you should see this in the docker inspect output too). Move the option before the image name"
