Command Line Arguments for Container in Kubernetes-CodePudding

I'm trying to deploy a docker container to my Kubernetes cluster, but I'm running into an issue with passing the required command-line arguments to the container. I need to pass two arguments called --provider local and --basedir /tmp. Here is what the docker run command looks like (I can run this without any issues on my docker host):

docker run -d -p 8080:8080 --name transfer-sh -v /tmp:/tmp dutchcoders/transfer.sh:latest --provider local --basedir /tmp

However, when I apply the deployment YAML to my cluster the container fails with this error (I'm running kubectl apply -f deploy.yaml to apply my changes to the cluster):

Incorrect Usage. flag provided but not defined: -provider local

So my YAML specifies that the flag should be --provider, but for some reason I haven't been able to find yet the container only sees -provider which is indeed not a valid option. This is the full help message:

Here is the Docker Hub for the image I'm trying to deploy: dutchcoders/transfer.sh

Here is the GitHub: https://github.com/dutchcoders/transfer.sh

My cluster's version is 1.23.4 and the full deployment YAML is here:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: transfer-sh
  namespace: transfer-sh
  labels:
    app: "transfer-sh"
spec:
  replicas: 1
  selector:
    matchLabels:
      app: transfer-sh
  template:
    metadata:
      labels:
        app: transfer-sh
    spec:
      containers:
      - name: transfer-sh
        image: dutchcoders/transfer.sh:latest
        args:
        - "--provider local"
        - "--basedir /tmp"
        ports:
        - containerPort: 8080

I intentionally have not included any persistent volume claims yet. At this point I'm just testing to make sure the container will run.

Initially, I though maybe it was some sort of escape sequence issue. After trying all manner of ways to potentially escape the two dashes nothing really changed. I also tried setting environment variables that contained those arguments, but that just resulted in the same behavior where --profile turned into -profile.

If anyone has any thoughts I could use the help. I'm a bit stuck at the moment (although still troubleshooting). I am curious if maybe there is a different way to pass in command flags as opposed to arguments (or maybe there isn't any difference as far as k8s is concerned).
