I'm following this guide https://docs.dapr.io/operations/hosting/self-hosted/self-hosted-with-docker/#run-using-docker-compose to run the scheduler, but the container is not starting, with this error in the logs:

level=fatal msg="Fatal error running scheduler: failed to create data dir: mkdir data/default-dapr-scheduler-server-0: permission denied\nfailed to serve: grpc: the server has been stopped" instance=7e97385035a1 scope=dapr.scheduler type=log ver=1.15.3

Here is what I do:

name: test
services:
    scheduler:
        command:
            - ./scheduler
            - --port
            - "50007"
        image: daprio/dapr
        ports:
            - target: 50007
              published: "50007"
        volumes:
            - type: tmpfs
              target: /data
              tmpfs:
                size: "128"

$ docker inspect 7e97385035a1 --format '{{ json .Mounts }}'
[{"Type":"tmpfs","Source":"","Destination":"/data","Mode":"","RW":true,"Propagation":""}]

Am I missing something?

Notes:

• I also tried with the daprio/scheduler container image, same error.
• Running this from GitHub Codespace: Linux codespaces-cee837 6.8.0-1021-azure #25~22.04.1-Ubuntu SMP Thu Jan 16 21:37:09 UTC 2025 x86_64 GNU/Linux
• All the other containers are running successfully: my own workloads, placement, daprd.
