Problems with setting read_only:true

[hieuhgt]

My AWS Security Hub was failed with ECS containers must restrict access to the root file system to read-only so i want to add read_only to my Docker compose file but it make the container can not build! I have many problem with s6
Here is my docker-compose.yaml

  https-portal:
    read_only: true
    image: steveltn/https-portal:1
    ports:
      - '8081:443'
    environment:
      DOMAINS: 'localhost -> http://host.docker.internal:8080'
      STAGE: local
    volumes:
      - s6-overlay:/var/run/s6:rw

And the error =>

When i set the volume to s6-overlay:/var/run/s6/etc:rw, it lead to another problems

backend-https-portal-1  | s6-rmrf: fatal: unable to remove /var/run/s6/container_environment: Read-only file system

I am newbie with docker so I'm having quite a bit of difficulty with this part. Thank you for supporting me
