I got [Errno 13] Permission denied: './docker-compose.yml' running docker

I installed docker on kubuntu 18 , but I got error

$ docker-compose up -d --build
ERROR: .PermissionError: [Errno 13] Permission denied: './docker-compose.yml'

Reading branch https://stackoverflow.com/questions/60025430/docker-error-ioerror-errno-13-permission-denied-docker-compose-yml I tried to salve it :

username@ubuntuOS:/ProjectPath/DOCKER$ sudo groupadd docker
[sudo] password for username:
groupadd: group 'docker' already exists
username@ubuntuOS:/ProjectPath/DOCKER$ sudo gpasswd -a $USER docker
Adding user username to group docker
username@ubuntuOS:/ProjectPath/DOCKER$ docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
