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

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

How can it be fixed ?

Thanks!

You might want to turn off apparmor and check if it works without. If this is the case, you will need to figure out how to permit access for the file - I never had to tinker around with apparmor on Ubuntu.

sudo systemctl stop apparmor
#run your test, then restart apparmor again
sudo systemctl start apparmor

By any chance are you running the Docker package from Snap?

Stopping apparmor I got errors:

username@ubuntuOS:ProjectPath$ sudo systemctl stop apparmor
[sudo] password for serge:
username@ubuntuOS:ProjectPath$ sudo systemctl enable docker
Synchronizing state of docker.service with SysV service script with /lib/systemd/systemd-sysv-install.

username@ubuntuOS:ProjectPath$ sudo systemctl start docker
Failed to start docker.service: Unit docker.service is masked.
username@ubuntuOS:ProjectPath$ sudo systemctl start apparmor

I installed docker with command :

sudo apt-get install docker-ce

Is it snap installation?

docker info

 Context:    default

 Plugins:
  app: Docker App (Docker Inc., v0.9.1-beta3)
  buildx: Build with BuildKit (Docker Inc., v0.5.1-docker)

Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info

In which way have I to check is it snap installation and how my errors depends on it ?

I failed to run docker :

$ sudo systemctl enable docker
[sudo] password for serge:

$ sudo systemctl start docker

In my Synaptic I found installed packages:

snap
location of genes from DNA sequence with hidden markov model

and

apparmor
user-space parser utility for AppArmor

I have some prior docker expierence, but I did not have such problems.
How these can be fixed?
