Mysql: chown: cannot read directory '/var/lib/mysql/': Operation not permitted

[tlightsky]

in my compose file,in docker-machine(mac)

 volumes:
    - "./datadir:/var/lib/mysql"

it gives

mysql_1 | chown: cannot read directory '/var/lib/mysql/': Operation not permitted

MySQL will by default try to make itself the owner of datadir if it isn't already, which is probably denied by your system.
You could try adding the --user argument to the container to change the user the server is run as, or maybe change the permissions on ./datadir

i tried

user: ftp
user: root
user: mysql

in the docker-compose, no luck

how to change the permissions on datadir?

[sixcorners]

I did the same thing but with the socket.

volumes:
  - /var/run/mysqld:/var/run/mysqld

To get it working I had to "chown 999:0 /var/run/mysqld" on the host OS. So maybe try that with your ./datadir.

I didn't have to do this with the postgres image for some reason.

The user is resolved to the user ids in the image; have you tried a user id like user: 1000?

In my case, that was SELINUX blocking access to host shared directory. Don't disable SELINUX :bomb: , add rules instead :+1: or you can run docker as a privileged user. Details here:

Closing since this original issue is solved.

In the future, these sorts of questions/requests would be more appropriately posted to the Docker Community Forums, the Docker Community Slack, or Stack Overflow. Thanks!

        ...
        volumes:
            - ./database:/var/lib/mysql:rw
        user: mysql
        ...

• should solve the problem as it does in my case.

If others solution doesn't work, and you are on Docker Engine for MacOs.
Try to re-add the folder of your project into Files sharing. (Docker -> Settings -> Ressources ->Files sharing )
