Fix error mysql not running properly

[agussetyar]

Hi, I'm trying to run this container and get that mysql is not running properly.

found the following error:

topix@2cdbed108f4b:~$ sudo tail -n 50 /var/log/mysql/error.log
2022-04-26T03:23:02.043684Z 0 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306

Then, I tried to add a little command to the Dockerfile like this:

...
RUN mkdir /var/run/sshd
RUN mkdir /var/run/mysqld
...
# mysql config
...
RUN chown mysql:mysql /var/run/mysqld
...
# volume for mysql database and install
VOLUME ["/var/lib/mysql", "/usr/share/nginx/www", "/var/run/sshd", "/var/run/mysqld"]

And everything went good.
