Mount volumes for mysql container

Question

I can initiate a docker container using a command like this...

[root@localhost ~]# sudo docker run -p 3396:3306  -d mysql:5.7

But when I mount a volume, it does not work. I get permission denied error as shown below.

[root@localhost ~]# sudo docker run -p 3397:3306 -v /tmp/mysql/:/var/lib/mysql -d mysql:5.7

chown: cannot read directory '/var/lib/mysql/': Permission denied

How do I mount volumes? I am facing this problem of this server only. On the other servers, the above command works correctly.

I tried with -u option, but get a different error this time...

[root@localhost ~]# sudo docker run -p 3397:3306  -u 1000:50   -v /tmp/mysql/datadir3396d:/var/lib/mysql -d mysql:5.7

Answer 1

Execute

rm -rf /tmp/mysql

Then run below

sudo docker run -e MYSQL_ROOT_PASSWORD=root -p 3397:3306 -v /tmp/mysql/:/var/lib/mysql -d mysql:5.7

You need to provide the MYSQL_ROOT_PASSWORD environment variable with root password for it to work
