Running MySQL in Docker and persisting data to my created directory [duplicate]

Question

I'm trying to run MySQL in Docker and persist the data to a directory I created.

docker run --name mysql-mac -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my_strong_password -d mysql:latest -v /Users/alexeyzhulin/Projects/data /mysql:/var/lib/mysql

Containers are started and stopped. In the container log I can see:

When I run the container without persisting data to the directory I created, it works fine.

docker run --name mysql-mac -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my_strong_password -d mysql:latest

How do I run MySQL in Docker and persist the data to a directory I create?

Answer 1

Make sure that the directory you create is owned by the mysql user
