Just getting started, want to run the downloaded version of mysql:

root:~# docker images
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE

hello-world          latest              bf756fb1ae65        8 months ago        13.3kB
root:~# 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.
 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

Without re-downloading the image.

As the documentation clearly states docker run command should be invoked as follows:


so when you run

docker run mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password

Docker assumes -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password is a command you want to run inside the container, not a list of options for docker run command.

The proper docker run invocation with the parameters you specified is:

docker run -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password mysql
