My image base is Ubuntu 16, the problem is when i execute /usr/bin/mysqld_safe --user=mysql --skip-grant-tables my terminal stays in black and i can´t type or do anithing inside. Is there a way to execute this command and send the proceess to background? this container needs to execute commands and at the same time runing mysql in background.

Manual

Start docker container daemonized
docker run -d --name mysql <image> -- /usr/bin/mysqld_safe --user=mysql --skip-grant-tables

Connect to container and run commands:
docker exec -it mysql sh

Entrypoint

Common approach is to use an entrypoint script.

#!/bin/sh
# entrypoint.sh

/usr/bin/mysqld_safe --user=mysql --skip-grant-tables &
# more commands etc.

set script as executable

chmod 755 entrypoint.sh

Then in your Dockerfile:
ADD entrypoint.sh .
ENTRYPOINT ["./entrypoint.sh"]
