Digital Ocean droplet size

Hi,
I have a relative small NodeJS app with mySQL database.
(Database is almost empty)
I tried to deploy my app to DO this morning and got a message that the droplet was full. The basic droplet is 25GB. Looking at the graphs in the Docker dashboard I can see that the disk space is at 100%.
Does it eat so much disk space so quickly with a simple app with a NodeJS server and MySQL server?

In the meantime I doubled the space to 50GB, let’s see how it goes.
