this is my compose file for monbooru, ive added some comments to show you what each thing does, if you want to change the port simply change the the first 8080. all of these value:value mean that the first value is your machine, and the second one inside the container. that's it, create a folder named monbooru, create a file named docker-compose.yml, add the thing i gave you below and save it. with your terminal cd into the directory where the compose file lives and do docker compose up -d and it will download the image and it'll be runnin. believe me, i used to prefer to not use docker because i thought, ohh i have to learn to use docker, but honestly i wish i knew it was this simple long before so i wouldnt have done so many installs of some apps where i'll lose my data
