From host to container:
docker cp ./local/file.txt container:/app/
It's cruel to use the word container in a "cheatsheet" when it's actually a placeholder. Using ${container_id_or_name}:/app would make it more obvious and would actually error out if the user attempts to copy-paste
In the spirit of being helpful, this is also good fun (but I think it does require a copy of /bin/tar in the image):
tar -cf - my-dir my/file.txt | docker cp - ${container_id}:/my/dest/
---
the "-e" also has two different syntaxes, depending on if one needs to rename the variable as it goes into the container:
export AWS_ACCESS_KEY_ID
docker run -e AWS_ACCESS_KEY_ID my.image
# versus
docker run -e AWS_KEY=$AWS_ACCESS_KEY_ID my.image
I kinda wish that it was an actual printable cheatsheet and not just a list of commands on a website that I have to bookmark and hope it's still up in a year.

The docker-compose syntax ist valid for compose/v1 which was last updated in 2021. yet this article is from 2025. is vibe-docing now a thing also?
Hey! Thanks for pointing it out. I just double-checked the article, and actually — nothing there is outdated
