How to find out the weight of a docker container (running and not, so is image)?

Question

Docker

For example with golang. I'll write the code myself, tell me which command shows the weight of the container or image (it doesn't matter in bytes or megabytes)? Or do you just need to go into the folder and count the files?

Answer 1

docker imagesshows the size of the image
docker ps -sor docker ps -asprints the size of the container
