How to put an image inside a flex container?

Question

css

Good afternoon!
There is a flex container with a picture and a paragraph inside. I want to center everything vertically so that the image fits inside the container with respect to proportions (taking into account paddings). But for some reason it breaks out. The picture can be completely different sizes. What am I doing wrong?
Looks like this
