Backend & APIs/Uploads & mediaQuestion

What checks belong in a secure image-upload endpoint?

I am adding screenshots to community posts. The browser provides a MIME type, but I know that value can be forged. Current checks 4 MB maximum PNG, JPEG, WebP, or GIF Random generated filename What should happen before the file reaches object storage?

Tools & deployment/Docker & deploymentQuestion

Docker environment variable exists during build but disappears at runtime

The image builds successfully and prints the variable in one build step, but the Node process sees undefined after deployment. Code example I am currently considering copying the value into the image with ENV . Is that safe for a server secret?
