Is it possible to pass environment variables to an already created Docker container?

Question

Docker

Do I understand correctly that environment variables cannot be transferred to a container already created on the basis of an image? I can't find the corresponding parameters in the docker start command. Unlike docker run, which, if I'm not mistaken, always creates a new container.

Answer 1

as an option - connect to the working container via docker exec additionally specifying the export command with the necessary variable.
