Is it correct to rebuild a Docker image when a container is running?

Question

Docker

To speed up the deployment, I want to first rebuild the image from the Dockerfile, and then recreate and restart the container. How correct is this and will there be a failure in the running container based on this image during the build process, since the layers of the image will change in theory?

Answer 1

Absolutely normal decision. The running container will use the old image. Even if you build a new image with the same name and tag, it will still have a different id.
