Insecure solution: COPY the secret in as a file That means any attacker getting access to the image will be able to extract your secret. Some seemingly reasonable approaches will actually result in the secret (a password, your SSH key) being embedded in the image. (Preventing leaking other kinds secrets, like runtime secrets, is covered in a different article.) Insecure options you should not use The correct solution, using modern Docker features.Some seemingly reasonable but actually insecure or problematic solutions.So how do you use build secrets in Docker without leaking them? Unlike docker run, which supports environment variables ( -e) and volumes, docker build has traditionally never had a good solution for securely using secrets. You don’t want those secrets to end up in the final image, though if it’s in the image, anyone with access to the image can extract it.
