The invention discloses a container Dockerfile and container mirror image quick generation methods and systems. The container Dockerfile quick generation method includes the steps of for a to-be-packaged target application, running and performing tracking execution on the target application, and recording operation system dependencies of the target application in the running process; organizing and constructing a file list required for packaging the target application to a container mirror image; and according to the file list required for packaging the target application to the container mirror image, generating a Dockerfile and container mirror image file creation directory used for packaging the target application to the container mirror image. Any target application can be automatically packaged by the invention to a container; the construction of an executable minimal environmental closure of the target application is finished; the packaged container is smaller than a manually made container.
