In modern development, the mainstream approach to software configuration management, such as managing external dependencies and resolving dependencies, is to use package management tools. However, these tools often do not record detailed configuration information for external dependencies, making it difficult to detect and identify issues caused by faults unrelated to changes in the source code.
We proposes Continuous Dockerfile Configuration Management (CDCM) as a configuration management process that achieves both configurational reproducibility and buildability in Dockerfile. CDCM consists of the continuous operation of Moldfile, which rigorously records external dependency configurations, and the estimation generation of Moldfile at past points in time.
