Hi, for development and testing (integration testing) I want to have a Docker image with a pre-filled Postgres database. It should be a simple and quick task to spin-up this database, e.g., in a docker compose setup. Suggested solutions to achieve this goal are (1) To place initialization scripts at /docker-entrypoint-initdb.d and do the filling of the DB when the container is started the first time -> I want to avoid this, as it takes 20 minutes (2) To mount a volume to /var/lib/postgresql and have the data there -> I want to avoid this, as it requires to move and maintain the data folder separately Not suggested (at least this is what I found at mailing lists and at StackOverflow) is to burn the data into the container image. However, the reasons that are mentioned in these discussions "data is gone when the container is gone ..." is not my concern. As it is not easy to write a Docker build to achieve my goal, I would like to ask if there are reference projects / Docker build processes that perform this workflow? Reason why I consider it as not too easy: I have to manually start the Postgres server ignoring the intended entry-point script and then fill it with my data. Looking forward to your comments/suggestions! Bernd
