There is an occasional downside with the Postgres container though... no automatic upgrade path between major versions: https://github.com/docker-library/postgres/issues/37 https://github.com/docker-library/postgres/issues/37 So, if you want to keep on a supported version of PostgreSQL then every few years you'll need to figure something out. Hopefully that gets fixed at some point though. My in-development "automatically upgraded PostgreSQL" container is about ~400MB though, which is ~200MB more than the standard one. For my use-cases the extra space isn't relevant, but for other people it probably would be.
