The PostgreSQL object-relational database system provides reliability and data integrity. This is an usage guide for a Flask with Postgres application. Before starting, install Compose. Start by setting up the files needed to build the app. Defining dependencies is done using a file called Dockerfile.

Built For Developers. Simple drag-and-drop UI. Running PostgreSQL in production environment may require additional changes in the PostgreSQL or docker configurations.

It allows us to build and replicate images on any host, removing the inconsistencies of dev environments and reducing onboarding timelines considerably. Thanks for contributing an answer to Stack Overflow ! Please be sure to answer the question. Provide details and share your research!
