The constraint + files are managed by Apache Airflow release managers to make sure that you can repeatably install Airflow from PyPI with all Providers and + required dependencies. + +* In case of PyPI installation you could also verify integrity and provenance of the packages of the packages + downloaded from PyPI as described at the installation page, but software you download from PyPI is pre-built + for you so that you can install it without building, and you do not build the software from sources. + +**Intended users** + +* Users who are familiar with installing and configuring Python applications, managing Python environments, + dependencies and running software with their custom deployment mechanisms. + +**What are you expected to handle** + +* You are expected to install Airflow - all components of it - on your own. +* You should develop and handle the deployment for all components of Airflow. +* You are responsible for setting up database, creating and managing database schema with ``airflow db`` commands, + automated startup and recovery, maintenance, cleanup and upgrades of Airflow and Airflow Providers. + +**What Apache Airflow Community provides for that method** + +* You have :doc:`/installation/installing-from-pypi` + on how to install the software but due to various environments and tools you might want to use, you might + expect that there will be problems which are specific to your deployment and environment you will have to + diagnose and solve. +* You have :doc:`/start/local` where you can see an example of Quick Start with running Airflow + locally which you can use to start Airflow quickly for local testing and development. + However this is just an inspiration. Do not expect this docker-compose is ready for production installation, + you need to build your own production-ready deployment in this approach. + +**Where to ask for help** + +* The ``#troubleshooting`` channel on Airflow Slack for quick general + troubleshooting questions.

It provides a capability of +running Airflow components in isolation from other software running on the same physical or virtual machines with easy +maintenance of dependencies. + +The images are build by Apache Airflow release managers and they use officially released packages from PyPI +and official constraint files- same that are used for installing Airflow from PyPI.
