Choosing a Base Domain for Astronomer


You need to choose a base domain for your Astronomer installation, something like astro.mydomain.com. Each Airflow cluster you install will be accessible at a URL like unique-name-airflow.astro.mydomain.com and the admin application will be installed to app.astro.mydomain.com, the Grafana dashboard will be installed to grafana.astro.mydomain.com etc.

You will need to edit the DNS for this domain. If you work for a big company it might be easier to just register a new domain like astro-mycompany.com that you'll have full control of, and Astronomer can be installed on that root domain (app.astro-mycompany.com etc).

Note: For the purpose of our tutorial, our application domain is astro.mycompany.com.
