Extending Airflow Web UI and adding Static HTML pages and CSS
Faced a similar issue: I had to show images in doc_md of a DAG.Long story short we need to configure a Blueprint properly to host static files and templates.
Following works for me for airflow=1.10.14.
test_plugin.py
from airflow.plugins_manager import AirflowPluginfrom flask import Blueprintfrom flask_admin import base, BaseView, expose# Creating a flask admin BaseViewclass TestView(BaseView): @expose('/') def list(self): return self.render("index.html", content="")v = TestView(category="Test Plugin", name="Test View")# Creating a flask blueprint to integrate the templates and static folderbp = Blueprint( "test_blueprint", __name__, template_folder='templates/testview', static_folder='static/testview', static_url_path='/admin/testview/static')class AirflowTestPlugin(AirflowPlugin): name = "test_plugin" admin_views = [v] flask_blueprints = [bp]index.html
