title: Installing Apache Airflow 1.10.0 in kubernetes - Flask errors
body: <p>I am currently working on deploying Apache Airflow 1.10.0 to a Kubernetes cluster. I am running into some dependency issues with Flask. </p>
  
  <p>If I use the current version of flask-login (0.4.1), I receive this error:</p>
  
  <pre><code>apache-airflow 1.10.0 has requirement flask-login==0.2.11, but you'll have flask-login 0.4.1 which is incompatible.
  </code></pre>
  
  <p>With this error, the UI won’t render, and instead, I see a text bomb followed by many flask-appbuilder/flask-login warnings.</p>
  
  <p>If I use the Airflow’s requirement of flask-login (0.2.11), I receive this error: </p>
  
  <pre><code>flask-appbuilder 1.12.0 has requirement Flask-Login&lt;0.5,&gt;=0.3, but you'll have flask-login 0.2.11 which is incompatible.
  </code></pre>
  
  <p>With this error, the UI renders with Airflow 1.9 features and CeleryExecutor won’t work.</p>
