Installing and running the Apache Airflow single node is quite simple. Follow these steps:

1. Install Python 3.6+ (https://www.python.org/downloads/)
2. From the command console with administrative privileges, run the following commands:

$ mkdir airflow
$ cd airflow
$ mkdir dags
$ mkdir plugins
$ pip install apache-airflow

3. Export AIRFLOW_HOME with the following commands based on OS:

• • On Windows, this is done as follows:

$ set AIRFLOW_HOME=<current directory>

• • On macOS or Linux, this is done as follows:

$ export AIRFLOW_HOME=$(pwd)

4. Initialize the database with the following command:

$ airflow initdb

We are now ready to start Airflow. Follow these steps:

1. Start the scheduler:

$ airflow scheduler

2. Start the web interface with the following command:

$ airflow webserver -p 9999

We can now open the browser to http://localhost:9999:

We now have to define our connection to KairosDB. Unfortunately, Airflow doesn't have a connection to KairosDB, but this can be easily created by building a simple operator.
