Airflow Run

Python tool for deploying Airflow Multi-Node Cluster.

Requirements

• Python >=3.6 (tested)

Goal

Steps

1. Generate config yaml file.

2. Run commands to start webserver, scheduler, worker, (rabbitmq, postgres).

3. Add dag files and run initdb.

Generate config file:

afr --generate_config

Running the tool in the same directory as config file:

afr --run postgresql
afr --run initdb
afr --run rabbitmq
afr --run webserver
afr --run scheduler
afr --run worker --queue {queue name}
afr --run flower

Or, running the tool specifying config path:

afr --run postgresql --config /path/config.yaml

Or, use this environment variable to set the config path:

export AIRFLOWRUN_CONFIG_PATH="/some_path/config.yaml"

After running webserver, scheduler and worker (postgres and rabbitmq if needed local instances), Add your dag files in the dags subdirectory in the directory you defined in the config file.

(* note: make sure you have the correct user permission in the dags, logs subdirectories.)

That is it!!
