Generate SSH keys and add the public key to your Git repository's deploy keys. Access to a private Git repository containing DAGs.Here's a step-by-step guide: Prerequisites Integrating Apache Airflow with Git using Helm Chart requires setting up the gitSync parameters in the values.yaml file. Remember to monitor the performance and consistency of your DAGs, especially when using Git Sync with networked volumes or persistence solutions. Sidecar Containers: For continuous synchronization, Git Sync can run as a sidecar container in your scheduler, webserver, and worker pods, syncing the DAGs at a specified interval.ĭAG Serialization: With Airflow >= 2.0.0, DAG serialization is enabled by default, which means the webserver doesn't need access to DAG files, and the Git Sync sidecar isn't required on the webserver.Įxample Usage: The official documentation provides examples of how to use Git Sync, including YAML configurations and Helm chart commands. This approach requires careful management of submodule linking and versioning. Submodules: If you need to synchronize multiple Git repositories, consider using Git submodules with an umbrella repository. Persistence: While combining Git Sync with DAG persistence is possible, it's not typically recommended due to potential side effects like performance drops and increased networking traffic. Refer to the production guide for setting up known hosts. Security: It's crucial to set to prevent man-in-the-middle attacks. ![]() Here's how to set it up and some considerations:Ĭonfiguration: To enable Git Sync, you need to configure your Airflow Helm chart with the necessary parameters, such as the Git repository URL, branch, and the SSH key secret for private repositories. This is particularly useful for teams that want to manage their workflows as code, enabling version control and collaboration. Apache Airflow's Git Sync feature allows for the synchronization of DAGs from a Git repository to the Airflow environment. ![]()
