Git synchronization

As explained in Data Pipelines with Apache Airflow, Second Edition

Git synchronization is the process of automatically copying the current contents of a Git repository into another environment.

Git synchronization deploys Airflow DAGs by copying them from a Git repository into the Airflow environment. Helm configuration enables the git-sync container, selects a repository revision, and points Airflow to the DAG subpath. section 17.2.7

Synchronizing DAGs from Git

Enable dags.persistence.gitSync, set the repository URL, choose master as the branch and ref, use depth 1, and set subPath to chapter02/dags; then apply the deployment with Helm.

How Data Pipelines with Apache Airflow, Second Edition covers it

How deep it goes
Explains repository, revision, clone-depth, failure, and subpath settings, but not synchronization internals.
Examples
Uses a chapter02/dags subpath, master revision, shallow clone, Helm values, and a visible git-sync container.
What it assumes
Assumes familiarity with Airflow deployment, Helm values, Kubernetes pods, and Git repository revisions.
What you can do after
Configure Airflow DAG synchronization through Helm and verify the deployed git-sync container with kubectl.
How it connects
Connects Airflow DAG deployment with Git repositories, Kubernetes containers, and Helm charts.
