Values.yaml file

Q: How deeply does Data Pipelines with Apache Airflow, Second Edition cover values.yaml file?

Explains override structure through user, image, DAG-source, and executor configurations, stopping short of general YAML semantics.

As explained in Data Pipelines with Apache Airflow, Second Edition

A Helm values file is a configuration file containing values that parameterize a Helm chart deployment.

A values.yaml file parameterizes a Helm chart deployment by overriding selected defaults. Helm applies it during installation or upgrade, letting an Airflow deployment adopt project-specific users, images, databases, secrets, DAG sources, and executors. section 17.2.4 section 17.4

Typical overrides include:

Select a custom Docker image by setting images.airflow.repository and images.airflow.tag, then deploy it with helm upgrade. section 17.2.7
Choose DAG delivery through a persistent volume or Git synchronization, using dags.persistence or dags.gitSync settings. section 17.2.7
Configure multiple executors and task images, including CeleryExecutor and KubernetesExecutor combinations. section 17.2.9

Apply an Airflow override file

Store deployment choices in /etc/helm/values/01-user-values.yaml, then apply them with: helm upgrade --install airflow apache-airflow/airflow --namespace airflow --set apiServer.service.type=LoadBalancer -f /etc/helm/values/01-user-values.yaml. Upgrading changes the configuration without necessarily removing existing resources; an old user can therefore remain after a new initial-user setting is applied. section 17.2.4
