These three components need to be set up before the deployment of the OpenMetadata resource. OpenMetadata uses MySQL for the metadata catalog and Elasticsearch to store the Entity change events and makes them searchable by search index. The next image showcases all of the OpenMetadata dependencies: Elasticsearch, MySQL, and Airflow, and their positions in the OpenMetadata end-to-end metadata platform. On every cloud-managed cluster, you have to manually configure the persistent volume to work in the desired access mode because the default mode is ReadWriteOnce, and the same applies to Azure and its Kubernetes service, AKS. Are you willing to submit PR Yes I am willing to submit a PR Code of Conduct. OpenMetadata helm charts depend on Airflow, and Airflow expects a persistent disk that supports ReadWriteMany access mode (the volume can be mounted as read-write by many nodes). If the maintainers think is a valid bug, I will be more than happy to submit a PR. The main reason for cloud-specific instructions are the inner workings of Airflow. This might change in the near future, as stated in this GitHub request by one of the OpenMetadata developers. OpenMetadata currently provides EKS and GKE-specific deployment instructions on their official page, but there are no instructions when it comes to deployments on AKS. We aim to keep backwards compatibility of the Helm Chart with all released Airflow 2 versions, but some new features might only work starting from specific Airflow releases. Lets say at /opt/airflow/dags/my/dagdirectory/ Now if you want the DAGS to be loaded from just the folder dagdirectory. Originally created in 2017, it has since helped. By enabling the persistence you refer to the PVC which is mounted in the airflow container. The User-Community Airflow Helm Chart is the standard way to deploy Apache Airflow on Kubernetes with Helm. SemVer MAJOR and MINOR versions for the chart are independent from the Airflow version. 1 Answer Sorted by: 0 In the official Helm Chart You wont have a subpath folder. Keep in mind that the review was written prior to the 1.0.0 release, which contain ed some interesting new features.Īll three major cloud providers offer the option of using their managed versions of Kubernetes clusters: Airflow Helm Chart: SemVer rules apply to changes in the chart only.
