![]() ![]() This will replace the default pod_template_file named in the airflow.cfg and then override that template using the pod_override. You can also create custom pod_template_file on a per-task basis so that you can recycle the same base values between multiple tasks. apiVersion : v1 kind : Pod metadata : name : placeholder-name spec : containers : - env : - name : AIRFLOW_CORE_EXECUTOR value : LocalExecutor # Hard Coded Airflow Envs - name : AIRFLOW_CORE_FERNET_KEY valueFrom : secretKeyRef : name : RELEASE-NAME-fernet-key key : fernet-key - name : AIRFLOW_DATABASE_SQL_ALCHEMY_CONN valueFrom : secretKeyRef : name : RELEASE-NAME-airflow-metadata key : connection - name : AIRFLOW_CONN_AIRFLOW_DB valueFrom : secretKeyRef : name : RELEASE-NAME-airflow-metadata key : connection image : dummy_image imagePullPolicy : IfNotPresent name : base volumeMounts : - mountPath : "/opt/airflow/logs" name : airflow-logs - mountPath : /opt/airflow/airflow.cfg name : airflow-config readOnly : true subPath : airflow.cfg restartPolicy : Never securit圜ontext : runAsUser : 50000 fsGroup : 50000 serviceAccountName : "RELEASE-NAME-worker-serviceaccount" volumes : - emptyDir : " ) except ValueError as e : if i > 4 : raise e sidecar_task = test_sharedvolume_mount () This guide is using Google Cloud Platform (GCP) as a cloud provider. There are many repositories to a deployment solution with custom helm charts, but in this repo I am only going to use a few yaml files. Also, configuration information specific to the Kubernetes Executor, such as the worker namespace and image information, needs to be specified in the Airflow Configuration file.Īdditionally, the Kubernetes Executor enables specification of additional features on a per-task basis using the Executor config. Simple Apache Airflow 1.10.9 solution using Kubernetes Executor. One example of an Airflow deployment running on a distributed set of five nodes in a Kubernetes cluster is shown below.Ĭonsistent with the regular Airflow architecture, the Workers need access to the DAG files to execute the tasks within those DAGs and interact with the Metadata repository. The worker pod then runs the task, reports the result, and terminates. When a DAG submits a task, the KubernetesExecutor requests a worker pod from the Kubernetes API. KubernetesExecutor requires a non-sqlite database in the backend. Not necessarily need to be running on Kubernetes, but does need access to a Kubernetes cluster. KubernetesExecutor runs as a process in the Airflow Scheduler. ![]() The Kubernetes executor runs each task instance in its own pod on a Kubernetes cluster. But What About Cases Where the Scheduler Pod Crashes?.Debugging Airflow DAGs on the command line.chore: release 8.6.0 by in #559 New Contributorsįull Changelog: airflow-8.5.3.airflow-8.6.fix: cast user values with toString before b64enc by in #557.feat: add airflow triggerer Deployment by in #555.feat: allow labels on sync and db-migrations Deployments/Jobs by in #467.feat: add ingressClassName value to ingress by in #527.feat: fully support helm templating in extraManifests by in #523.fix: PG_ADVISORY_LOCK are not released in pgbouncer by in #529.fix: allow ingress servicePort to be string or number by in #530.feat: add airflow.clusterDomain value by in #441.fix: only set CONNECTION_CHECK_MAX_COUNT once by in #533.fix: update default to v3.5.0 by in #544.feat: set default pgbouncer.maxClientConnections to 1000 by in #543.fix: replace pgbouncer readinessProbe with startupProbe by in #547.feat: add "task creation check" to scheduler liveness probe by in #549.feat: database passwords with values + username from secret by in #553.feat: allow to specify a list of roles by in #539. ![]() fix: set DUMB_INIT_SETSID=0 for celery workers (warm shutdown) by in #550.feat: update pgbouncer image tag 1.17.0-patch.0 by in #552.feat: add log-cleanup sidecar to scheduler/worker by in #554.feat: update pgbouncer to 1.17.0 & build for linux/arm64 by in #551.Originally created in 2018, it has since helped thousands of companies create production-ready deployments of Airflow on Kubernetes.
