Execute a task in a Kubernetes Pod

Parameters

  • image (str) – Docker image you wish to launch. Defaults to hub.docker.com, but fully qualified URLS will point to custom repositories.

  • namespace (str) – the namespace to run within kubernetes.

  • cmds (list[str]) – entrypoint of the container. (templated) The docker images’s entrypoint is used if this is not provided.

  • arguments (list[str]) – arguments of the entrypoint. (templated) The docker image’s CMD is used if this is not provided.

  • image_pull_policy (str) – Specify a policy to cache or always pull an image.

  • image_pull_secrets (str) – Any image pull secrets to be given to the pod. If more than one secret is required, provide a comma separated list: secret_a,secret_b

  • ports (list[airflow.contrib.kubernetes.pod.Port]) – ports for launched pod.

  • volume_mounts (list[airflow.contrib.kubernetes.volume_mount.VolumeMount]) – volumeMounts for launched pod.

  • volumes (list[airflow.contrib.kubernetes.volume.Volume]) – volumes for launched pod. Includes ConfigMaps and PersistentVolumes.

  • labels (dict) – labels to apply to the Pod.

  • startup_timeout_seconds (int) – timeout in seconds to startup the pod.

  • name (str) – name of the pod in which the task will run, will be used to generate a pod id (DNS-1123 subdomain, containing only [a-z0-9.-]).

  • env_vars (dict) – Environment variables initialized in the container. (templated)

  • secrets (list[airflow.contrib.kubernetes.secret.Secret]) – Kubernetes secrets to inject in the container. They can be exposed as environment vars or files in a volume

  • in_cluster (bool) – run kubernetes client with in_cluster configuration.

  • cluster_context (str) – context that points to kubernetes cluster. Ignored when in_cluster is True. If None, current-context is used.

  • get_logs (bool) – get the stdout of the container as logs of the tasks.

  • annotations (dict) – non-identifying metadata you can attach to the Pod. Can be a large range of data, and can include characters that are not permitted by labels.

  • resources (dict) – A dict containing resources requests and limits. Possible keys are request_memory, request_cpu, limit_memory, limit_cpu, and limit_gpu, which will be used to generate airflow.kubernetes.pod.Resources. See also kubernetes.io/docs/concepts/configuration/manage-compute-resources-container

  • affinity (dict) – A dict containing a group of affinity scheduling rules.

  • node_selectors (dict) – A dict containing a group of scheduling rules.

  • config_file (str) – The path to the Kubernetes config file. (templated)

  • do_xcom_push (bool) – If do_xcom_push is True, the content of the file /airflow/xcom/return.json in the container will also be pushed to an XCom when the container completes.

  • is_delete_operator_pod (bool) – What to do when the pod reaches its final state, or the execution is interrupted. If False (default): do nothing, If True: delete the pod

  • hostnetwork (bool) – If True enable host networking on the pod.

  • tolerations (list tolerations) – A list of kubernetes tolerations.

  • configmaps (list[str]) – A list of configmap names objects that we want mount as env variables.

  • pod_runtime_info_envs (list[PodRuntimeEnv]) – environment variables about pod runtime information (ip, namespace, nodeName, podName).

  • security_context (dict) – security options the pod should run with (PodSecurityContext).

  • dnspolicy (str) – dnspolicy for the pod.
