Kubernetes Pods

By default Flyte tasks - @task are essentially single functions that are loaded in one container. But, often times there is a need to run a job, with more than one containers. For example,

  • a special Hyper-parameter optimizer with state stored in a redis db

  • simulating a service locally

  • run a sidecar to fetch or orchestrate data, handle additional logging or monitoring

  • run a pod with it’s complete set of possibilities- mounting volumes etc

In this case, a regular task is not enough. For such a case, users can simply use a kubernetes pod abstraction provided by Flyte to execute multiple containers. This can be done by using Pod task_config can be leveraged to fully customize the pod spec used to run your task.


Flyte will automatically take care of pod tasks. Typically a K8s pod will not exit, if the pod contains any sidecars (containers that do not exit automatically). No additional code is required.


To use the flytekit pod plugin simply run the following:

pip install flytekitplugins-pod
