# Bitnami package for SCDF Composed Task Runner
|
|
|
|
## What is SCDF Composed Task Runner?
|
|
|
|
> The Spring Cloud Composed Task Runner is a helper used by the Data Flow server to parse a directed graph DSL, launch the task definition specified in an instance, and check task completion status.
|
|
|
|
[Overview of SCDF Composed Task Runner](https://github.com/spring-cloud/spring-cloud-dataflow)
|
|
|
|
## TL;DR
|
|
|
|
```console
|
|
docker run --name spring-cloud-dataflow-composed-task-runner bitnami/spring-cloud-dataflow-composed-task-runner:latest
|
|
```
|
|
|
|
## Why use Bitnami Images?
|
|
|
|
* Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
|
|
* With Bitnami images the latest bug fixes and features are available as soon as possible.
|
|
* Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
|
|
* All our images are based on [**minideb**](https://github.com/bitnami/minideb) -a minimalist Debian based container image that gives you a small base container image and the familiarity of a leading Linux distribution- or **scratch** -an explicitly empty image-.
|
|
* All Bitnami images available in Docker Hub are signed with [Notation](https://notaryproject.dev/). [Check this post](https://blog.bitnami.com/2024/03/bitnami-packaged-containers-and-helm.html) to know how to verify the integrity of the images.
|
|
* Bitnami container images are released on a regular basis with the latest distribution packages available.
|

|
|
## Only the latest stable branch maintained in the free Bitnami catalog
|
|
|
|
Starting December 10th, 2024, only the latest stable branch of each container image will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches (e.g., LTS), consider upgrading to Bitnami Premium. Previously released versions will not be deleted and will remain available for pulling from DockerHub.
|
|
|
|
Please check the Bitnami Premium page in our partner [Arrow Electronics](https://www.arrow.com/globalecs/na/vendors/bitnami?utm_source=GitHub&utm_medium=containers) for more information.

|
|
|
## Supported tags and respective `Dockerfile` links
|
|
|
|
Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html).
|
|
|
|
You can see the equivalence between the different tags by taking a look at the `tags-info.yaml` file present in the branch folder, i.e `bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml`.

|
## Get this image
|
|
|
|
The recommended way to get the Bitnami spring-cloud-dataflow-composed-task-runner Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/spring-cloud-dataflow-composed-task-runner).
|
|
|
|
```console
|
|
docker pull bitnami/spring-cloud-dataflow-composed-task-runner:latest
|
|
```
|
|
|
|
To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/spring-cloud-dataflow-composed-task-runner/tags/) in the Docker Hub Registry.
|
|
|
|
```console
|
|
docker pull bitnami/spring-cloud-dataflow-composed-task-runner:[TAG]
|
|
```
|
|
|
|
If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.
|
|
|
|
```console
|
|
git clone https://github.com/bitnami/containers.git
|
|
cd bitnami/APP/VERSION/OPERATING-SYSTEM
|
|
docker build -t bitnami/APP:latest .
|
|
```
