Alpha Stack is a declarative DevOps software development kit (SDK) to publish data-driven applications in production. As a cohesive stack, it seamlessly integrates with web-server-based application images constructed atop DataOS, empowering users to leverage DataOS's Compute Resource to execute external tools or applications. With Alpha Stack, application development is no longer bound by programming language constraints, as it enables the fluid deployment of diverse applications onto a robust, flexible infrastructure.

When deploying an application using Alpha Stack, the containerized image contains all the essential functionalities and logic required for the application, while execution of the image occurs within DataOS via the utilization of Alpha Stack, which can be invoked or called within a Service or a Workflow Resource.

Getting Started with Alpha Stack

Deploying Images from a Public DockerHub Repository

To begin the journey with Alpha Stack, let’s take an image already available on the public DockerHub repository and run it atop DataOS through Alpha Stack. To know more, navigate to the link below:

Deploying Images from a Private DockerHub Repository

You can also deploy custom-built images from a private DockerHub repository. To know more about this case scenario, navigate to the link below:

Resource Section

Alpha Stack can be implemented or executed via a Workflow or as a Service. Workflow/Service are DataOS Resources and are both provisioned as runnable. To know more about the YAML configurations for a Workflow/Service, refer to any of the below two sections:



Alpha Stack-specific Section


All the configuration fields and values for the Alpha Stack are provided within the Alpha section.

  {} # All the fields and values for the Alpha stack are specified here


The path to the respective Docker Image within the DockerHub repository.

Type: string

Default: NA

image: swagger/swagger-ui # Path of the Docker Image


This includes the commands that are mentioned within the CMD section of the Docker file.

For e.g., If the below is your Docker File, then the commands are provided within the CMD section:

# Dockerfile

FROM python:3.8-slim-buster

RUN pip install streamlit


CMD ["streamlit", "run", ""]
#     command      arguments 1 & 2


  - streamlit


The arguments are the additional arguments apart form the primary command specified within the Dockerfile, as described above

  - run
