Deploying the project on Union ​

Deploying your project ​

The process of deploying is called registration. The phrase "register your workflow" means the same things as "deploy your workflow".

Register the workflow ​

shell
$ pyflyte register workflows --project wine-classification

This command does the following:

  • Builds the images defined by the ImageSpec objects in your code and pushes them to the specified container registry.
  • Pushes the workflow code to Union.
  • Sets up the workflow DAG and its constituent task containers.
  • Registers the workflow in the dev domain of your wine-classification project in Union (which, recall, you have already created with uctl).

Make your image public ​

Before you can run the workflow from the Union interface, you must make sure that the image define in your ImageSpec is public.

In the GitHub Container Registry, switch the visibility of your container image to Public. For more information, see Configuring a package's access control and visibility.

At this point, you can run the workflow from the Union interface.

A common error: An inaccessible image

If you try to run a workflow that uses a private container image or an image that is inaccessible for some other reason, the system will return an error:

... Failed to pull image ...
... Error: ErrImagePull
... Back-off pulling image ...
... Error: ImagePullBackOff
