Anyone have any examples of running a DockerContainer deploy

Question

Anyone have any examples of running a DockerContainer deployment in Prefect 2 0 GA Non of the documentation is correct that is referenced in the migration guide and even the tutorial I found with the correct code had the wrong CLI commands and the new commands that would appear to be equivalent ignores the Deployment function in the script

Khuyen Tran · Answer

Hi Seth we no longer have the `Deployment ` function and replace it with a deployment manifest and `deployment yaml` instead You can find the updated docs about deployment <https orion docs prefect io tutorials deployments build a deployment|here> Basically you can run ```prefect deployment build lt path to your flow gt lt your flow gt n lt deployment name gt t lt tag gt i DockerContainer``` to run your flows in a Docker container We will update the docs for this as soon as possible

Thanks for the quick assistance that does help

Does this also mean that you no longer support the register + build formula Just trying to figure out how big of a lift this is going to be for us coming from 1 2 where everything we do is in custom docker images that include our custom packages

Currently we do this for storage but I don t see the equivalent in 2 0 Is this something we are going to need to wait on for a solution ```Flow attach files storage=Docker registry url= <http myrepo azurecr io prefect runsheets|myrepo azurecr io prefect runsheets> dockerfile= devcontainer Dockerfile as flow ```

This looks promising <https orion docs prefect io api ref prefect packaging prefect packaging docker DockerPackager>

I have a similar question to Seth here I did notice the packaging class information was removed from the Concepts page recently is this functionality going to be deprecated or is this still the intended way to build and point to docker images in deplpoyments ala DockerStorage in Prefect 1 0

Khuyen Tran · Answer

Using packaging is depreciated The alternative to packaging is specifying <https orion docs prefect io concepts infrastructure |infrastructure> in the `prefect deployment build` command The specific command is ```prefect deployment build lt path to file gt lt flow name gt n lt deployment name gt i docker container```

Thank you for clarifying Khuyen

Hi < Khuyen Tran> sorry to bug you about this again but I am looking over the documentation and am a little confused if we were to use this docker container infrastructure flag does this actually generate an image and place it somewhere and if so would that the image built would also only be operable from a Docker flowrunner In our case we are looking for replacement functionality similar to from 1 0 that allows us to use that image in any runner class i e KubernetesRun or `KubernetesJob` in the 2 0 world To do this would we instead need to follow the strategy found here and point to it when configuring our `KubernetesJob` infrastructure It seems like the packaging module did this before but unless I m misunderstanding doing `prefect deployment build i docker container` does not have the same functionality
