@Marvin I have a prefect.yaml with build and push steps to make a single docker container and push to GCR. It seems to run those steps for each deployment even though they all use the same container. How do I fix that?

It looks like you're dealing with Prefect deployments, and you want to avoid rebuilding the same Docker container for each deployment when they all use the same container. In both Prefect 2.x and 3.x, you can make use of built-in features to optimize this. Here's how you can handle it: 1. Version Your Images: - Make sure your build steps in the

prefect.yaml

create an image with a specific name and tag. By doing so, the same image can be reused, preventing unnecessary rebuilds. Prefect documentation suggests using

image_name

and

tag

fields in the build step. For example:

build:
       - prefect_docker.deployments.steps.build_docker_image:
           image_name: my-repo/my-image
           tag: my-tag

2. Reference Built Images: - Use these generated names and tags in your deployments to make sure you reference the pre-built image:

{{ build-image.image }}

or directly use

image_name: bobs-burgers/latest

. 3. Avoid Rebuilding: - You can set

build: false

for deployments if the image has already been built and is available in your registry. This can be done in the

prefect.yaml

by setting:

deploy:
       build: false

4. Use the Same YAML Across Deployments: - Although Prefect supports multiple deployment configurations in a single

prefect.yaml

, ensure each deployment correctly references the same container details to avoid rebuilding. For more information, you might want to check the Prefect documentation: - Prefect 2.x: https://docs-2.prefect.io/latest/guides/prefect-deploy/ - Prefect 3.x: https://docs-3.prefect.io/3.0/deploy/infrastructure-concepts/prefect-yaml You're after efficiency, not redundancy—unless you're in a quantum state, but that's another conversation.
