Prefect Community

is there an easy way to log into docker hub during the build (not push) step? The docker images we build use `prefecthq/prefect` . but without authenicating to dockerhub, we are getting rate limited.

I would expect the step to use the creds is passed
But per this: <https://github.com/PrefectHQ/prefect-docker/blob/main/prefect_docker/deployments/steps.py#L184C34-L184C34>
it seems that it would only use the credentials if pushing during the build step (which is disabled by default)

is this running as part of a CI pipeline? I've handled this before by running `docker login` in the step prior to `prefect deploy`

that way both build and push are already authenticated when they run

The build needs to auth to dockerhub. but the push needs to auth against AWS ECR

i assume this would be fine, if i provide aws creds to the push step

I haven't tried that exact setup but it's worth a try
