When using the new deployment management, if I have multiple deployments that use the same build it build the container again for every deployment, if there a way to prevent that and only build and push the image once?

are you using different build time environments for each deployment? otherwise wouldnt docker cache your layers?

Yes it does, but prefect deploy builds the image multiple times and pushes it

hmm gotcha - maybe you could just run the docker commands in a shell script via

prefect.deployments.steps.run_shell_script

which adds some logic in a shell script?

The subsequent builds and pushes are faster

can you just have the image tag be the GITHUB_SHA and then have the shell script do something like

if docker inspect "$IMAGE:$TAG" >/dev/null 2>&1; then
    echo "Image exists"
else
    echo "Image does not exist. Building the image."
    docker build -t "$IMAGE:$TAG" .
fi

exit 0

and add this to your

defintions

in prefect.yaml and give it to each deployment as the

build

step?

I can do something like that

for each deployment definition, if you have a

build

section, it will run when you do

prefect deploy

When referencing the same build section, you would think it would know and pull in the values from the previous build

that sounds like a reasonable feature request! the tricky part i think would be deciding where to keep that state i.e. "is this build the same as the last one?" but seems doable
