Good morning all! I am noticing something odd. Whenever I deploy my stack though my CI pipeline (github actions) it updates the cdn even though nothing has changed regarding the cdn. Is there something I should be caching in the pipeline to avoid this? In my specific case I was only making changes to the github workflows but CDN kept updating making the builds take 10+ minutes

Do you have a staticsite in your stack?

yes

I was just talking to the team about this issue. The way it works right now is it builds your static site and if the resulting bundle is different, it goes through a deploy otherwise it can skip (cc @Frank correct me if I'm wrong) Is there something that's causing your static site builds not to be deterministic?

Can i just run

sst build

and compare one bundle to another to check that?

You can do an

sst diff --stage <name>

and it'll build and compare against what's deployed

yep there are differences but im not sure why that would be

do you see a difference in the s3 bundle for the static site?

And the CDN so that answers why it was updating with every deploy

Let me verify we're not doing something weird

could it be related to this? https://stackoverflow.com/questions/61848022/cdk-adds-random-parameters

Hey guys, it is likely the s3 assets are different on each build.

the only thing I was changing on each push was code in my github workflows for several builds

Can you show me what’s in ur

.build

?

will do
