Heya, we're using Dagster Serverless. One of our dependencies in

requirements.txt

has some system dependencies needed to install it (it's not a pre-built package). I thought that using a custom base image would solve this, but I'm getting an error from Github Actions on the deploy workflow showing that the requirement is failing to build. Is custom base image just for runtime dependencies? If so, how can I get this working? Thanks.

Hi Sim - yes the custom base image is only used for the runtime. The build itself happens on the Github-hosted runner. Is your system dependency available publicly? The easiest way to handle that is to install it in your github workflow before building the dagster code.

Gotcha, thanks, I'll try that. Is just a couple of apt installs 🙂
