For example, this slims down the airflow-operator image from 615MiB to 147MiB. This improvement is a combination of the size of the debuginfo itself (~200MiB per binary), and not having to include build dependencies just because our debuginfo refers to them (primarily, this ended up pulling in GCC, which sits at ~260MiB just on its own).

Yeah that's still pretty slow, but also not super actionable without a before-number to compare against (also, is this a fresh or incremental build?). I obviously think there's more work to be done eventually, but if it's at least a net improvement then I'd be inclined to say that's future work. |

Primarily by disabling debug info.
For example, this slims down the airflow-operator image from 615MiB to 147MiB, and takes the incremental redeploy time from 57s to 29s (on my machine).
This improvement is a combination of the size of the debuginfo itself (~200MiB per binary), and not having to include build dependencies just because our debuginfo refers to them (primarily, this ended up pulling in GCC, which sits at ~260MiB just on its own).
The old behaviour (useful if you want to run it under a debugger.. though we probably want to support that separately somehow) can be restored by adding
--arg debuginfo 2to thenix-buildcall.In addition, this PR adds an option to remove the shell (and associated utililties) from the built images. This can be done by setting
--arg includeShell false, but is disabled by default because not all operators are compatible yet (in particular: stackabletech/secret-operator#608).
