Heap out of memory during build

[Arctomachine]

I am trying to host studio on low memory (1 GB) VPS using docker-compose.
Running sanity build script fails with FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory during - Minifying JavaScript bundles step.
What can I do to be able to run it successfully?

I tried to apply --max-old-space-size=2048, as it was suggested in multiple sources. I tried 2 different approaches, yarn build --max-old-space-size=2048 inside dockerfile and sanity --max-old-space-size=2048 build inside package.json, but neither of them made it work.
