Docker images with zstd using Depot?

[hilja]

I just read this Try out faster machine creation with zstd . It shows how to make a new builder machine which is configured to use zstd for Docker compression.

But it was written before the move to Depot. If I now create a custom builder machine, will it be a Depot builder?

Or is there a way to pass –-output options to fly deploy? I only really see --build-args.

Thanks

You want --depot=false to use a non-Depot builder.

It’s not documented very well, but a while back we added an experimental.use_zstd = true flag you can set in fly.toml that will allow you to build zstd-compressed images on remote Depot builders.

Very nice! I’ll give that a try.
