Expand description

BuildConstraints represents certain conditions that must be fulfilled inside the build environment to be able to build this. Constraints can be things like required architecture and minimum amount of memory. The required input paths are not represented in here, because it wouldn’t be hermetic enough - see the comment around inputs too.

Fields§

§system: String

The system that’s needed to execute the build. Must not be empty.

§min_memory: u64

The amount of memory required to be available for the build, in bytes.

§available_ro_paths: Vec<String>

A list of (absolute) paths that need to be available in the build environment, like /dev/kvm. This is distinct from the castore nodes in inputs. TODO: check if these should be individual constraints instead. These MUST be clean absolute paths, without any “.”, “..”, or superfluous slashes, and sorted.

§network_access: bool

Whether the build should be able to access the network,

§provide_bin_sh: bool

Whether to provide a /bin/sh inside the build environment, usually a static bash.
