# Build state model

The Gradle daemon tracks state for various elements. These are arranged in a hierarchy:

```mermaid
  graph TD

  process["build process"]
  
  session["build session"]
  process --> session
  
  build_tree["build tree"]
  session --> build_tree
  
  build1["root build"]
  build_tree --> build1
  
  project1["root project"]
  build1 --> project1
  
  project2["project"]
  build1 --> project2

# There are two use cases here:
# * Building all docker images (generally in CI). In this case we want to build everything at once, so they share work
# * Building a single docker image (generally during dev). In this case we just want to build the single binary alone
BUILD_ALL ?= true
define build-linux
.PHONY: $(TARGET_OUT_LINUX)/$(shell basename $(1))
ifeq ($(BUILD_ALL),true)

	// Append our rules here
	builder := cfg.appendInpodRules(hostProbeSNAT)

	if err := cfg.addLoopbackRoute(); err != nil {
		return err
	}

	if err := cfg.addInpodMarkIPRule(); err != nil {
		return err
	}

	log.Debug("Adding iptables rules")
	if err := cfg.executeCommands(builder); err != nil {
		log.Errorf("failed to restore iptables rules: %v", err)

The build cache has anonymous read access, so you don't need to authenticate in order to use it. You can use a different build cache node by specifying `-DcacheNode=us` for a build cache node in the US or `-DcacheNode=au` for a build cache node in Australia.
