Types

type Bootstrapper 

type Bootstrapper interface {
	// InstallHabitat should install the `hab` binary, using the
	// version specified in the manifest.

	// InstallDeploymentService installs the deployment-service
	// package specified in the manifest.
	InstallDeploymentService(context.Context, *dc.ConfigRequest, manifest.ReleaseManifest) error

	// configuration into the systems init system. If this
	// function completes without error, the Habitat supervisor
	// should be available to load further Chef Automate services.
	SetupSupervisor(context.Context, *dc.ConfigRequest, manifest.ReleaseManifest, cli.FormatWriter) error
	// DeployDeploymentService configures and starts the
	// deployment-service. If this function exits without an

	DeployDeploymentService(ctx context.Context, cfg *dc.ConfigRequest, releaseManifest manifest.ReleaseManifest,
		bootstrapBundlePath string, writer cli.BodyWriter) error
	// SetHabitatEnvironment is a work-around for backwards
	// compatibility. It should set the PATH and HAB_SUP_BINARY
	// environment variables in the current process to ensure that
	// further Habitat interactions use the correct version of hab
	// and hab-sup. This should be called after SetupSupervisor.
	SetHabitatEnvironment(manifest.ReleaseManifest) error

We would like to avoid the KILL being sent to our data services. Shutting down services in their reverse startup order makes it more likely that data services will shut down quickly since all of their clients have been stopped.
