host "example.com"
	& someproperty
	! oldproperty
	& otherproperty

class Hostlike h where

Something that can accumulate properties.

Methods

(&) :: IsProp p => h -> p -> h infixl 1

Adds a property.

Can add Properties and RevertableProperties

(&^) :: IsProp p => h -> p -> h infixl 1

Like (&), but adds the property as the first property of the host. Normally, property order should not matter, but this is useful when it does.

getHost :: h -> Host

Instances

Hostlike Host

Hostlike Chroot

Hostlike Container

Hostlike Container

(!) :: Hostlike h => h -> RevertableProperty -> h infixl 1

Adds a property in reverted form.

propigateInfo :: Hostlike hl => hl -> Property -> (Info -> Info) -> Property

When eg, docking a container, some of the Info about the container should propigate out to the Host it's on. This includes DNS info, so that eg, aliases of the container are reflected in the dns for the host where it runs.

This adjusts the Property that docks a container, to include such info from the container.
