Dependency chain is now api -> api/rest -> apiserver. Makes the
interfaces much cleaner to read, and cleans up some inconsistenties
that crept in along the way.
This commit adds support to core resources to enable deferred deletion
of resources. Clients may optionally specify a time period after which
resources must be deleted via an object sent with their DELETE. That
object may define an optional grace period in seconds, or allow the
default "preferred" value for a resource to be used. Once the object
is marked as pending deletion, the deletionTimestamp field will be set
and an etcd TTL will be in place.
Clients should assume resources that have deletionTimestamp set will
be deleted at some point in the future. Other changes will come later
to enable graceful deletion on a per resource basis.
In order to support graceful deletion, the resource object will
need access to the TTL value in etcd. Also, in the future we
may want to get the creation index (distinct from modifiedindex)
and expose it to clients. Change EtcdResourceVersioner to be
more type specific (objects vs lists) and provide a default
implementation that relies on the internal API convention.
Also, rename etcd_tools.go to etcd_helper.go and split a few
things up.
Allows POST to create a binding as a child. Also refactors internal
and v1beta3 Binding to be more generic (so that other resources can
support Bindings).
PUT /api/v1beta3/namespaces/default/pods/foo/status
{
"metadata": {...}, // allowed for valid values
"spec": {}, // ignored
"status": {...}, // allowed, except for Host
}
Exposes the simplest possibly change. Needs a slight refactoring
to RESTUpdateStrategy to split merging which can be done in a
follow up.
