Scheduler uses Reflector from pkg/client/cache.
It defines some helper classes.
I'd like to use those helpers with pkg/client/cache
in kube-proxy and kubelet too.
There are quite a few 'composite literal uses unkeyed fields' errors that I have kept out of this patch.
And there's a couple where vet just seems confused. These are the easiest ones.
RESTClient is an abstraction for simplifying access to resources that
follow the Kubernetes API pattern. Currently, both Namespace and Path
are coupled, which means changes across versions is complex. In general,
most access to resources should be to a resource collection (e.g.
"services") with a name (e.g. "foo"). Other constructs, like prefix sections
("watch") or proposed suffix sections ("/pods/foo/spec") only modify this
core pattern.
This commit removes the Path() helper from Request and introduces:
* Prefix(segments ...string) - segments that should go to the beginning of the path.
* Suffix(segments ...string) - segments that should go to the end of the path.
* Resource(string) - collection name, should be after prefix
* Namespace(string) - if specified, should be set after resource but before name
* Name(string) - if specified, should be after namespace
Now, only Prefix and Suffix are order dependent (and with variadics, should be
simpler). Resource, Namespace, and Name may be specified in any order.
Path() has been removed to prevent downstream consumers of RESTClient from experiencing
behavior change.
Watch depends on long running connections, which intervening proxies
may break without the control of the remote server. Specific errors
handled are io.EOF, io.EOF wrapped by *url.Error, http connection
reset errors (caused by race conditions in golang http code), and
connection reset by peer (simply tolerated).
Add a Visitor pattern on top of ResourcesFromArgs
Allows ResourcesFromArgs to return an opaque list of items and have client
commands react to them.
Change request.go to return apiserver errors for arbitrary status codes to
better respond to generic actions that don't make sense (kubectl delete operations foo)
Replaces the client public interface but leaves old references to "minions"
for a later refactor. Selects the path "nodes" for v1beta3 and "minions"
for older versions.
