Tim Hockin 4318ca5a8b Rename 'portal IP' to 'cluster IP' most everywhere 
This covers obvious transforms, but not --portal_net, $PORTAL_NET and
similar.

Justin Santa Barbara e49ad95462 Mark PublicIPs as deprecated & rename to DeprecatedPublicIPs in the latest API 
We need to keep them in the API so that we can round-trip between versions.

Justin Santa Barbara 1ad4549f5f Proxy infrastructure for NodePorts 
A service with a NodePort set will listen on that port, on every node.

This is both handy for some load balancers (AWS ELB) and for people
that want to expose a service without using a load balancer.

Eric Paris 6b3a6e6b98 Make copyright ownership statement generic 
Instead of saying "Google Inc." (which is not always correct) say "The
Kubernetes Authors", which is generic.

Tim Hockin 186818d787 WIP: Implement multi-port Services 2015-03-30 19:28:11 -07:00
Alex Robinson 151b871eff Fix bug in kube-proxy of not updating iptables rules if a service's 
public IPs change, and add tests to catch the bug.

Tim Hockin 8ae203825b Implement multi-port endpoints 
Instead of endpoints being a flat list, it is now a list of "subsets"
where each is a struct of {Addresses, Ports}.  To generate the list of
endpoints you need to take union of the Cartesian products of the
subsets.  This is compact in the vast majority of cases, yet still
represents named ports and corner cases (e.g. each pod has a different
port number).

This also stores subsets in a deterministic order (sorted by hash) to
avoid spurious updates and comparison problems.

This is a fully compatible change - old objects and clients will
keepworking as long as they don't need the new functionality.

This is the prep for multi-port Services, which will add API to produce
endpoints in this new structure.

Tim Hockin 411666decb Get rid of ServiceSpec.ProxyPort 
As far as I know, nobody uses it.  It was replaced by PublicIPs.  If I were
being very polite I would leave it in internal, but since I am 99.99% sure
nobody uses it, I am cutting it.  Let's argue about it.

Tim Hockin 3b5ea74a48 Fix a race in kube-proxy causing runaways 
It was an ABA problem where the proxy loop might see its own service as
"existing" when it had been destroyed and recreated (as in an update).

To prove this I added a counter of running ProxyLoop goroutines and check that
in tests.  If I undo my main change, the tests fail.  This makes the
proxier_test significantly slower (3 seconds vs 0.5 seconds).  Sorry.

Tim Hockin e045c6ce2f Split portals into host and container 
After this DNS is resolvable from the host, if the DNS server is targetted
explicitly.  This does NOT add the cluster DNS to the host's resolv.conf.  That
is a larger problem, with distro-specific tie-ins and circular deps.

Kelsey Hightower 1d3e660248 proxy: cleanup and minor refactoring 
This change includes minor refactoring and cleanup of the proxy
package including the following items:

 * Rename source files with misspelling of round robin
 * Remove unnecessary and redundant comments
 * Update comments for clarity
 * Add locking when updating the round-robin index
 * Improve method receiver names
 * Rename the LoadBalance method to NextEndpoint to add clarity

No changes in behaviour have been introduced.

Daniel Smith b3cc696486 All types stored in etcd are now API objects. 
This means I made an api.ContainerManifestList, and added a JSONBase to
endpoints (and changed Name -> JSONBase.ID).
