Allow cloud providers to return a node identifier different from the hostname
2015-06-18 12:40:05 -07:00
dee8d4b90b
For kubelet, differentiate between the nodeName and the hostname
...
This will allow us to use a nodeName that is not the hostname,
for example on clouds where the hostname is not the natural identifier
for a node.

fmt.Fprintf() problems, debuging on the error message people used.

Sync static pods from Kubelet to the API server
...
Currently, API server is not aware of the static pods (manifests from
sources other than the API server, e.g. file and http) at all. This is
inconvenient since users cannot check the static pods through kubectl.
It is also sub-optimal because scheduler is unaware of the resource
consumption by these static pods on the node.
This change syncs the information back to the API server by creating a
mirror pod via API server for each static pod.
- Kubelet creates containers for the static pod, as it would do
normally.
- If a mirror pod gets deleted, Kubelet will re-create one. The
containers are sync'd to the static pods, so they will not be
affected.
- If a static pod gets removed from the source (e.g. manifest file
removed from the directory), the orphaned mirror pod will be deleted.
Note that because events are associated with UID, and the mirror pod has
a different UID than the original static pod, the events will not be
shown for the mirror pod when running `kubectl describe pod
<mirror_pod>`.

Refactoring cAdvisor interface into a package.
...
This will make it easier to start running the real cAdvisor alongside
Kubelet. This change is primarily no-op refactoring. The main behavioral
change is that we always create a cAdvisor interface and expect it to
always be available. When we make a request, if cAdvisor is not
connected the request fails with a connection error. This failure is
handled today as well.

Kublet watches Pods.
...
Added a kubelet config source for watching pods on apiserver.
The pods are converted to boundpods for merging with other
config sources.
The preferred way to create a kubelet is now to pass an apiserver
client but not an etcd client. Changed cmd/integration to use
apiserver to talk to kubelets. And cmd/kubernetes.
Unit, integration, and e2e tests pass, except for a failure of the pd
e2e test which was unrelated.

0c5d9ed0d2
Implements a credentialprovider library for use by DockerPuller.
...
This change refactors the way Kubelet's DockerPuller handles the docker config credentials to utilize a new credentialprovider library.
The credentialprovider library is based on several of the files from the Kubelet's dockertools directory, but supports a new pluggable model for retrieving a .dockercfg-compatible JSON blob with credentials.
With this change, the Kubelet will lazily ask for the docker config from a set of DockerConfigProvider extensions each time it needs a credential.
This change provides common implementations of DockerConfigProvider for:
- "Default": load .dockercfg from disk
- "Caching": wraps another provider in a cache that expires after a pre-specified lifetime.
GCP-only:
- "google-dockercfg": reads a .dockercfg from a GCE instance's metadata
- "google-dockercfg-url": reads a .dockercfg from a URL specified in a GCE instance's metadata.
- "google-container-registry": reads an access token from GCE metadata into a password field.

s/log.Fatalf/glog.Fatalf/
s/log.Fatal/glog.Fatal/
4) convert glog.Info.*, err into glog.Error*
Adds some util interfaces to logging and calls them from each cmd, which
will set the default log output to write to glog. Pass glog-wrapped
Loggers to etcd for logging.
Log files will go to /tmp - we should probably follow this up with a
default log dir for each cmd.
The glog lib is sort of weak in that it only flushes every 30 seconds, so
we spin up our own flushing goroutine.
