zhengguoyong bff8334db9 Consistent import kubelet app package name 2015-11-28 08:51:39 +08:00
Clayton Coleman bb79365e2a Split kubelet server initialization into two parts 
First is initializing a KubeletConfig that starts no background
processes. Second is running the config. Provide a legacy path
that won't impact older callers while making it easier to customize
the interfaces passed to the Kubelet.

Used by OpenShift to inject some custom interfaces to the Kubelet
for config management.

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.

Eric Paris 036937227f Use Fprintf to print formatted strings 
Shouldn't be using Fprint() with a format string.

Eric Paris 8e7d14196f Fix printing errors from failed binary runs 
I had the kublet die on startup and the only error was "0x401da0"  Which
I assume is an address of the err.Error function.  The other way to fix
this, I think, would be to use err.Error(), however that could cause
fmt.Fprintf() problems, debuging on the error message people used.

Now I get a nice clean error I can understand:

"cAdvisor.New() err = mountpoint for cpu not found"

Joe Beda 76df5471b5 Covert the kubelet binary to hyperkube. 
This leaves `pkg/kubelet/server/server.go` looking a little ugly as there is an extra layer of "config" structs that isn't needed.  This is left as a TODO for now.
 2015-02-02 14:03:13 -08:00
Joe Beda d96afdd645 Move 'pkg/standalone' package to 'pkg/kubelet/server'. 
This paves the way to hyperkube for the kubelet.

Tim Hockin 6cb275829f Implement volumes as plugins. 
Break up the monolithic volumes code in kubelet into very small individual
modules with a well-defined interface.  Move them all into their own packages
and beef up testing along the way.

Eric Tune b759f67ee3 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.

Clayton Coleman ba53d723d3 Clean up how client is passed to Kubelet in preparation for reading pods 
Also fixes how Kubelet server looks up pods by name when there are multiple
sources.

Dawn Chen f718957a79 Move GetHostName and GetDockerEndpoint methods to pkg/util 2015-01-05 11:44:21 -08:00
Tim Hockin 652479a3b1 Add kubelet DNS flags & api disable for DNS 
This adds --cluster_dns and --cluster_domain flags to kubelet.  If
non-empty, kubelet will set docker --dns and --dns-search flags based on
these.  It uses the cluster DNS and appends the hosts's DNS servers.
Likewise for DNS search domains.

This also adds API support to bypass cluster DNS entirely, needed to
bootstrap DNS.

Eric Paris 630acf221c alias cadvisor/client to cadvisor 
cadvisor 0.5.0 changes the package from cadvisor to client.  Which of
course conflicts with our own client.  Alias it back to cadvisor.

Clayton Coleman 6881db64a9 Allow configurable Kubelet net image for isolated networks 
Public access to the DockerHub is not guaranteed in all environments,
add a flag to the kubelet that allows it to use a different image (like
one on a private registry) as well as only pull the first time the
image is needed.

Fixes #1545
