Brendan Burns e84b4d03a4 Merge pull request #3183 from anguslees/pull-lock 
Avoid race between image pull and garbage collect
 2015-01-06 21:23:29 -08:00

Angus Lees 6f14e2e210 Avoid race between image pull and garbage collect 
Hold the pullLock while pulling regular container images, not just the
network container.

Also: previously, the locks were grabbed at too-low a layer in the
callstack, leaving a (narrow) window where images could be pulled and
then garbage collected before being used.

This change takes the existing pullLock a layer higher in the call stack
so the critical regions encompass the entire find+delete and pull+use
operation in both cases.

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.

Clayton Coleman 892942af8f Read BoundPods from etcd instead of ContainerManifestList 
There are three values that uniquely identify a pod on a host -
the configuration source (etcd, file, http), the pod name, and the
pod namespace. This change ensures that configuration properly
makes those names unique by changing podFullName to contain both
name (currently ID in v1beta1, Name in v1beta3) and namespace.

The Kubelet does not properly handle information requests for
pods not in the default namespace at this time.

image is needed.

Clayton Coleman 4e56dafecc Introduce some default log verbosity control 
Move a lot of common error logging into better buckets:

glog.Errorf() - Always an error
glog.Warningf() - Something unexpected, but probably not an error
glog.V(0) - Generally useful for this to ALWAYS be visible
            to an operator
            * Programmer errors
            * Logging extra info about a panic
            * CLI argument handling
glog.V(1) - A reasonable default log level if you don't want
            verbosity
            * Information about config (listening on X, watching Y)
            * Errors that repeat frequently that relate to conditions
              that can be corrected (pod detected as unhealthy)
glog.V(2) - Useful steady state information about the service
            * Logging HTTP requests and their exit code
            * System state changing (killing pod)
            * Controller state change events (starting pods)
            * Scheduler log messages
glog.V(3) - Extended information about changes
            * More info about system state changes
glog.V(4) - Debug level verbosity (for now)
            * Logging in particularly thorny parts of code where
              you may want to come back later and check it

Francisco Souza 2a345ffa9e third_party: update go-dockerclient 
math.MaxInt64 represents 8 exabytes, which is a good limit for memory.
Also, this is the type used by Docker, so it's not possible to get any
value bigger than math.MaxInt64 as memory limit (both ram and swap) on a
Docker container.

Victor Marmol b131da1cf5 Sync pods asynchronously in the Kubelet. 
This makes two main changes:
- Runs syncPod in a separate Go routine (and enforces only one of those
  runs at a time).
- Uses the pod list to determine if a container should be running or
  should be killed (used to use the output of syncPod).

Since Docker pulls are synchronized by the Docker daemon we still block
on that, but pods can now be removed and prepared for starting without
blocking on long pulls.

apiserver by passing rawquery.

minor changes

Victor Marmol 88317efb42 Add a pause image for the net container. 
The pause image is a 240KB image that simply pauses waiting on a signal.
Use this for the net container which only needs to act as a placeholder.
Current net image is ~2.5MB. From my tests, this reduces startup time
for the net container from ~14s to ~6s.

Kelsey Hightower dc7ee7c333 normalize -etcd_servers flag across all commands 
The -etcd_servers flag is used inconsistently by the Kubernetes commands,
both externally and internally.

This patch fixes the issue by using the same type to represent a list of
etcd servers internally, and declares the -etcd_servers flag consistently
across all commands.

This patch should be 100% backwards compatible with no changes in behavior.

 2014-06-24 22:05:25 -07:00
Tim Hockin 9f9e75f508 Switch to glog for logging, bridge logging to glog. 
1) imported glog to third_party (previous commit)
2) add support for third_party/update.sh to update just one pkg
3) search-and-replace:
  s/log.Printf/glog.Infof/
  s/log.Print/glog.Info/
  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.
