This refactor removes the legacy KubeletConfig object and adds a new
KubeletDeps object, which contains injected runtime objects and
separates them from static config. It also reduces NewMainKubelet to two
arguments: a KubeletConfiguration and a KubeletDeps.
Some mesos and kubemark code was affected by this change, and has been
modified accordingly.
And a few final notes:
KubeletDeps:
KubeletDeps will be a temporary bin for things we might consider
"injected dependencies", until we have a better dependency injection
story for the Kubelet. We will have to discuss this eventually.
RunOnce:
We will likely not pull new KubeletConfiguration from the API server
when in runonce mode, so it doesn't make sense to make this something
that can be configured centrally. We will leave it as a flag-only option
for now. Additionally, it is increasingly looking like nobody actually uses the
Kubelet's runonce mode anymore, so it may be a candidate for deprecation
and removal.
Move SystemReserved and KubeReserved into KubeletConfiguration struct
Convert int64 to int32 for some external type fields so they match internal ones
tLS* to tls* for JSON field names
Fix dependency on removed options.AutoDetectCloudProvider
Change floats in KubeletConfiguration API to ints
Automatic merge from submit-queue
Generates DELETE pod update operations
fixes#27105
Generates DELETE pod update operations to make the code and log more intuitive.
1. main refactoring is in `kubelet/config`
2. kubelet will log if it received DELETE, just like other OPs

`--kubelet-cgroups` and `--system-cgroups` respectively.
Updated `--runtime-container` to `--runtime-cgroups`.
Cleaned up most of the kubelet code that consumes these flags to match
the flag name changes.

This is part of migrating kubelet configuration to the componentconfig api
group and is preliminary to retrofitting client configuration and
implementing full fledged API group mechinary.

- add busybox static pod to mesos-docker cluster
- customize static pods with binding annotations
- code cleanup
- removed hacky podtask.And func; support minimal resources for static pods when resource accounting is disabled
- removed zip archive of static pods, changed to gzip of PodList json
- pod utilities moved to package podutil
- added e2e test
- merge watched mirror pods into the mesos pod config stream
This patch reduces the dependencies of the executor from the kubelet. This
makes it possible launch the kubelet after the executor.
This considerably reduces the complexity of the startup code.
Moreover, this work is a requirement to use a standalone kubelet some day.
