Migrate to the new conversion generator - part1
This PR contains two commits:
- few more fixes to the generator
- migration of the pkg/api/v1 to use the new generator
The second commit is big, but I reviewed the changes and they contain:
- conversions between types that we didn't even generating conversion between
- changes in how we handle maps/pointers/slices - previously we were explicitly referencing fields, now we are using "shadowing in, out" to make the code more generic
- lack of auto-generated method for ReplicationControllerSpec (because these types are different (*int vs int for Replicas) and a preexisting conversion already exists
Most of issues in the first commit (e.g. adding references to "in" and "out" for slices/maps/points) were discovered by our tests. So I'm pretty confident that this change is correct now.
Most volume plugins use SafeFormatAndMount, which uses ext4 by default.
FlexVolume plugin has FSType attribute 'omitempty', so reflect it in the
description of the type.
Remove Codec from versionInterfaces in meta (RESTMapper is now agnostic
to codec and serialization). Register api/latest.Codecs as the codec
factory and use latest.Codecs.LegacyCodec(version) as an equvialent to
the previous codec.
Enforce minimum resource granularity of milli-{core, bytes} for Storage,
Memory, and CPU resource types. For Storage and Memory, milli-bytes are
allowed for backwards compatability, but the behavior is
undefinied (depends on docker implementation).
1. Name default scheduler with name `kube-scheduler`
2. The default scheduler only schedules the pods meeting the following condition:
- the pod has no annotation "scheduler.alpha.kubernetes.io/name: <scheduler-name>"
- the pod has annotation "scheduler.alpha.kubernetes.io/name: kube-scheduler"
update gofmt
update according to @david's review
run hack/test-integration.sh, hack/test-go.sh and local e2e.test
This enables use of software or hardware transports viz. be2iscsi,
bnx2i, cxgb3i, cxgb4i, qla4xx, iser and ocs. The default transport
(tcp) happens to be called "default".
Use of non-default transports changes the disk path to the following format:
/dev/disk/by-path/pci-<pci_id>-ip-<portal>-iscsi-<iqn>-lun-<lun_id>
Before this change we have a mish-mash of ways to pass field names around for
error generation. Sometimes string fieldnames, sometimes .Prefix(), sometimes
neither, often wrong names or not indexed when it should be.
Instead of that mess, this is part one of a couple of commits that will make it
more strongly typed and hopefully encourage correct behavior. At least you
will have to think about field names, which is better than nothing.
It turned out to be really hard to do this incrementally.
All external types that are not int64 are now marked as int32,
including
IntOrString. Prober is now int32 (43 years should be enough of an initial
probe time for anyone).
Did not change the metadata fields for now.
- PeriodSeconds - How often to probe
- SuccessThreshold - Number of successful probes to go from failure to success state
- FailureThreshold - Number of failing probes to go from success to failure state
This commit includes to changes in behavior:
1. InitialDelaySeconds now defaults to 10 seconds, rather than the
kubelet sync interval (although that also defaults to 10 seconds).
2. Prober only retries on probe error, not failure. To compensate, the
default FailureThreshold is set to the maxRetries, 3.
The functions would default values added after v1.0, so that kubelet wouldn't
fail at comparing the mirror pods against their associated static pods.
This code would need to be maintained if we ever change the default value in
Pod until we drop support for v1.0 nodes.
Define a new out of disk node condition and use it to report when node
goes out of disk.
Make a copy of loop range clause variable in node listers so that it
is available outside the for loop.
Also update/implement unit tests.
Flocker [1] is an open-source container data volume manager for
Dockerized applications.
This PR adds a volume plugin for Flocker.
The plugin interfaces the Flocker Control Service REST API [2] to
attachment attach the volume to the pod.
Each kubelet host should run Flocker agents (Container Agent and Dataset
Agent).
The kubelet will also require environment variables that contain the
host and port of the Flocker Control Service. (see Flocker architecture
[3] for more).
- `FLOCKER_CONTROL_SERVICE_HOST`
- `FLOCKER_CONTROL_SERVICE_PORT`
The contribution introduces a new 'flocker' volume type to the API with
fields:
- `datasetName`: which indicates the name of the dataset in Flocker
added to metadata;
- `size`: a human-readable number that indicates the maximum size of the
requested dataset.

Rather than an "all or nothing" approach to defining a custom conversion
function (which seems destined to cause problems eventually), this is an
attempt to make it possible to call the auto-generated code and then "fix it
up".
Specifically, consider you have a fooBar struct. If you don't define a
conversion for FooBar, you will get a generated function like:
convert_v1_FooBar_To_api_FooBar()
Before this PR, if you define your own conversion function, you get no
generated function. After this PR you get:
autoconvert_v1_FooBar_To_api_FooBar()
...which you can call yourself in your custom function.
Increase the supported controls on pod logging. Add validaiton to pod
log options. Ensure the Kubelet is using a consistent, structured way to
process pod log arguments.
Add ?sinceSeconds=<durationInSeconds>, &sinceTime=<RFC3339>, ?timestamps=<bool>,
?tailLines=<number>, and ?limitBytes=<number>
Add a HostIPC field to the Pod Spec to create containers sharing
the same ipc of the host.
This feature must be explicitly enabled in apiserver using the
option host-ipc-sources.
