Pass down into the server initialization the necessary interface for
handling client/server content type negotiation. Add integration tests
for the negotiation.
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.
A NegotiatedSerializer is passed into the API installer (and
ParameterCodec, which abstracts conversion of query params) that can be
used to negotiate client/server request/response serialization. All
error paths are now negotiation aware, and are at least minimally
version aware.
Watch is specially coded to only allow application/json - a follow up
change will convert it to use negotiation.
Ensure the swagger scheme will include supported serializations - this
now includes application/yaml as a negotiated option.
Add a recognizer that is capable of sniffing content type from data by
asking each serializer to try to decode - this is for a "universal
decoder/deserializer" which can be used by client logic.
Add codec factory, which provides the core primitives for content type
negotiation. Codec factories depend only on schemes, serializers, and
groupversion pairs.
Break Codec into two general purpose interfaces, Encoder and Decoder,
and move parameter codec responsibilities to ParameterCodec.
Make unversioned types explicit when registering - these types go
through conversion without modification.
Switch to use "__internal" instead of "" to represent the internal
version. Future commits will also add group defaulting (so that "" is
expanded internally into a known group version, and only cleared during
set).
For embedded types like runtime.Object -> runtime.RawExtension, put the
responsibility on the caller of Decode/Encode to handle transformation
into destination serialization. Future commits will expand RawExtension
and Unknown to accept a content encoding as well as bytes.
Make Unknown a bit more powerful and use it to carry unrecognized types.
If we don't use an elastic IP, the IP address will be lost if we lose
the master for any reason, and a replacement master will not have the
same IP. But the master IP is set both in client kubeconfig files and
the master SSL certificate. Hence the default should be to allocate an
elastic IP for the master.
One complication: AWS doesn't allow tags on elastic IPs, so it is hard
to track the elastic IP so we can delete it as part of kube-down.
Instead, we take the master EBS volume with the elastic IP. This is a
little odd, but works because the master volume & the master elastic IP
really need to be assigned to the same machine, so might be thought of
as a pair.
Also, we now delete the master EBS volume as part of kube-down, as
people expect kube-down to clean-up everything it creates.
It's currently unclear if the request failed because the proxy wasn't
quite up yet, or if it failed because traffic couldn't get from the
proxy to apiserver. Getting the proxy logs unconditionally should help
narrow this down.
This removes a panic I mistakenly introduced when an instance is not
found, and also restores the exact prior behaviour for
getInstanceByName, where it returns cloudprovider.InstanceNotFound when
the instance is not found.
Was marked as flaky prior to #11291, 6 months ago.
Code has changed many times.
No flakes in last 28 runs, and no Jenkins
history before that.
Follow up in #19024 if you see a flake.
