Instead of dynamically defaulting NodeRegistration.ImagePullPolicy,
which is common when doing defaulting depending on host state - e.g.
hostname, statically default it in v1beta3/defaults.go.
- Remove defaulting in checks.go
- Add one more unit test in checks_test.go
- Adapt v1beta2 conversion and fuzzer / round tripping tests
This also results in the default being visible when calling:
"kubeadm config print ...".
Given bootstraptoken/v1 is now a separate GV, there is no need
to duplicate the API and utilities inside v1beta3 and the internal
version.
v1beta2 must continue to use its internal copy due, since output/v1alpha1
embeds the v1beta2.BootstrapToken object. See issue 2427 in k/kubeadm.
- Make v1beta3 use bootstraptoken/v1 instead of local copies
- Make the internal API use bootstraptoken/v1
- Update validation, /cmd, /util and other packages
- Update v1beta2 conversion
Package bootstraptoken contains an API and utilities wrapping the
"bootstrap.kubernetes.io/token" Secret type to ease its usage in kubeadm.
The API is released as v1, since these utilities have been part of a
GA workflow for 10+ releases.
The "bootstrap.kubernetes.io/token" Secret type is also GA.
Add {Init|Join}Configuration.Patches, which is a structure that
contains patch related options. Currently it only has the "Directory"
field which is the same option as the existing --experimental-patches
flag.
The flags --[experimental-]patches value override this value
if both a flag and config is passed during "init" or "join".
The feature of "patches" in kubeadm has been in Alpha for a few
releases. It has not received major bug reports from users.
Deprecate the --experimental-patches flag and add --patches.
Both flags are allowed to be mixed with --config.
- Add the field SkipPhases in the public v1beta3 as a []string (omitempty)
- Add the field in the internal type
- Run generators
- Adapt v1beta2 converter for JoinConfiguration
- Remove the object form v1beta3 and internal type
- Deprecate a couple of phases that were specifically designed / named to
modify the ClusterStatus object
- Adapt logic around annotation vs ClusterStatus retrieval
- Update unit tests
- Run generators
Kubeadm no longer supports kube-dns and CoreDNS is the only
supported DNS server. Remove ClusterConfiguration.DNS.Type
from v1beta3 that is used to set the DNS server type.
- Pin the ClusterConfiguration when fuzzing
the internal InitConfiguration that embeds it. Kubeadm includes
separate constructs for this embedding in the internal type
and this round trip is not viable.
- Remove the artificial calls to SetDefaults_ClusterConfiguration()
in v1beta{2|3}'s converters from public to internal InitConfiguration.
- Make sure the internal InitConfiguration.ClusterConfiguration is
defaulted in initconfiguration.go instead.
- scheme: switch to:
utilruntime.Must(scheme.SetVersionPriority(v1beta3.SchemeGroupVersion))
- change all imports in the code base from v1beta2 to v1beta3
- rename all import aliases for kubeadmapiv1beta2 to "kubeadmapiv".
this allows smaller diffs when changing the default public API.
The v1beta1/2 API doc.go files include an example
flag for the kubelet binary "cgroup-driver" under
"kubeletExtraArgs".
This flag is deprecated and should not be in the examples.
Add "v" instead which is one of the flags we know will
not be deprecated soon.
