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.
The kubeadm documentation instructs users to set the container
runtime driver to "systemd", since kubeadm manages a kubelet via
the systemd init system. The kubelet default however is "cgroupfs".
For new clusters set the driver to "systemd" unless the user
is explicit about it. The same defaulting would not happen
during "upgrade".
the controller manager should validate the podSubnet against the node-mask
because if they are incorrect can cause the controller-manager to fail.
We don't need to calculate the node-cidr-masks, because those should
be provided by the user, if they are wrong we fail in validation.
