Additional Ref# #105963 (comment)
Signed-off-by: Humble Chirammal <hchiramm@redhat.com>
- During "upgrade apply" call a new function AddNewControlPlaneTaint()
that finds all nodes with the new "control-plane" node-role label
and adds the new "control-plane" taint to them.
- The function is called in "apply" and is separate from
the step to remove the old "master" label for better debugging
if errors occur.
- Apply "control-plane" taint during init/join by adding the
taint in SetNodeRegistrationDynamicDefaults(). The old
taint "master" is still applied.
- Clarify API docs (v1beta2 and v1beta3) for nodeRegistration.Taint
to not mention "master" taint and be more generic. Remove
example for taints that includes the word "master".
- Update unit tests.
- Update the markcontrolplane phase used by init and join to
only label the nodes with the new control plane label.
- Cleanup TODOs about the old label.
- Remove outdated comment about selfhosting in staticpod/utils.go.
Selfhosting has not been supported in kubeadm for a while
and the comment also mentions the "master" label.
- Update unit tests.
- Rename the function in postupgrade.go to better reflect
what is being done.
- During "upgrade apply" find all nodes with the old label
and remove it by calling PatchNode.
- Update health check for CP nodes to not track "master"
labeled nodes. At this point all CP nodes should have
"control-plane" and we can use that selector only.
- Throw an error if there is more than one known socket on the host.
- Remove the special handling for docker+containerd.
- Remove the local instances of constants for endpoints for
Windows / Unix and use the defaultKnownCRISockets variable
which is populated from OS specific constants.
- Update error message in detectCRISocketImpl to have more
details.
- Make detectCRISocketImpl accept a list of "known" sockets
- Update unit tests for detectCRISocketImpl and make them
use generic paths such as "unix:///foo/bar.sock".
Change the default container runtime CRI socket endpoint to the
one of containerd. Previously it was the one for Docker
- Rename constants.DefaultDockerCRISocket to DefaultCRISocket
- Make the constants files include the endpoints for all supported
container runtimes for Unix/Windows.
- Update unit tests related to docker runtime testing.
- In kubelet/flags.go hardcode the legacy docker socket as a check
to allow kubeadm 1.24 to run against kubelet 1.23 if the user
explicitly sets the criSocket field to "npipe:////./pipe/dockershim"
on Windows or "unix:///var/run/dockershim.sock" on Linux.
In the following code pattern, the log message will get logged with v=0 in JSON
output although conceptually it has a higher verbosity:
if klog.V(5).Enabled() {
klog.Info("hello world")
}
Having the actual verbosity in the JSON output is relevant, for example for
filtering out only the important info messages. The solution is to use
klog.V(5).Info or something similar.
Whether the outer if is necessary at all depends on how complex the parameters
are. The return value of klog.V can be captured in a variable and be used
multiple times to avoid the overhead for that function call and to avoid
repeating the verbosity level.
