[Verse 1]
When a node is cordoned off, no pods can land
It's marked as unschedulable across the cluster span
Maintenance is done, the hardware's running clean
Time to bring it back into the scheduling scene
[Chorus]
Uncordon, uncordon, let the workloads flow
kubectl uncordon, watch the green light glow
Node name in the command, scheduling's back again
Uncordon, uncordon, pods can run my friend
[Verse 2]
Maybe you were patching or fixing something broke
Cordoned for safety, now remove that scheduling yoke
The node sits ready with resources to spare
But scheduling's blocked until you declare
[Chorus]
Uncordon, uncordon, let the workloads flow
kubectl uncordon, watch the green light glow
Node name in the command, scheduling's back again
Uncordon, uncordon, pods can run my friend
[Bridge]
Type the command line, specify the node
kubectl uncordon removes the scheduling load
From blocked to ready, the status will change
Pods can be placed in the cluster range
[Verse 3]
Check your node status before and after too
See the Ready state when the uncordon's through
No more unschedulable taint upon the node
Back in rotation for the workload load
[Chorus]
Uncordon, uncordon, let the workloads flow
kubectl uncordon, watch the green light glow
Node name in the command, scheduling's back again
Uncordon, uncordon, pods can run my friend
[Outro]
When maintenance ends and you're ready to go
Uncordon that node and watch the traffic flow
