kubectl upgrade

The conductor for any Kubernetes upgrade

Upgrading Kubernetes is the scariest routine operation in the job. kubectl upgrade turns it into a conducted process: pre-flight checks catch version-skew and addon incompatibilities before you start, the run phase executes the upgrade, watch mode streams progress, unstick helps when nodes wedge, and verify confirms the cluster is healthy after. Works across single clusters and fleets. Installs as a standard kubectl plugin, no krew required.

Why it exists

• ✓Pre-flight: version skew, addon compatibility, PDB and drain checks
• ✓Conducted upgrade flow: run, watch, unstick, verify
• ✓Fleet mode for many clusters
• ✓Standard kubectl plugin, auto-discovered, no krew needed
