Set the example values for your environment; related explanations and copy panels update together. Never enter passwords, private keys or tokens. Values stay in this tab and are not sent to the server or share links. Check actual DNS, certificates and network policy before running commands.
Different IP addresses, domains or ports? Open the settings below, change the values and select “Apply to tutorial”, then copy the updated commands.

Keep evidence that survives a green status
Record the selected context, namespace, old/new Pod UID, image identity, termination reason/time, relevant redacted logs, corrected hypothesis and observation window. Define a recurrence signal using restart rate plus application availability. Documentation review is the authoring evidence here; no cluster was deliberately crashed and no installation matrix or production recovery is claimed.
