Class Method Details

.run(ui, command, chdir: nil, tolerate: nil, tolerate_message: nil) ⇒ Object

tolerate: optional Regexp. When the command fails but its stderr matches it, the failure is treated as a benign no-op (e.g. kubectl wait finding no matching resources) — logged as detail instead of raising. tolerate_message: friendly text to log in that case instead of echoing the raw (and alarming) stderr.
