Execute

nicholas-fedor/watchtower · cmd/root.go:155

func Execute(log *zerolog.Logger) {
	proc := &process{log: log}
	rootCmd.PreRun = proc.preRun
	rootCmd.Run = proc.run

	err := rootCmd.Execute()
	if err != nil {
		// Prefer proc.log so post-SetupLogging errors use the configured format/level.
		proc.log.Fatal().Err(err).Msg("Failed to execute root command")
	}
}

// preRun prepares the environment and configuration before the main command execution begins.
//
// It processes command-line flag aliases, configures logging based on verbosity settings,
// expands secrets from files, maps Docker flags into the process environment, loads the
// immutable appconfig snapshot, initializes the Docker client and notification client, and
// handles early-exit paths (ephemeral self-update orchestrator and invalid old-container restarts).
