Would you mind inverting the two parts if this branch ? Putting the non-error case in the if part and the error case in the else part ? I think it makes it more readable because the default flow goes towards what we want to achieve. But maybe it is just me ? If you have good reasons to let it like that, let me know.

Sure, will do. I think this is more a go habit, as most of my if statements are used to check for the absence of errors 😄

// program termination. log.Fatal() exits with os.Exit(1).
log.WithLevel(zerolog.FatalLevel).Str("Port", urlPort).Err(err).Msg("cli contains an invalid port")
fmt.Fprintf(os.Stderr, "Bad port '%s'\n", urlPort)
return -1

Add the comment // no port specified in the CLI args ?

// There is no port in the CLI, but one in a config file. Use the config port.
port = configPort
} else {
// There is no port specified, neither in the CLI, nor in the configuration.

Add a comment, like // no explicit port from the CLI and no port specified in config ?
