GCloud Interactive Shell

If you already have Google SDK installed, you can activate GCloud Interactive Shell, which is still in beta by the way, by typing the following command from the Google SDK terminal.

gcloud beta interactive

The interactive shell environment has auto-completion. It shows you who’s logged in and which project you are currently set in. To exit the interactive shell, just Press F9 to quit.

CodeIgniter Base URL

I have a CodeIgniter dev site in Google Cloud. The instance obtains a new IP address at every start. You can set the base URL to a domain or IP address in the “/application/config/config.php” file. Since it’s only a dev box, I don’t have a domain assigned. It’s accessible via IP address only which changes every time the instance is started. So here’s the workaround. I added some extra code in the config file to obtain the external IP address.

$realIP = file_get_contents("http://ipecho.net/plain");
$config['base_url'] = 'http://'.$realIP;

The code is using a service from ipecho.net which returns your external IP address. Works like a charm!
