Deis paas on Google Cloud don't understand a command

Question

I'm deploying Deis Paas on Google Cloud. In the official provisioning guide available at http://docs.deis.io/en/latest/installing_deis/install-platform/ there are a few commands.

I don't understand on which domain this command refers

deisctl config platform set domain=example.com

what should I put instead of "example.com"?

Are you following these docs? http://docs.deis.io/en/latest/installing_deis/gce/#deis-on-gce

If so then the domain will be your/company domain.

Once you have this in your configs, you can create subdomains from DEIS CLI itself which can also be written in config files. This helps automating the provisioning of subdomains and if need be during scaling using dynamic provisioning.

More details:

• When you are looking at a solution which can do automatic deployments, that means that not only that solution will deploy an instance with your application code in it, but also that it will configure the network, proxy or configuring access to databases etc.
• One of these processes is to configure a subdomain for your application. You could be running your website on domain.com and your webapp on web.domain.com, while your database can be running on db.domain.com.
• This is easily configurable manually, but in most cases when you deploy a new instance, the IP for that instance is randomly selected from a pool of IPs. Hence its rare that you will get the same IP again on next deployment. NOTE: We are not talking about deploying app on a VM, but deploying a new VM altogether with updated application code.
• Similar cases arise when you want to do auto-scaling during load balancing or a alpha release which will auto-upgrade releases on all the instances.
• For all such cases either you can set the CNAME and A Records manually or you can let DEIS do it for you.
• In order for DEIS (or similar solutions) to do it, you need to verify your domain name (or at-least configure). Once this domain name is in global configurations, everytime you launch a newer version of your web-app, DEIS can put it in a instance and point it at v1-web.domain.com.
• Once its verified that deployment was successful and its serving, it can now be auto-upgraded to web.domain.com. All this happening based on the rules that you specify in configurations of you application.

Hope this is enough. If not you should read more about how Google App-Engine works, or rather give it a try.
