Deploying behind a gateway server

About deployment gateways

If you want to deploy your application in a DMZ, you should prepare a bastion server which enables you to connect to your DMZ. You should define a Deployment Gateway in your Cloud 66 account and specify the information of the bastion server, then you will be able to deploy your application in the DMZ.

How to deploy your application behind a gateway server

Gateway management is available through toolbelt .

First you need to define a gateway:

$ cx gateways add --name aws_bastion --address 1.1.1.1  --username ec2-user  --private-ip 2.2.2.2

In order to use this gateway for application deployment, you need to first specify it in the manifest:

production:
   	gateway:
   	    name: aws_bastion
   	    username: ec2-user

and then make it available before you start the deployment:

$ cx gateways open --name aws_bastion --key /tmp/gateway.pem --ttl 1h

Now you can start deploying your application.

After the deployment is finished you can invalidate the gateway or leave it until the TTL is over.

$ cx gateways close --name aws_bastion

Adding servers behind an on-premises gateway

You can add registered servers to Cloud 66 via an on-premises gateway server as long as:

1. The registered servers are on the same network as the gateway
2. You are deploying a Rails application

To add a server behind your gateway:

1. SSH to the server and run the registered server registration script with the --header X-Fixed-IP:123.123.123.123 option - where X-Fixed-IP is set to the IP address that the gateway will use to access the server (usually the private IP address of the server).
2. Set up the gateway server and configure your application to use it via the manifest as specified above
3. Open the gateway and add the newly registered server to your application. Because the application is configured to use the gateway, it will go through the gateway and then direct requests to the IP address under X-Fixed-IP.

Accessing your servers behind the gateway server

If you want to connect to your servers behind the bastion server firstly you will need to have access to the bastion server's key, then you can use toolbelt to connect to your server:

$ cx ssh --gateway-key ~/.ssh/bastion_key  -s "My Awesome App" Lion
