I have a problem with installation Discourse on ec2 AWS instance ubuntu 18.04.  
I took [ami-22741f5a](https://console.aws.amazon.com/ec2/home?region=us-west-2#launchAmi=ami-22741f5a) from [Ubuntu Amazon EC2 AMI Finder](https://cloud-images.ubuntu.com/locator/ec2/).  
installed docker `sudo apt-get install docker.io`

```bash
docker version
Client:
 Version:	17.12.1-ce
 API version:	1.35
 Go version:	go1.10.1
 Git commit:	7390fc6
 Built:	Wed Apr 18 01:23:11 2018
 OS/Arch:	linux/amd64

Server:
 Engine:
  Version:	17.12.1-ce
  API version:	1.35 (minimum version 1.12)
  Go version:	go1.10.1
  Git commit:	7390fc6
  Built:	Wed Feb 28 17:46:05 2018
  OS/Arch:	linux/amd64
  Experimental:	false

```

when I tried to run `./launcher bootstrap app` I got

```plaintext
cd /pups && git pull && /pups/bin/pups --stdin
fatal: unable to access 'https://github.com/SamSaffron/pups.git/': Could not resolve host: github.com
fd2db3f069b7e4acf63e853409143403956ad61fd0d5bff9daaed96955af1f67
**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one.

```

Also I installed ubuntu 18.04 on virtualbox manually and didn’t see this problem.  
Could you help me?  
thank you in advance
