I have a non-default vpc where i want to launch instances. The docs http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-vpc.html say:
Non-default vpc: "DNS hostnames are disabled by default."
Currently there is no option to set in during ec2-launch with "aws ec2 run-instances".
http://docs.aws.amazon.com/cli/latest/reference/ec2/run-instances.html
Any idea?

In this example, both DNS hostnames and DNS resolution are enabled. To update these settings, choose Actions and then choose Edit VPC settings. Select or clear Enable on the appropriate DNS attribute and choose Save changes.
To set up DNS in your VPC, ensure that DNS hostnames and DNS resolution are both enabled in your VPC. The VPC network attributes enableDnsHostnames and enableDnsSupport must be set to true . To view and modify these attributes, go to the VPC console at https://console.aws.amazon.com/vpc/ .
To enable DNS resolution and DNS hostnames for your VPC, open the VPC Management Console > Your VPCs. Click on your VPC and then click on Actions and then enable both Edit DNS Resolution & Edit DNS Hostnames.
