Automatic DNS Configuration

It can be annoying to configure DNS manually on each launched instance. (Otherwise it is not possible to download essential linux tools) Therefore, it is recommended to (additionally to the Cheatsheet) edit the network settings.

  1. Edit Subnet
  2. Go to Subnet details
  3. Add the IP of publicly available DNS nameservers
