Provision aws hosts

Hi, I’m new to ansible and have confusion.
What I have right now:
ansible+vagrant playbook. Vagrant creates VMs in virtualbox and sets up networking.
Ansible does provisioning stuff:

  • install
  • configure
  • put some templates

Right now all host names and IP addresses are hardcoded.
Example for host variable used to configure software.
/host_vars/dsenode03

config:
cluster_name: ‘DSE Cluster’
seeds: ‘192.168.56.10’
listen_address: 192.168.56.10
rpc_address: 192.168.56.10

Really, I point dsenode03 to dsenode01 (92.168.56.10)

If I turn to AWS I can’t hardcode smth, since names,addresses would be different each time.
What is the right approach to remove hardcodes? Can I find some examples?

I think you want to look into using dynamic inventories.

Start with http://docs.ansible.com/intro_dynamic_inventory.html.
