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](http://docs.ansible.com/intro_dynamic_inventory.html).
