Unable to run Ansible for kubespray with a terraform modification. (AnsibleUndefinedVariable: 'ansible.vars.hostvars.HostVarsVars object)

Question

Hi Im tried to automate different type of node groups in terraform to dynamically populate the inventory file with the config of instance tags and configs we pass in custom tfvars.

I was able to render the inventory file properly, However when I run ansible command over it, it fails with

TASK [bastion-ssh-config : create ssh bastion conf] fatal: [bastion]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'ansible_host'"}

below is my custom generated inventory file

note: there is no change on ansible side as I believe the only link is the inventory file between terraform and ansible.

have tried with tag: 2.15

Where are you setting the `ansible_host` variable? Maybe you are trying to use `inventory_hostname`? Check the "magic variable" list here: https://docs.ansible.com/ansible/latest/reference_appendices/special_variables.html — cjnash, Mar 30 '21 at 15:57
