Errors when executing - ansible -m ping all - kubespray

Question

I'm trying to provision my kubernetes cluster using kubespray, when I try to execute this command:

$ ansible -m ping all

It gives me these warnings intead of the expected output.

 [WARNING]:  * Failed to parse /etc/ansible/hosts with yaml plugin: YAML

inventory has invalid structure, it should be a dictionary, got: <class

'ansible.parsing.yaml.objects.AnsibleUnicode'>

 [WARNING]:  * Failed to parse /etc/ansible/hosts with ini plugin:

/etc/ansible/hosts:45: Expected key=value host variable assignment, got:

192.168.56.101

 [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source

 [WARNING]: No inventory was parsed, only implicit localhost is available

 [WARNING]: provided hosts list is empty, only localhost is available. Note

that the implicit localhost does not match 'all'

Hey @Ananya, make sure of these following things:

configured your hosts by adding the hosts in /etc/ansible/hosts file

made the ssh connection 

Comments

I have done both of them and I still get the error

---

Also make sure the hosts are present in /etc/hosts file

---

Yes its present in this format

server <server-ip>

host <host-ip>

---

Ahhhh that's where you're going wrong.

Add only the host name without the ip and there is no need to add the server ip. Those should be added in your /etc/ansible/hosts

---

That was great, warnings are gone. Thanks
