Generate yaml file using Ansible playbook

Infrastructure as Code Ansible
#1

I was working on creating a YAML file with the below details using the Ansible playbook —

tasks:

  • name: “add content into cluster.yaml file”
    ansible.builtin.blockinfile:
    path: /home/ansible/ansible_rancher_k8s_installation/cluster.yaml
    block: |

    if you intended to deploy Kubernetes in an air-gapped environment,

    please consult the documentation on how to configure custom RKE images.

    nodes:
    • address:
      internal_address: “”
      role:
      • controlplane
      • etcd
      • worker
        user: rke

but I am getting an error as below —

[ansible@ansible-controller playbooks]$ ansible-playbook ./01-create-rke-k8s-cluster.yaml --check
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match ‘all’
