I am writing a rolling upgrade playbook and would like to print out the hostname of current host been upgraded.

I put inventory_hostname and ansible_hostname in task names but that did not work

- name: upgrade softare on {{inventory_hostname}}
- name: current host is {{ansible_hostname}}

debug works fine

- name: Test a variable
  debug: var=inventory_hostname

TASK: [Test a variable] ******************************************************* 
ok: [SERV14] => {
    "var": {
        "inventory_hostname": "SERV14"

So what should I do to be able to use those variables in task name descriptions.

    Currently, variable substitution can not be done in name. See here – cuonglm May 8 '15 at 7:39

Starting from v2.0 Ansible supports variable substitution in task/handler names: https://github.com/ansible/ansible/issues/10347, so these examples will work as expected:

- name: upgrade software on {{inventory_hostname}}
- name: current host is {{ansible_hostname}}

I think bro you should write the {{ ansible_hostname }} after the tasks: , because before that it doesn't gathered facts so it didn't give the result .(I may be wrong in the concept but practical was successful)


  • name: Install the httpd on {{ ansible_hostname }} (here . means -)


    name: httpd 
    state: latest
