I'm simply trying to check the version of ubuntu on all my servers. Based on this question I see that ansible has a ansible_distribution_version but this playbook does not show how I would simply just have it print out the ubuntu version, ie ubuntu 14.04, 16.04, etc

You can do one at the time
--- - hosts: localhost gather_facts: yes become: false tasks: - name: Distribution debug: msg="{{ ansible_distribution }}" - name: Distribution version debug: msg="{{ ansible_distribution_version}}" - name: Distribution major version debug: msg="{{ ansible_distribution_major_version }}" See the results:
PLAY [localhost] *********************************************************************************************************************************************************** TASK [Gathering Facts] ***************************************************************************************************************************************************** ok: [localhost] TASK [Distribution] ******************************************************************************************************************************************************** ok: [localhost] => { "msg": "Ubuntu" } TASK [Distribution version] ************************************************************************************************************************************************ ok: [localhost] => { "msg": "18.04" } TASK [Distribution major version] ****************************************************************************************************************************************** ok: [localhost] => { "msg": "18" } PLAY RECAP ***************************************************************************************************************************************************************** localhost : ok=4 changed=0 unreachable=0 failed=0 Or you can use a more advance configuration iterating facts:
- hosts: localhost gather_facts: yes become: false tasks: - name: System details debug: msg="{{ item }}" with_items: - "{{ ansible_distribution }}" - "{{ ansible_distribution_version }}" - "{{ ansible_distribution_major_version }}" And a more compact results:
PLAY [localhost] *********************************************************************************************************************************************************** TASK [Gathering Facts] ***************************************************************************************************************************************************** ok: [localhost] TASK [System details] ****************************************************************************************************************************************************** ok: [localhost] => (item=Ubuntu) => { "msg": "Ubuntu" } ok: [localhost] => (item=18.04) => { "msg": "18.04" } ok: [localhost] => (item=18) => { "msg": "18" } PLAY RECAP ***************************************************************************************************************************************************************** localhost : ok=2 changed=0 unreachable=0 failed=0 In both cases is a good practices to get the info using facts instead of shell or command modules.
I got it, to check the OS version here is the playbook
--- - hosts: all gather_facts: False tasks: - name: Check Dist Version shell: cat /etc/os-release register: response - debug: msg="{{ response.stdout }}" After very research to find out Ubuntu 20.04 version then we have got released a version using ansible version-2.5.1
- hosts: localhost become: true gather_facts: yes tasks: - name: System details debug: msg: "{{ ansible_facts['lsb']['release'] }}" - name: ubuntu 18 shell: echo "hello 18" register: ub18 when: ansible_facts['lsb']['release'] == "18.04" - debug: msg: "{{ ub18 }}" - name: ubuntu 20 shell: echo "hello 20" register: ub20 when: ansible_facts['lsb']['release'] == "20.04" - debug: msg: "{{ ub20 }}"
