Getting template error while templating string: unexpected char while running a playbook with a role

[Jörg Kastning]

Good morning,

I'm getting the following Error when running my playbook:

TASK [patch_rhel : Install Red Hat Security Advisory (RHSA)] *******************
fatal: [rhel-t0.hrz.uni-bielefeld.de]: FAILED! => {"failed": true, "msg": "{{ 2016_1_Set }}: template error while templating string: unexpected char u'_' at 7. String: {{ 2016_1_Set }}"}

I would be very happy if someone could help me to figure out what I'm doing wrong here.

Here are some information about my environment:

[2016.10.11 09:06:25] /data/ansible
root@ansible-pctrl01>cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)
[2016.10.11 09:07:57] /data/ansible
root@ansible-pctrl01>uname -r
3.10.0-327.36.1.el7.x86_64
[2016.10.11 09:08:03] /data/ansible
root@ansible-pctrl01>ansible --version
ansible 2.1.1.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

The playbook I'm trying to run:

root@ansible-pctrl01>cat patch_rhel.yml
---
- hosts: all

  tasks:
    - name: Group by OS
      group_by: key=os_{{ ansible_distribution }}
      changed_when: False

- hosts: os_RedHat
  roles:
    - patch_rhel

Here is the directory structure of my role followed by the contents of the tasks and vars main.yml:

roles/patch_rhel/
|-- [joerg    4.0K]  tasks
|   `-- [joerg     662]  main.yml
`-- [joerg    4.0K]  vars
    `-- [joerg     270]  main.yml

# cat roles/patch_rhel/tasks/main.yml
---
  - name: Install Red Hat Security Advisory (RHSA)
    command: yum -y update-minimal --advisory {{ rhsa_to_install }}
    register: yum_output
  - debug: var=yum_output

  - name: Reboot Host if packages were updated
    shell: sleep 2 && shutdown -r now "Ansible updates triggered"
    async: 1
    poll: 0
    ignore_errors: true
    when: ('"Complete!" in "{{ yum_output.stdout_lines[-1] }}"') or
          ('"Komplett!" in "{{ yum_output.stdout_lines[-1] }}"')

  - name: waiting for access server
    local_action: wait_for
      host={{ inventory_hostname }}
      state=started
      port=22
      delay=30
      timeout=300
      connect_timeout=15

# cat roles/patch_rhel/vars/main.yml
---
  2016_09_27: RHSA-2016:1940
  2016_09_28: RHSA-2016:1944
  2016_09_30: RHEA-2016:1982
  #
  2016_10_Set: "{{ 2016_09_27 }},{{ 2016_09_28 }},{{ 2016_09_30 }}"
  #
  rhsa_to_install: "{{ 2016_10_Set }}"

Things I tried so far were to remove the '_' but then I got the same error message complaining with the next character in line. Removing the character right before the one mentioned in the error I'm running into the same error as well.

To get my playbook up and running I changed roles/patch_rhel/vars/mail.yml to:

cat roles/patch_rhel/vars/main.yml
---
  2016_09_27: RHSA-2016:1940
  2016_09_28: RHSA-2016:1944
  2016_09_30: RHEA-2016:1982
  #
  #2016_10_Set: "{{ 2016_09_27 }},{{ 2016_09_28 }},{{ 2016_09_30 }}"
  #
  #rhsa_to_install: "{{ 2016_10_Set }}"
  rhsa_to_install: RHSA-2016:1940,RHSA-2016:1944,RHEA-2016:1982

Now my playbook runs without any failures. But I like to use the first version to be more flexible in applying my advisory.

Thank you in advance for your ideas and support on this. Looking forwared to reading from you.

Regards,
Joerg

Oh Boy, I'm such a fool. Variable names must not begin with a digit. Instead they need to begin with a character.

After this mistake was fixed my playbook runs as expected.

Mit freundlichen Grüßen
