Ansible, the field args has an invalid value
10,950
with_items: hosts
This is obsolete syntax. You can't use bare variables for loops.
Correct syntax: with_items: "{{ hosts }}"

I added a role called common to my playbook.yml, and provisioning fails with the message:
TASK [common : Host is present] ************************************************ ==> cd: fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'unicode object' has no attribute 'host_ip'\n\nThe error appears to have been in '/vagrant/ansible/roles/common/tasks/main.yml': line 7, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Host is present\n ^ here\n"}
here is the content of
roles/common/tasks/main.yml
, the particular tasks which fails- name: Host is present lineinfile: dest: /etc/hosts regexp: "^{{ item.host_ip }}" line: "{{ item.host_ip }} {{ item.host_name }}" with_items: hosts tags: [common]
And here is the content of
roles/common/defaults/main.yml
hosts: [ { host_ip: "10.100.198.200", host_name: "cd"}, { host_ip: "10.100.198.201", host_name: "prod"}, { host_ip: "10.100.198.202", host_name: "logging"}, { host_ip: "10.100.194.201", host_name: "serv-disc-01"}, { host_ip: "10.100.194.202", host_name: "serv-disc-02"}, { host_ip: "10.100.194.203", host_name: "serv-disc-03"}, { host_ip: "10.100.193.200", host_name: "proxy"}, { host_ip: "10.100.192.200", host_name: "swarm-master"}, { host_ip: "10.100.192.201", host_name: "swarm-node-1"}, { host_ip: "10.100.192.202", host_name: "swarm-node-2"}, ] obsolete_services: - puppet - chef-client
Why ansible claims that args is undefined. The example I'm using is not made by me and is few months old, so I wonder, if the way ansible processes variables in roles has changed, and thus it doesn't work.
