Problem on yum module on CentOS 7

[zorg...@gmail.com]

Hello,

I'm testing Ansible (version 1.7.1-1) on CentOS 7. Installation is minimalist then I need to install additional packages. Here is the playbook:

---
-
    hosts: localhost
    remote_user: root
    tasks:
        - name: install mandatory package list
          yum: name={{ item }}, state=present
          with_items:
              - bc
...

Ansible raises an error:

failed: [localhost] => (item=bc) => {"changed": true, "failed": true, "item": "bc", "rc": 0, "results": ["Loaded plugins: changelog, fastestmirror, kernel-module, protectbase, tsflags,\n              : versionlock\nLoading mirror speeds from cached hostfile\n54 packages excluded due to repository protections\nResolving Dependencies\n--> Running transaction check\n---> Package bc.x86_64 0:1.06.95-13.el7 will be installed\n--> Finished Dependency Resolution\nBeginning Kernel Module Plugin\nFinished Kernel Module Plugin\n\nDependencies Resolved\n\n================================================================================\n Package      Arch             Version                     Repository      Size\n================================================================================\nInstalling:\n bc           x86_64           1.06.95-13.el7              base           115 k\n\nTransaction Summary\n================================================================================\nInstall  1 Package\n\nTotal download size: 115 k\nInstalled size: 215 k\nDownloading packages:\nRunning transaction check\nRunning transaction test\nTransaction test succeeded\nRunning transaction\n  Installing : bc-1.06.95-13.el7.x86_64                                     1/1 \n  Verifying  : bc-1.06.95-13.el7.x86_64                                     1/1 \n\nInstalled:\n  bc.x86_64 0:1.06.95-13.el7                                                    \n\nComplete!\n"]}
msg: No Package matching '' found available, installed or updated

FATAL: all hosts have already failed -- aborting

Yum has done it's job (bc is actually installed), but Ansible seems to want to install an additional package named '' (nothing), which is obviously not present. Is this a bug or did I miss something?

I think it's because of the comma behind the }}  ?

Yes, take out out the comma.

Thank you very much, without the comma it works perfectly.

However it was not the exact case, I simplified to extract just what was wrong. In fact I'm using a role and get the same error:

---
-
    hosts: localhost
    remote_user:

root
    roles:
        -   { role: installation, args: '{{ ansible_local.localhost.host_type }}', when: 'ansible_local.localhost.host_type is defined' }

I've just tried without commas, but Ansible complains about quotes just after the first missing comma. I tried quotes in various places but without any success. I suppose it's a syntax error again... Any idea?

Oops, I've finally found the error: it was deeper, in the task of the installation role:

-   name: install mandatory package list
    yum: name={{ item }}, state=

present
    with_items: packages

You see, in second line, there is a comma that should not be there! Removing it solves the difficulty. Thank you very much again!
