Re: [ansible-project] Comparing checksums on a group of files

The template and copy modules do this automatically, files are only
copied if different.

[ansible-project] Comparing checksums on a group of files

[Hank Beatty]

Hello,

I would like to compare checksums on a group of files and then copy the new 
file over the old file if different.

Here is what I have so far:

|- name: Get Checksum for Old Comparison Zone Files||
||  stat:||
||    path: "{{ named_options.directory }}/.{{ item.file }}.old"||
||  register: named_old_zones_stat||
||  with_items: "{{ named_zones | default([]) }}"||
||
||- debug:||
||    var: named_old_zones_stat||
||
||- name: Create New Comparison Zone Files||
||  template:||
||    src: zone_hidden.j2||
||    dest: "{{ named_options.directory }}/.{{ item.file }}.new"||
||  with_items: "{{ named_zones | default([]) }}"||
||
||- name: Get Checksum for New Comparison Zone Files||
||  stat:||
||    path: "{{ named_options.directory }}/.{{ item.file }}.new"||
||  register: named_new_zones_stat||
||  with_items: "{{ named_zones | default([]) }}"||
||
||- name: Copy the New Comparison Zones Over Old if Different||
||  template:||
||    src: zone_hidden.j2||
||    dest: "{{ named_options.directory }}/.{{ item.file }}.old"||
||  with_items: "{{ named_zones | default([]) }}"||
||  when: |

The last task is where I am stumbling. I was thinking of using "with_nested" in the last task, but I cannot seem to make 
it work. Does anyone have any suggestions?


Thanks,
Hank
