Hi,
Just getting started with Ansible (1.9.2) and trying to get a playbook
configured to deploy the latest version of our developers code.
What I wanted to do was loop through the property files from the source,
and if there was a difference (by md5 comparison) prompt the user that they
should manually verify and confirm. The reason for this is that different
environments (lower test environments, production environments) may have
had optimizations that I don't want to overwrite blindly - or skip and miss
a change that should be deployed.
Even logging it at the end of the run would work from my perspective.
The following runs against a list of hosts (2 currently):
- hosts: webservice
vars:
local_path: /tmp/webservice-latest
tomcat_dest_path: /opt/tomcat/webapps
shared_classes_path: /opt/tomcat/shared/classes
webservice_files: [
{
sample_name: wrapper.properties.sample,
name: wrapper.properties,
src: "{{local_path}}/conf",
dest: "{{shared_classes_path}}"
}
]
tasks:
- name: Get local stat of all webapp files
become: no
local_action: stat path="{{item.src}}/{{item.sample_name}}"
with_items:
- "{{webservice_files}}"
register: local
- name: Get remote stat of all the webapp files
action: stat path="{{item.dest}}/{{item.name}}"
with_items:
- "{{webservice_files}}"
register: remote
- name: "Debug file stat for both local and remote - True"
debug: msg="Stat should be True
{{item.1.stat.path}}:{{item.1.stat.md5}}
{{item.2.stat.path}}:{{item.2.stat.md5}}"
when: '"{{item.2.stat.exists}}" == "True" and "{{item.1.stat.md5}}"
!= "{{item.2.stat.md5|default}}"'
with_together:
- "{{webservice_files}}"
- "{{local.results}}"
- "{{remote.results}}"
# if the property files do exist, then we need to tell the user
# and let them sort it out
- name: Compare md5 of webservice files that do exist, prompt if
different
pause: prompt="Files are different - manually review (enter to
continue)"
when: '"{{item.2.stat.exists}}" == "True" and "{{item.1.stat.md5}}"
!= "{{item.2.stat.md5|default}}"'
with_together:
- "{{webservice_files}}"
- "{{local.results}}"
- "{{remote.results}}"
Test Scenario:
For my test the remote file on server1 is different than the local file,
the remote file on server2 is identical.
Results:
I can see the debug line skipped for server2, and displayed for server1
which is correct.
The issue is that I only see the action skipped for server2, for server1 I
don't get a prompt or a notification that it was skipped. It just silently
skips it.
Any suggestions?
I am thinking that pause does not work when used within a loop (although
not documented here - http://docs.ansible.com/ansible/pause_module.html).
Even if I template the different environments property files, if someone
has made a change I would prefer to at least notify the person deploying
that there is an unexpected change in one of the files.
Cheers,
Craig
