我的 Ansible 服务器和远程计算机上有一个 Java 属性文件
服务器:/opt/deployment/application/build.properities
app=application
build=1.0.15
etc=etc
远程计算机上有相同的文件(如果已安装),其中可能包含较新或较旧的版本
远程:/opt/application/build.properities
app=application
build=1.0.13
config1=config
etc=etc
我可以使用 ansible.builtin.ini 将远程计算机上的内部版本号与服务器进行比较,并且:
if server > remote - do my upgrade block
if remote == "" (file does not exist) - do my install block
otherwise do nothing
我不清楚 ansible.builtin.ini 是针对本地服务器还是远程计算机(我可能错过了一些东西)。如果有区别的话,两台机器都是 Ubuntu Linux。

只是为了在我发表评论后提供大局。复制文件并通知处理程序(如果发生更改)。或者,您可以在任务上注册一个变量并进行检查,when : <registered_var>.changed
但通常首选处理程序。

我最终成功地完成了这个工作,并想分享我使用的代码......
- name: Check if App is installed
stat:
path: "{{ app_buildfile }}"
register: APPbuildfile
- name: Get Build Number
shell: grep build {{ APP_buildfile }} | awk -F'=' ' { print $2 } ' | tr -d ' '
when: APPbuildfile.stat.exists
register: APP_currentbuild
- debug:
msg: Current version {{ APP_currentbuild.stdout }}, Deployment Version {{ APP_deployment_version }}
