Find/list files with specific extension and rename them dynamically using ansible playbook - ansible

Question

I'm trying to rename a jar file in a path for deployment using ansible and it is successful. I have tried multiple ways but still, it's failing,
For example, there are multiple Jar files in the path /appdata/tomcat/lib/jars/
we havemultiple jar files with version numbers like below
app_deploy-1.1.1.jar
app_deploy-1.1.2_old_1.jar
app_deploy-1.1.2.jar_before
app_deploy-1.1.2_old_2022.jar
app_deploy-1.1.2_before.jar
I have move all files with .jar extension with date using custom date variable {deploy_date} like this app_deploy-1.1.2_before.jar_{deploy_date}
I have method 1 as below :
- name: Get the name of the current jar files
shell: ls -l /appdata/tomcat/lib/jars/ | grep .*.jar
register: jar_files_list
- debug:
msg: "{{ jar_files_list }}"
- name: Get the date
shell: date +%Y%m%d%H%M%S
register: timestamp
when: jar_files_list.stdout != ''
- name: Rename the current jar file
file:
src: /appdata/tomcat/lib/jars/{{ jar_files_list }}
dest: /appdata/tomcat/lib/jars/{{ jar_files_list }}_{{ ansible_date_time.date }}_backup
when: jar_files_list.stdout != ''
I have method 2 as below :
- name: Rename the current jar files
shell: mv /appdata/tomcat/lib/jars/*.jar {{ repo_name }}-*.jar_backup_{{ ansible_date_time.date }}
- name: Move current filesto backup directory
shell: mv /appdata/tomcat/lib/jars/{{ repo_name }}-.*.jar /appdata/tomcat/lib/jars//backup_jars/`
Both of the solutions doest work, can someone help me with some solutions

Answer 1

The find module can be used to find and generate a list of files located on a remote host based on a pattern:
- name: Get jars in {{ jars_path }}
find:
paths: "{{ jars_path }}"
file_type: file
patterns: '*.jar'
register: jars_list
The output will be a dictionary of only the *.jar files in the specified path:

"{{ jars_list.files }}" will list the files and .path will provide the full path of the file.
Now the copy module with the option remote_src: yes can be used to rename the files:
- name: Rename jars
copy:
src: "{{ item.path }}"
dest: "{{ item.path }}_{{ deploy_date }}"
remote_src: yes
loop: "{{ jars_list.files }}"
Delete the old files:
- name: Remove old jars
file:
path: "{{ item.path }}"
state: absent
loop: "{{ jars_list.files }}"
The complete playbook
- hosts: all
vars:
deploy_date: "{{ ansible_date_time.date }}"
jars_path: /appdata/tomcat/lib/jars
tasks:
- name: Get jars in {{ jars_path }}
find:
paths: "{{ jars_path }}"
file_type: file
patterns: '*.jar'
register: jars_list
- name: Rename jars
copy:
src: "{{ item.path }}"
dest: "{{ item.path }}_{{ deploy_date }}"
remote_src: yes
loop: "{{ jars_list.files }}"
- name: Remove old jars
file:
path: "{{ item.path }}"
state: absent
loop: "{{ jars_list.files }}"
