Ansible file processing / blockinfile module in Windows
The Ansible blockinfile
module is not supported on Windows because it relies on the file manipulation capabilities provided by the target operating system. However, you can achieve similar functionality on Windows using alternative methods.
One approach is to use the win_lineinfile
module, which allows you to insert or update a line in a file on a Windows system. Here's an example playbook demonstrating how to use win_lineinfile
:
yaml- name: Insert block into a file on Windows
hosts: windows
tasks:
- name: Insert block into file
win_lineinfile:
path: C:\path\to\file.txt
insertafter: EOF
line: |
# Begin Block
This is the first line of the block.
This is the second line of the block.
This is the third line of the block.
# End Block
In the above example, the path
parameter specifies the path to the file where you want to insert the block. The insertafter
parameter defines the pattern or marker after which the block should be inserted. In this case, we are using EOF
to insert the block at the end of the file. Finally, the line
parameter is used to specify the contents of the block.
Alternatively, if you need to update an existing block in a file, you can combine the win_lineinfile
module with the block
module to search for the existing block and replace it with a new one. Here's an example:
yaml- name: Update block in a file on Windows
hosts: windows
tasks:
- name: Find and replace block in file
block:
- name: Read file contents
win_shell: Get-Content C:\path\to\file.txt -Raw
register: file_contents
- name: Update file contents
win_shell: |
$newContents = $file_contents.content -replace '(?s)# Begin Block.*?# End Block', '
# Begin Block
This is the new first line of the block.
This is the new second line of the block.
This is the new third line of the block.
# End Block'
$newContents | Set-Content C:\path\to\file.txt
In this example, we first read the contents of the file using win_shell
and store it in the file_contents
variable. Then, we use PowerShell to update the contents by replacing the existing block with a new one. Finally, the updated contents are written back to the file using Set-Content
.
Remember to adjust the paths and content according to your requirements and ensure that you have the necessary permissions to modify the specified file.
