How to increment version inside a file?

Hi All,

I need to write a shell script which opens a file and increments the version(text) within the file every time the script runs. For example:

Code:
[user@server]$ cat docker_file.yml

version: '3.1'
services:
  ui:
    image: repo-srv.dev.io:5000/facebook/ui:0.0.2-QA1

[user@server]$


So, I would like to update version: 3.1 to version: 3.2 and ui:0.0.2-QA1 to ui:0.0.3-QA1 every time docker_file.yml is opened.

Thanks in advance!
