Takes snapshots of before and after clipboard changes and diffs them to show config changes
|
|
|
|
Takes an initial snapshot to /tmp
|
|
|
|
Then prompts for you to copy changes to the clipboard (eg. via UI changes and Configuration-as-Code copy)
|
|
|
|
Then takes another snapshot and diffs the two
|
|
|
|
Example Use Case:
|
|
|
|
Jenkins to backport settings to JCasC
|
|
|
|
1. copy the existing JCasC config from here to clipboard:
|
|
|
|
\$JENKINS_URL/manage/configuration-as-code/viewExport
|
|
|
|
2. run this script to save that clipboard to a file
|
|
|
|
3. then when prompted, reconfigure Jenkins in the UI
|
|
|
|
4. copy the new JCasC config from the page above to the clipboard
|
|
|
|
5. press enter to tell this script to continue to past the new clipboard to another file and diff for you
