Diff between Revisions

[sfrique]

Hello,

It would be great if it was possible to diff between already released versions.

Something like this, current release history:

$ helm history winsome-owl                                                                                                                                             [11:04:28]
REVISION        UPDATED                         STATUS          CHART           DESCRIPTION     
1               Wed Apr 12 18:23:28 2017        SUPERSEDED      api-0.1.0    Install complete
2               Wed Apr 12 18:25:55 2017        SUPERSEDED      api-0.1.0    Upgrade complete
3               Wed Apr 12 18:30:48 2017        SUPERSEDED      api-0.1.0    Upgrade complete
4               Wed Apr 12 18:32:39 2017        SUPERSEDED      api-0.1.0    Rollback to 2   
5               Thu Apr 13 00:08:00 2017        DEPLOYED        api-0.1.0    Upgrade complete

So to get a diff between revision 5 (current and 3)

$ helm diff winsome-owl 3

Or explicit get the diff between 4 and 1

$ helm diff winsome-owl 4-1

Thanks

Waiting for this feature..!!
Mean while, as a work around , we could use the helm get and sdiff/vimdiff to view the difference between two revisions side by side.

Using sdiff:

$ sdiff <(helm get $release --revision $revision_1 ) <(helm get $release --revision $revision_2)

To display only the changes use -s and -w flags

$ sdiff -s -w 80 <(helm get $release --revision $revision_1 ) <(helm get $release --revision $revision_2)

Using vimdiff:

$ vimdiff <(helm get $release --revision $revision_1 ) <(helm get $release --revision $revision_2)

Example:

$ sdiff <(helm get my_release --revision 4 ) <(helm get my_release --revision 5 )
REVISION: 4						      |	REVISION: 5

hi @sfrique,
I have implemented the above mentioned feature in this PR #21, have a look and let me know in case of corrections/bugs.

[sfrique]

@aananthraj Thanks a lot to take sometime to implement this!

Unfortunately I don't have the time to test it now =/
But when i get a change i will.

I am currently working on some charts, I may try to use this to see if it will help!

Thanks again for the effort!

[codenio]

@sfrique any updates..?
your inputs would be helpful for closing this issue.

[sfrique]

I will test it at beginning of April.
Sorry about the long delay.

[sfrique]

@aananthraj this PR says it's messed up.
What should i do?

[codenio]

@sfrique , can you be brief..?, couldn't understand.
Is PR #22 messed up...?

[sfrique]

@aananthraj i was checking PR #21
Sorry, will test once i have some time!

I believe this has been fixed by a536dfc and is shipped since version 2.9.0+1 of this plugin.
