Helm diff always shows a diff in the caBundle

[lifelofranco]

I am currently using the AWS load balancer controller helm chart. Running diff always shows a revision in the caBundle.

I'm also having this issue, except with the letsencrypt chart, and the spec.acme.privateKeySecretRef.name value. Both strings are exactly the same, but show as a diffed line.

Note: I'm not a helm diff maintainer, this is a drive by comment because I was looking to debug something else. I probably won't be able to help much more.

Technically, there is a diff in the @lifelofranco's screenshot. It starts in the first line about 2-3 dozen characters in (SURQek vs SURREN).

Looking at the referenced helm chart, a new caBundle value is generated from random data each time you run helm (See offending line and genCa function). So diff is doing the right thing. The problem seems to be more with the chart.

For @katiekeel's screenshot, I'm stumped and I didn't find a letsencrypt chart in a quick search. Usually when I see something like that happen, it's either a trailing whitespace issue that's being preserved in one place and not the other, or one or more of the letters in one is a look-a-like unicode letter. Ie. visually the same, but byte-wise different. For this, I use either careful selection with the mouse to see if a hidden space is there, or pipe it to od -a to see what I get.

Note the 'sp' in the second one.

% echo foo | od -a
0000000    f   o   o  nl
0000004 
% echo foo\ | od -a
0000000    f   o   o  sp  nl
0000005
