helm() does not respect .tiltignore file

[digger18]

I have a helm chart which has subcharts in it (using requirements.yaml).
In my .tiltignore file I added *.tgz and placed it next to my Tiltfile.
After I do helm dep update in the helm chart directory (which fetches the subcharts as .tgz files to charts/ directory), Tilt enters a restart loop because it detects (and not ignoring) the newly modified/added .tgz charts.

thanks for the report! let me poke at this a bit and see if i can figure out what's happening

OK, I double-checked, and I think Tilt is working correctly here.

To make sure that charts don't trigger rebuilds, you need to add this to your .tiltignore

**/*.tgz
**/charts
**/tmpcharts

.tiltignore works like .dockerignore, and doesn't match subdirectories by default.

I'm going to

• add a note in the Helm documentation on this, since I expect other people will want to copy this stanza, and
• make sure we have a second bug about detecting infinte reload

added a note on this to the helm guide:
