I'm installing a local Helm chart; however, I keep getting an error Error: UPGRADE FAILED: create: failed to create: Request entity too large: limit is 3145728. From searching other SO/Stack Exchange questions, this is typically caused by unnecessary files mistakenly included in the chart. The way to resolve this, is to add those entries to a .helmignore file.

My chart has a .helmignore file, which should be excluding all unnecessary artifacts within my chart, but I'm still getting the error. So my thought is that my .helmignore entries aren't quite targeting the files that they should be.

I've tried running them with the --debug flag (didn't show anything more interesting):

upgrade.go:139: [debug] preparing upgrade for chartname
upgrade.go:520: [debug] copying values from chartname (v11) to new release.
upgrade.go:147: [debug] performing update for chartname

I also tried it with the --dry-run flag and the chart succeeded. So at this point I'm not sure how to find what's bloating my chart.

How can I tell which files are actually getting ignored (or which are included) when I run a helm install or helm upgrade?

Figured out a way, but it might not be the most elegant.

First, we render the chart locally and then use tree to print out the subdirectories with their sizes in a human-readable format.

helm template . --output-dir=file-size-test
tree --du -h file-size-test

This produces an output similar to:

[340M]  testing123
└── [340M]  chart_name
    ├── [ 91K]  charts
    │   ├── [ 58K]  sub-chart
    │   │   └── [ 58K]  templates
    │   │       ├── [1.3K]  deployment.yaml
    │   │       ├── [ 411]  config.yaml
    │   │       ├── [ 579]  service.yaml
    │   │       └── [ 359]  serviceaccount.yaml
<truncated>
    └── [340M]  templates
        ├── [ 68M]  deployment.yaml
        ├── [136M]  config1.yaml
        ├── [136M]  config2.yaml
        └── [1.3K]  ingress.yaml

So now I've found that the issue seems to be the massive config1.yaml and config2.yaml files.

While this doesn't exactly answer the question of how to find which have been ignored, it at least points to which might not have been ignored.
