<p>I was using the <code>helm upgrade -i xxx myfoo</code> to install/upgrade myfoo, </p>

<p>I follow all the standard doc, but this failure ALWAYS happend as soon as I upgrade at the 7th upgration!</p>

<p>When I began to upgrade at the 7th time, it told me below failure:</p>

<p><code>Error: UPGRADE FAILED: ConfigMap "myfoo.v7" is invalid: []: Too long: must have at most 1048576 characters</code></p>

<p>This is really frustrating! Why do this happen? </p>

<p>Thank you for your help, I now understand what's going on.</p>

<p>I added some bigger file in <code>chart/</code> dir, which cause the helm package size exceed 1M.</p>

<p>after remove these bigger files, it works back to normal. And I know why there is .helmignore file now, it is used to tell helm not include them in final helm package file(*.tgz)</p>
