Action's cache dirs are stored in working directory

[BjoernPetersen]

When using the v3 version of this action, I ran into an issue because the action stores its cache dirs docker-kube-config-[...] and helm-cache-[...] in the working directory. That will lead to an error 413 (Request Entity Too Large) when trying to install the chart in the working directory.

Anyone else affected reading this: add these lines to your .helmignore (create one if it doesn't exist) to work around this issue:

helm-cache-*/
docker-kube-config-*/

Oof good point, I'll update

github-action-helm3/main.js

Lines 18 to 23 in 45bd873

	const dockerKubeConfigDir = process.cwd() + '/docker-kube-config-' + Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, 13);
	fs.mkdirSync(dockerKubeConfigDir, {
	mode: 0o777,
	});
	const dockerKubeConfig = dockerKubeConfigDir + '/config';
	const helmCacheDir = process.cwd() + '/helm-cache-' + Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, 13);

to use the system tmp location.

v3.0.1 is out to fix this. Also found some other minor things to improve, but this one was causing issues, thank you for reporting 👍
