reduce Alpine image size

[PhilipMay]

@ngosang sais:

it's possible to reduce Docker' images size to half. (if you do some changes in the Dockerfiles to avoid caching files and reduce the number of layers)

You can open another issue for that.

So - this is the issue - can yo provide some hints @ngosang ?

[ngosang]

Hint => https://github.com/matusnovak/prometheus-smartctl/pull/31/files

You can use this tool to inspect the layers => https://github.com/wagoodman/dive

[ngosang]

Image name: ghcr.io/philipmay/smart-prom-next:0.0.4rc1-alpine Total Image size: 71 MB Potential wasted space: 14 MB Image efficiency score: 89 %

Image name: matusnovak/prometheus-smartctl:v2.0.0 Total Image size: 52 MB Potential wasted space: 735 kB Image efficiency score: 99 %

done with Alpine - what else can be done with Alpine and / or Debian?

[ngosang]

Sorry, I don't have time to explain. You can reduce both Docker images even more as enhancement. You can close if you want.
