Yesterday, I was working on deploying features/PRs environments on the fly for a multi-tenancy Laravel app. To help me with this task where I had to jump between code, YAML files, and docker files, I used skaffold which is great to package all the standard steps "build, push, deploy" into one simple:
At one point I ran out of disk space so I decided to give a look at my docker images, to my dismay, I saw the php-fpm docker image was 3.67 GB big.
Let me introduce you to a beautiful tool called dive.
This tool lets you track layer by layer what is taking disk space in your docker image. It is so good, thanks to it I've found a residual 900 Mb Laradock folder imported twice in the docker image.
It makes it super easy to inspect what folders/files you could add to your
.dockerignore that you may have forgotten.
│ Image Details ├─────────────────────────────────── Image name: r******g/***fpm***:468xcbb5-dirty Total Image size: 614.04 MB Potential wasted space: 2.8 MB Image efficiency score: 99 %
They even have a CI option!
