app VS Lean and Mean Docker containers

For the CLI tool itself, you'd be looking at: https://github.com/apexpl/app/

You're right, in the "develop Your First Package" guide I use the get method, which is only available via Guzzle and it's not PSR-18 compliant. I did that for the sake of brevity, because I figured anyone viewing that guide will be using the default install which comes with Guzzle. If you look through the App package though (https://github.com/apexpl/app/) you'll see it only ever uses the PSr-18 compliant sendRequest method. Although Apex does come with Guzzle by default, developers are more than welcome to modify the ~/boot/container.php file and change that one entry out to any PSR-18 compliant implementation they would like such as Httpful or whatever, and I promise Apex will continue humming along just fine.

Please note, I didn't just pull SVN out of my ass, and a whole lot of planning and research went into this. Take a look at the code at https://github.com/apexpl/app/ and you'll see for yourself this is solid code. Are you by chance a PHP developer? If so, feel free to give this a test spin via Docker. The design is horrendous at the moment, but the network is online and solid -- https://apexpl.io/guides/develop_your_first_package

SlimToolkit empowers developers to create better, smaller, and more secure containers without sacrificing their existing workflows. Explore the project on GitHub or visit the official website to learn more.

And if you want to make the container quickly secure without bloats, maybe give this a try https://github.com/slimtoolkit/slim

Slim.ai presents the data in a more user friendly way than many of the other tools in this post. On top of its open source SlimToolkit for identifying the contents of an image, Slim.ai uses Trivy for vulnerability scanning.

What about https://github.com/slimtoolkit/slim?

A last practice that I do not use at all and which may interest you is to use slim toolkit to keep only the useful elements in your final image.

Anyone tried using https://github.com/docker-slim/docker-slim To minify an image?..

Distroless images are better left for people with serious need for lightweight images and good Linux knowledge because they require lot of planning with the build so that they stay light and work. If you need lighter images but docker isn't your main tool and you can't afford to take hours and hours of practicing different build strategies you can check docker-slim (https://dockersl.im/). With this tool you can easily size down the images.
