An Overview of Kubernetes Security Projects at KubeCon Europe 2023
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.

M1: Docker doesn't find shared x64 shared objects even though platform was specified
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.

I deleted 78% of my Redis container and it still works
Maybe this would help in that regard: https://github.com/docker-slim/docker-slim

Are there tools that tell you if you can optimize your dockerfiles?
I have heard of slim.ai, there core tool is open source https://github.com/docker-slim/docker-slim
- We're optimizing our Docker image and we're pretty happy with how it's going: 3.37GB > 1.13GB. Next stop, a single Docker image Budibase deployment 🚀

Down With the Sickness
In last weeks blog I talked about what my plan was for release 2.9. My main areas of concern was finishing the migration to make use of the images stored in our Docker registry. The other area I was planning on taking on was to slim down those images in the registry by using Docker-Slim.

The 2024 Web Hosting Report
To manage a VM, you can use something as simple as just manual actions over SSH, or can use tools like Ansible, Hashicorp's Packer and Terraform or other automations. For an app where there is minimal load and security/reliability concern, VMs are still a great option that provide a lot of value for the buck

DevOps Tooling Landscape
HashiCorp Packer is a tool for creating machine images for a variety of platforms, including AWS, Azure, and VMware. It allows you to define machine images as code and supports a wide range of configuration options.

auto-provisioning multiple raspberry pi's
Packer is a tool that can be used to build machine images. Basically, it takes a base image, runs a series of steps to provision that image, and then burns a new image. In my workplace we use it heavily to build AWS AMIs. But it has an ARM plugin that looks to be very very suitable for building customised Raspberry Pi images (my quick read of the doco there says it can go ahead and write the final image to an SD card for you too).

Virtualbox 7.0.4 kickstart issue
However, I was unable to build the boxes with packer for some reason. It turned out that this wasn't an easy to fix or obvious issue. In fact, I had to search quite hard to find an answer. I am pretty sure my friend Tim Hall (oracle-base) ran into this issue too. Finally, I found a description of the issue on packer GitHub: Packer 1.8.4 not working with Virtualbox 7.0.4+ #12118.
I was building a new version of YugabyteDB vagrant box with packer and virtual box. Because we (Yugabyte) have a new preview release out.
