What made your container fat?

Visualizing the size of Container Layers
D.containers
Dan Čermák
<p>Keeping the size of of your containers small is more important than ever, especially when distributing container images for others to build upon them. However, once multiple container layers get involved, even the data collection aspect becomes challenging and most existing tools do not primarily focus on visualization.</p> <p>We will present a simple tool that we created for this: it is a simple web app that produces sunburst graphs for each layer of a container image and can thereby aid you in finding out where the size bloat comes from. Go and grab it from https://github.com/dcermak/container-layer-sizes and give it a spin yourself!</p>

<p>Fed up with managing your host OS for your docker environment? Try booting your containers directly from a light-weight initramfs! Flash a USB pendrive with the kernel and initramfs, or netboot it locally or from the internet, configure it from the kernel command line. Bonus: It also supports syncing volumes with S3-compatible cloud storages, making provisioning and back-ups a breeze!</p>

<p>A user reports a bug. Its hardware/kernel/data specific. Is it fixed already? How do we get a debug container to the user to use and get meaningful results back?</p>

<p>Cloud brought many innovations - one of them is inexpensive, scalable and sometimes secure Distributed Storage options. In this presentation we will talk about distributed storage Options modern clouds offers ranging from elastic block devices and object storage to sophisticated transactional data stores. We will discuss the benefits and new architecture options such distibuted storage systems enable as well as the challenges pitfals you need to be aware about.</p>

<p>WebAssembly is a portable binary instruction format that was originally created with the browser as the main execution runtime. However, during the last years, WebAssembly is finding its way also outside of the browser because of the many benefits it provides like portability, security and flexibility. We think WebAssembly can be leveraged by Kubernetes in many ways. This short session will focus on how WebAssembly can be used to write Kubernetes admission policies. We will show an open ...
