With ansible-builder you can configure and build portable, consistent, customized Ansible control nodes that are packaged as containers by Podman or Docker. These containers are known as execution environments. You can use them on AWX or Ansible Controller, with Ansible Navigator, for local playbook development and testing, in your CI pipelines, and anywhere else you run automation.
You can design and distribute specialized execution environments for your Ansible content, choosing the versions of Python and ansible-core you want, and installing only the Python packages, system packages, and Ansible collections you need for your tasks.
kaniko is a tool to build container images from a Dockerfile, inside a container or Kubernetes cluster.
Important
This is a supported replacement of the original GoogleContainerTools/kaniko repository, which was archived in June of 2025. Further details in History and Status.
kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster.
kaniko is meant to be run as an image. We do not recommend running the kaniko executor binary in another image, as it might not work as you expect - see Known Issues.
uCore is an OCI image of Fedora CoreOS with "batteries included". More specifically, it's an opinionated, custom CoreOS image, built daily with some common tools added in. The idea is to make a lightweight server image including commonly used services or the building blocks to host them.
Please take a look at the included modifications, and help us improve uCore if the project interests you.
Let’s talk about Docker and Nix today. Before explaining what Nix is, if you don’t know yet, and before going into the details, I will show you a snippet similar to a Dockerfile for creating a Redis image equivalent to the one in docker hub.
The final image will be around 42mb (or 25mb) in size, compared to 177mb.
EDIT: as mentioned on HN, alpine-based images can even go around 15mb in size.
If you want to try this, the first step is to install Nix.
Dieser Artikel gibt meine Motivation für den Bau von Container-Images und die Vorgehensweise wieder und zeigt, wie ich mit Buildah meine OCI-kompatiblen Container-Images erstelle.
Es handelt sich dabei mehr um einen Erfahrungsbericht als ein Tutorial und ich erhebe keinen Anspruch auf Vollständigkeit. Das behandelte Beispiel ist jedoch zum Einstieg und zur Nachahmung für all jene geeignet, die Container ausführen können und diese gerne ohne Verwendung von Containerfiles bauen möchten.

This image uses Alpine Linux 3.20.1 as base image.
ubi8-asciidoctor
A utility image for the UBI8 image + asciidoctor.
Contains the primary used asciidoctor-pdf for generating reports.
It's base is from https://github.com/asciidoctor/docker-asciidoctor but now ubi based.
Purpose
Useful for environments where these libraries/tools are needed such as:
- local development
- CI tools that do not require specific CI tooling configuration, such as GiLab Jobs.
Published

Die Image WB in FreeCAD dient dazu, Grafiken (Bilder, Fotos, techn. Zeichnungen) als Referenzen in FreeCAD einzuladen. Auf deren Basis kann man anschließend 3D-Modelle erzeugen.
In diesem Video wird der FreeCAD 0.19 Image Arbeitsbereich im Detail vorgestellt - alle Befehle der WB werden ausprobiert und es gibt noch ein paar Hinweise zum Workflow.
Docker can build images automatically by reading the instructions from a Dockerfile. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. Using docker build users can create an automated build that executes several command-line instructions in succession.
This page describes the commands you can use in a Dockerfile. When you are done reading this page, refer to the Dockerfile Best Practices for a tip-oriented guide.
live-wrapper is a tool initially produced by the Debian Live Team that can be used to create Debian-based live images for use with CDs, DVDs or USB sticks.
Welcome to the site for Buildah. This site features announcements and news around Buildah, and occasionally other container tooling news.
Buildah - a tool that facilitates building Open Container Initiative (OCI) container images - github
The Buildah package provides a command line tool that can be used to
- create a working container, either from scratch or using an image as a starting point
- create an image, either from a working container or via the instructions in a Dockerfile
- images can be built in either the OCI image format or the traditional upstream docker image format
- mount a working container's root filesystem for manipulation
- unmount a working container's root filesystem
- use the updated contents of a container's root filesystem as a filesystem layer to create a new image
- delete a working container or an image
- rename a local container
