An Ansible AWX operator for Kubernetes built with Operator SDK and Ansible.

This Ansible playbook is meant to help you run your own Matrix homeserver, along with the various services related to that.

That is, it lets you join the Matrix network using your own @<username>:<your-domain> identifier, all hosted on your own server (see prerequisites).

We run all services in Docker containers (see the container images we use), which lets us have a predictable and up-to-date setup, across multiple supported distros (see prerequisites) and architectures (x86/amd64 being recommended).

Installation (upgrades) and some maintenance tasks are automated using Ansible (see our Ansible guide).

Heute läuft der Server mit Ubuntu 20.04. Darauf laufen keine LXC/LXD Container mehr. Stattdessen läuft jetzt Kubernetes darauf. Zu Beginn nutzte ich für die Installation von Kubernetes Kubespray ein, das Standard-Kubernetes war allerdings deutlich zu fett. Größtes Manko war, dass das etcd verdammt viel auf die SSD geschrieben hat und ich regelmäßig bei jedem Upgrade das Setup kaputt gespielt habe. Für den Privatgebrauch ergab das so daher keinen Sinn.

Mittlerweile setze ich auf das vergleichsweise schlanke k3s.io. Das braucht im Heimbetrieb deutlich weniger Leistung und erledigt trotzdem das, was ich brauche. Statt etcd setzt es auf sqlite und statt Docker auf containerd.

This guide shows how to provision and manage remote Docker Hosts with Docker Machine on your OpenNebula cloud.

Algo VPN is a set of Ansible scripts that simplify the setup of a personal IPSEC and Wireguard VPN. It uses the most secure defaults available, works with common cloud providers, and does not require client software on most devices. See our release announcement for more information.

DBdeployer is a tool that deploys MySQL database servers easily. This is a port of MySQL-Sandbox, originally written in Perl, and re-designed from the ground up in Go. See the features comparison for more detail.

• Can be deployed on AWS, GCE, Azure, OpenStack, vSphere, Oracle Cloud Infrastructure (Experimental), or Baremetal
• Highly available cluster
• Composable (Choice of the network plugin for instance)
• Supports most popular Linux distributions
• Continuous integration tests

kubeadm helps you bootstrap a minimum viable Kubernetes cluster that conforms to best practices. With kubeadm, your cluster should pass Kubernetes Conformance tests. Kubeadm also supports other cluster lifecycle functions, such as upgrades, downgrade, and managing bootstrap tokens.

Because you can install kubeadm on various types of machine (e.g. laptop, server, Raspberry Pi, etc.), it’s well suited for integration with provisioning systems such as Terraform or Ansible.

kubeadm’s simplicity means it can serve a wide range of use cases:

New users can start with kubeadm to try Kubernetes out for the first time.
Users familiar with Kubernetes can spin up clusters with kubeadm and test their applications.
Larger projects can include kubeadm as a building block in a more complex system that can also include other installer tools.

kubeadm is designed to be a simple way for new users to start trying Kubernetes out, possibly for the first time, a way for existing users to test their application on and stitch together a cluster easily, and also to be a building block in other ecosystem and/or installer tool with a larger scope.

You can install kubeadm very easily on operating systems that support installing deb or rpm packages. The responsible SIG for kubeadm, SIG Cluster Lifecycle, provides these packages pre-built for you, but you may also on other OSes.

There are multiple ways to run a Kubernetes cluster with Ubuntu. These pages explain how to deploy Kubernetes on Ubuntu on multiple public and private clouds, as well as bare metal.

Elixir ❤️ Embedded

Nerves is an open-source platform that combines the rock-solid BEAM virtual machine and Elixir ecosystem to easily build and deploy production embedded systems.

Foreman is a complete lifecycle management tool for physical and virtual servers. We give system administrators the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage servers, on-premise or in the cloud.

Provision from anywhere

Bare metal, Amazon EC2, Google Compute Engine, OpenStack, Libvirt, oVirt, VMware, and many other providers allow you to manage a hybrid cloud through Foreman

Configuration

An external node classifier, hiera-like parameters, and reports monitoring for Puppet, Salt and Chef are included. Completely ready to tweak host groups in your data center.

Nachdem die hybride Cloud aus Windows- und Linux-Systemen dank Packer und Vagrant zur Verfügung steht, soll Ansible jetzt einen Docker Swarm automatisiert initialisieren und das Deployment vorbereiten.

Eine hybride Cloud aus Windows- und Linux-Systemen kann kompliziert sein: Docker Swarm und Ansible sind jedoch zwei Tools die dabei helfen können, die Container auch über System- und Servergrenzen hinweg kontrollieren zu können.

Containers are a great solution for consistent software deployments. When you start using containers in your environment, you and your team will quickly realise that you need a system which allows you to automate container operations. You need a system to keep your containers running when stuff breaks (which always happens, expect failure!), be able to scale up and down, and which is also extensible, so you can interact with it or built upon it to get the functionality you need. The most popular system for deploying, scaling and managing containerized applications is Kubernetes.

GitLab has integrated CI/CD pipelines to build, test, deploy, and monitor your code.

The benefits of Continuous Integration are huge when automation plays an integral part of your workflow. GitLab comes with built-in Continuous Integration, Continuous Deployment, and Continuous Delivery support to build, test, and deploy your application.

Ignition is a new provisioning utility designed specifically for CoreOS Container Linux. At the the most basic level, it is a tool for manipulating disks during early boot. This includes partitioning disks, formatting partitions, writing files (regular files, systemd units, networkd units, etc.), and configuring users. On first boot, Ignition reads its configuration from a source-of-truth (remote URL, network metadata service, hypervisor bridge, etc.) and applies the configuration.

Even though Ignition only runs once, it packs a powerful punch. Because Ignition runs so early in the boot process (in the initramfs, to be exact), it is able to accomplish configuration all before the userspace has begun booting, which enables advanced features that Container Linux admins require.

Kolla’s mission is to provide production-ready containers and deployment tools for operating OpenStack clouds.

This documentation is for the Kolla container images. The following subprojects are available to help deploy Kolla:

• kolla-ansible
• kolla-kubernetes

General support for:

• Monitors
• OSDs
• MDSs
• RGW

More details:

• Authentication (cephx), this can be disabled.
• Supports cluster public and private network.
• Monitors deployment. You can easily start with one monitor and then progressively add new nodes.
  So can deploy one monitor for testing purpose. For production, I recommend to always use an odd
  number of monitors, 3 tends to be the standard.
• Object Storage Daemons. Like the monitors you can start with a certain amount of nodes and then
  grow this number. The playbook either supports a dedicated device for storing the journal or both
  journal and OSD data on the same device (using a tiny partition at the beginning of the device).
• Metadata daemons.
• Collocation. The playbook supports collocating Monitors, OSDs and MDSs on the same machine.
• The playbook was validated on Debian Wheezy, Ubuntu 12.04 LTS and CentOS 6.4.
• Tested on Ceph Dumpling and Emperor.
• A rolling upgrade playbook was written, an upgrade from Dumpling to Emperor was performed and worked.
