Deploy a Kubernetes Cluster with Service Mesh on DigitalOcean Using K3s

Deploy a Kubernetes Cluster with Service Mesh on DigitalOcean Using K3s
This guide will help you set up a Kubernetes cluster, including a service mesh using k3s (at the time of writing at version 0.10.2) and Rio. We’ll deploy the cluster on DigitalOcean. Ubuntu 18.04 LTS will be the OS during this tutorial. If you sign up to DigitalOcean using this link, you’ll receive $50 to spend on their services over 30 days. If you wish to run your cluster on your own hardware, you could do so on Raspberry Pis (ARM64) or Intel NUCs (x86_64) for example.

Deploy Bitwarden on Docker Swarm

Deploy Bitwarden on Docker Swarm
In this tutorial, we’ll deploy Bitwarden on Docker Swarm. It’s based on an earlier tutorial on this site, where we deployed Docker Swarm on DigitalOcean. Bitwarden is a password manager with support for self-hosting. We’ll use bitwarden_rs, an unofficial Bitwarden API server implementation, as it’s a bit faster than the default implementation. Bitwarden_rs is written in Rust and is compatible with the official Bitwarden clients. Bitwarden has the following features, among others:

Deploy GitLab CE on Docker Swarm

Deploy GitLab CE on Docker Swarm
This short tutorial demonstrates how simple it is to deploy applications, in this case GitLab CE, with a Docker Swarm cluster. It builds on the last one, which deployed a Docker Swarm cluster on DigitalOcean. GitLab CE can also be installed and run on a bare-metal server as well. It assumes you have a Docker Swarm cluster running and that you have root access to your nodes. Prepare Manager Node First, GitLab CE requires a decent amount of resources.

Create a Docker Swarm Cluster on DigitalOcean

Create a Docker Swarm Cluster on DigitalOcean
This tutorial will guide you through the process of setting up a Docker Swarm cluster on DigitalOcean. It’ll also show you how to deploy Traefik as a reverse proxy for your services and Swarmpit as a web interface for your cluster. We’ll use Fedora 30 as the OS for this tutorial. If you sign up to DigitalOcean using this link, you’ll receive $50 to spend on their services over 30 days.

Deploy a Three-Node Kubernetes Cluster on Fedora 30 on DigitalOcean

Deploy a Three-Node Kubernetes Cluster on Fedora 30 on DigitalOcean
Today, we’ll deploy a three-node Kubernetes cluster on top of Fedora 30. We’ll run the nodes on VMs in DigitalOcean’s data centers. DigitalOcean also offers a managed Kubernetes deployment, but we’ll deploy it manually using kubeadm here. We will end up with a single control-plane cluster, i.e., lacking High Availability (HA) features. Using this link to DigitalOcean will grant you $50 to spend on DigitalOcean services over 30 days for free.

Install LXD on Alpine Linux

In this tutorial, we’ll install LXD, configure our system to run LXC containers, and initialize LXD on Alpine Linux. It should work on all platforms where LXD/LXC is supported (x86_64, ARM64, and more). Alpine Linux is “an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency.” It’s incredibly lightweight and useful for containers and virtual machines as both a host and a guest.
