K3s is an official Cloud Native Computing Foundation sandbox project that brings a lightweight, fully compliant Kubernetes distribution designed for lower resource production models like remote locations or on an IoT device. When used in conjunction with Rancher, K3s can easily be managed from within the Rancher orchestration platform.
Rancher is a complete software stack used to deploy containers. It addresses the operational and security hurdles of operating multiple Kubernetes clusters across an infrastructure. Rancher provides DevOps teams with multiple integrated tools for running containerized workloads.
High-Availability K3s Server with an External DB Single server clusters can meet various use cases. Still, for environments where the Kubernetes control plane uptime is critical, you can run K3s in an HA configuration. An HA K3s cluster consists of two or more server nodes that will serve the Kubernetes API and run other control plane services An external datastore (as opposed to the embedded SQLite datastore used in single-server setups)
K3s can be configured in multiple ways. It can be used as a single server setup using an embedded database such as SQLite or a high availability K3s server cluster using an external database. In the image shown below, the framework is demonstrated in a high availability setup.
Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
Welcome to this on Docker Tutorial for Beginners. In this video provides an Introduction on C++ development with Docker containers. So we will see How to ship C++ Programs in Docker.
“Docker: Understanding Docker Architecture and Components”, The First thing we are going to do is to run the “docker run hello-world” command. This command tries to find the “hello-world” image locally and if not found, it then downloads an image from the docker hub and runs the container out of this image.
This entry-level guide will tell you why and how to Dockerize your WordPress projects.
Manage Data in Docker -Understanding “Docker Volumes” and “Bind Mounts”. Volumes are stored in a part of the host filesystem which is managed by Docker (/var/lib/docker/volumes/ on Linux). Non-Docker processes should not modify this part of the filesystem. Volumes are the best way to persist data in Docker.
