  • Docker spouts cash, sucks up Tutum

    Docker has hoovered up container hosting outfit Tutum, creating what the cash-packed buyer claims will be a complete platform to build, ship and run distributed applications.

    Both companies are privately held, and financial terms were not disclosed. It seems safe to assume the deal will add nothing to Docker’s bottom line or indeed its top line, for now.

    Tutum’s pricing page claims the service is “limitless” and free while it is still in beta, with a professional service promised sometime in the future.

  • Tutum Buyout Gives Docker Inc. Container Deployment Prowess

    Docker Inc. continues to extend its reach. Tutum's technology enables the deployment of Docker containers to the cloud and even developer laptops.
    Docker Inc. has a full portfolio of products and service for organizations building and managing containers, but how do your users actually deploy containers? That's a question that Docker Inc., the lead commercial sponsor behind the open-source Docker container effort, is now answering with the acquisition of privately held Tutum.

  • DevOps case study: Rabobank cuts deployment by 60 percent

    A company’s capacity to keep customers happy, capture new markets or engage business in new ways is often dependent on its IT department’s ability to create and release software. Yet the pace of releasing this software is no longer an annual or semi-annual event, but rather a continuous flow of new iterations and adjustments to meet market needs as they evolve and change. DevOps is breaking down the barriers between departments. Continuous delivery is providing an end-to-end framework that can help IT teams deliver software in an automated fashion.

  • OpenStack Security Groups using OVN ACLs

    It’s worth looking at how this has been implemented with OVS in the past for OpenStack. OpenStack’s existing OVS integration (ML2+OVS) makes use of iptables to implement security groups. Unfortunately, to make that work, we have to connect the VM to a tap device, put that on a linux bridge, and then connect the linux bridge to the OVS bridge using a veth pair so that we have a place to implement the iptables rules. It’s great that this works, but the extra layers are not ideal.

  • Oracle Puts OpenStack into Docker Containers

    There is a misconception among some people that Docker containers and OpenStack are competitive technologies. The truth is the exact opposite, and in fact, Oracle is now providing the best proof yet by using Docker images as a mechanism to actually install an OpenStack cloud.

  • OpenStack Addresses Network Orchestration Layer

    While the OpenStack community likes to present a unified front to the outside world, inside the various projects that make up the OpenStack framework, there is a lot of frustration with the Neutron networking component of OpenStack. Much of that frustration stems from the fact that after five years of effort Neutron still doesn't scale particularly well. As such, many of the organizations that have embraced OpenStack wind up swapping in a commercial network layer of software to replace Neutron.

  • Exposing the Truth About OpenStack Cloud Deployments

    Lured by the siren song of better business agility and accelerated innovation, an increasing number of companies are considering or have already deployed private clouds as part of their IT strategy. Since emerging in 2010 as an open-source initiative to help organizations build cloud services on industry-standard hardware, OpenStack has garnered much attention, but its adoption in production environments has been tempered by an assortment of perceived limitations, both real and imagined.

It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
