Installing LimeSurvey with Docker on Ubuntu 16.04 with Nginx and Mariadb, Dave Lane, OERu Technology, Jun 20, 2018

I'll call this Downes's Simple Law: the more times a set of instructions says "simple" or "simply", the more difficult it will be to follow those instructions. Now because I'm pretty familiar with what the author is doing, for me it's not too diffiult to follow along (I just translate the Linux commands into Windows, for example). And I know to use NoteTab or Atom to create my text file. When I get to "install Nginx on your server" it gets a lot ... [Direct Link]

Hosting Futures, Jim Groom, bavatuesdays, May 25, 2018

I'm still in the mindset of "about what piloting a mashup of LAMP and Docker-container based hosting might look like." So I'm just as interested as Jim Groom in QUBES: “a community of math and biology educators who share resources and methods for preparing students to tackle real, complex, biological problems.” Groom adds that "QUBES is built on top of a project that came out of Purdue University called HUBzero, a service which provides focused ...

6 creative ways to solve problems with Linux containers and Docker, Sean Kane, O'Reilly, Mar 30, 2018

I've mentioned things like Docker and virtualization from time to time but haven't exactly addressed why these things would be interesting. This article helps fill that gap by offering six ways these solutions can solve problems such as read-only filesystems, solving operating system incompatibilities, or running specialized graphical applications.

Unblock Docker for Windows Firewall Issues with Host Volumes, Simon Williams,, Nov 26, 2017

We're not yet where stuff runs out of the box. This is a case in point. I spent all day on this issue, and it's basically Norton Firewall blocking access to shared volumes (ie., shared files) between my Windows system and a Docker container. I followed the instructions here (didn't need to execute the PowerShell command at the end) and now it seems to work, at lease with kitematics hello-world-ngnix. Source for this container isn't available, so I'm still trying to ... [Direct Link]

eLabFTW, Aug 15, 2017

This is really interesting. "With eLabFTW you get a secure, modern and compliant system to track your experiments efficiently but also manage your lab with a powerful and flexible database. If you do experimental research, then eLabFTW is for you. Whatever your field is. It is also well suited for teachers, or biotech companies." While it supports the idea of working openly, the implementation is also of interest. "eLabFTW is powered by PHP/MySQL in ... [Direct Link]

Why Skillshare runs on Kubernetes, Matias Forbord, Skillshare Writings, Jul 29, 2017

A few days ago I ran a post filled with tech jargon about something called Kubernetes. This is the antedote to that post, a down-to-earth practical example of how this technology is running applications in the learning technology space. The site in question is Skillshare, a subscription-based online curse library. The numers are impressive: 2 million students, 17000 classes, $5 million paid to teachers. Kubernetes manages cloud hosting for the site, managing a swarm of Docker containers, ... [Direct Link]

Docker Compose: A better way to deploy Rocketchat, Wekan, and MongoDB, Dave Lane, OERu Technology, May 30, 2017

I'm posting this mostly for my own future reference. It's basically a set of scripts that allow you to automate a cloud-based web application. is an open source messaging application similar to Slack. Mongo is a no-SQL database engine. And Wekan is a project management tool. Together they create a single working environment for a project team. Or a cool planning environment for your students. [Direct Link]

Open Distribution of Virtual Containers as a Key Framework for Open Educational Resources and STEAM Subjects, Alberto Corbi, Daniel Burgos, Electronic Journal of E-Learning, May 12, 2017

This paper (11 page PDF) covers an important topic and is one of the first detailed descriptions I've seen (not that others don't exist). The idea, in a nutshell, is that future OER distribution will be greatly enhanced by the use of virtualized containers. I've mentioned this a few times recently, referring to providers such as Vagrant or Docker. An example of this sort of thing in action is the Moodle in a box distributions that have been developed over the last five years. &... [Direct Link]

I So Want Try a Docker/Kitematic ContainerBook…, Tony Hirst, OUseful Info, May 12, 2017

We move one step closer to personal cloud-based environments. Here's Tony Hirst: "it seems as if VMWare’s Workspace ONE product, which is at the heart of the announcement, provides a secure online environment for launching managed, personally contextualised, virtualised services." But Hirst wants more. "What I keep thinking I’d like to have is a containerbook, rather than netbook. Think: Docker + Kitematic + Docker Compose + a browser." [Direct Link]

Installing Mautic with PHP7-FPM on Docker, Nginx, and MariaDB on Ubuntu 16.04, Dave Lane, OERu Tech, Mar 29, 2017

This is pretty interesting. Ignore the tech, unless you enjoy that, and focus on what it does. "Mautic is an open source marketing automation web application. Here at the OER Foundation, we use it to manage enquiries from prospective learners and partner institutions, to deliver timely emails to cohorts of learners undertaking our partner's online courses, and to measure our effectiveness in achieving our goals and mission: to makes higher education accessible to everyone." I should get ... [Direct Link]

Struggling = Learning, Karl Kapp, Kapp Notes, Jan 24, 2017

Papert called it "hard fun". We;ll, it has been fun but I've been swearing a lot recently. Getting to understand technologies like Docker and Vagrant - and all the associated middleware and protocols and conventions - has been a lot to undertake. I have a simple objective to start - create an image of gRSShopper and serve it from AWS. Why do it it this way? Why not just study what I need? Because if I want to truly understand it I have to build it. That's the point of Karl Kapp's ... [Direct Link]

Containers: Are they worth the hype?, IDG Connect, Dec 01, 2016

Not a deep article, but it will give you the basic idea of container tools such as Kubernetes from Google, Swarm from Docker, and CoreOS. Containers are a tye of virtualization, but they "don’t need to make a virtual copy of the host server’s hardware features, and they also don’t need a full copy of the host operating system to be installed within the container. This enables containers to be orders of magnitude more lightweight and flexible." [Direct Link]

A tour of Docker's components: Machine, swarm, compose, and more, Rick Fast', O'Reilly, Jun 01, 2016

More on Docker. "Docker has grown from a convenience wrapper to encompass an entire architecture. Learn how Docker's major components are related to each other." This is a short video highlighting the major elements of the Docker architecture. Really just a set of slides with an audio track. [Direct Link]

Docker as a Personal Application Runner, Tony Hirst, OUseful Info, May 09, 2016

Now that I have a lot more free time (during which I will not be writing program reports) I will have time to investigate what can be usefully done with technology like Docker. There's a lot here that accords with my own thinking about educational applications. Anyhow, this is a good post looking at Docker not as a virtual machine but rather one which "views containers from a single user, desktop perspective, seeing Docker and its ilk as providing an environment that can support off-...

How to Run A Shiny App in the Cloud Using Tutum, Digital Ocean and Docker Containers, Tony Hirst, OUseful Info, Dec 26, 2015

A few weeks ago I ran a link about running an application in a container in the cloud. The idea of this is that you create a complete operating system and server in a single package and run it on a cloud-based service. After I ran the post about the server ruunning Bluemix, Docker, and Watson, Tony Hirst published instructions describing how to run a Shiny app in the Cloud Using Tutum, Digital Ocean and Docker Containers. What's neat is that he stores the code in GitHub and sets ... [Direct Link]

Create cognitive plugins for Minecraft with Bluemix, Docker, and Watson, Kyle Brown, IBM Developer Works, Dec 10, 2015

OK, this is really really brilliant, but it will take a lot of brainpower to comprehend and even more to follow the instructions and make the whole thing work. But the concept behind what's happening here must not be passed by, and knowledge of some of the mechanics is essential to understanding the new world of applications programming. So here's the concept: you can put the intelligence of a large artificial intelligence like IBM's Watson into characters or objects that ... [Direct Link]

The Coming, Jim Groom, bavatuesdays, Jan 20, 2015

This is a very interesting project. As Jim Groom describes it, "Sandstorm is an open source platform that enables you to host open source applications that aren’t predetermined by more mainstream, highly controlled hosting software like CPanel... So, with Sandstorm you can basically provide an indie web distribution hub, kinda like the Merge or Dischord Records model for distributing alternative music."  Related: Docker. "Docker is an open platform for developers and ... [Direct Link]

Beginning to process the LA Reclaim Your Domain Hackathon, Brian Lamb, Edge, Aug 07, 2014

This is good stuff. "I’ve been intrigued by discussions concerning how things like AWS, Docker, OpenShift are shifting the software landscape, and wondering how something like UBC’s EduCloud might allow us to do some of these things while remaining compliant with our province’s FIPPA privacy legislation." And much much more. [Direct Link]
