MicroOS – The OS that does “just one job”

The openSUSE Summit 2020 kicked off yesterday. Like many others this summit was a virtual one too. It ran on a platform managed by openSUSE fan and user P. Fitzgerald.

I was busy with work stuff and couldn't watch the presentations live. I hopped on and off on the platform. I didn't want to miss Richard's presentation about MicroOS but yet I missed it. Luckily he was quick to record his session and upload it on YouTube. I got a chance to watch it afterwards. Surely, all other presentations will be available on openSUSE TV soon and I'll be able to catch-up.

If you didn't rush to watch Richard's presentation on YouTube right-away, here are a few hints that may encourage you to watch it.

openSUSE container registry

I'm not going to tell you what MicroOS is, you got to watch the video to learn about that, but did you know that the openSUSE project had a containers registry available publicly at https://registry.opensuse.org ? You can add it to the /etc/containers/registries.conf file and Podman can now search & pull containers from it.

Tiny openSUSE containers

When deploying your application in a container you always look for the fattest container, right? Of course, no!

openSUSE offers a small (Tumbleweed) busybox container that is just under 10 MB. Mini but mighty! 💪

How to keep a system patched & running?

If it's running you don't want to touch it, but, systems need security updates. Someone has to do the dirty-job. Who? Can a system update itself without breaking the applications that are running?

I had to screencap this :)

Health checks during boot-up

Have you ever had a system that fails to boot after an update? I had. MicroOS checks for errors during the boot phase and if a snapshot is faulty the system then boots up with the last known working snapshot. MicroOS does so without any manual intervention, so, automatic reboots are safe.  😀 🎉 🎊

Debugging your MicroOS container host

MicroOS is a lightweight system that doesn't come bundle with debugging tools (for obvious reasons). Once in a while though you need to troubleshoot things like network issues. There you go, you can spin a toolbox container and inspect the network interface on the host. 🛠️

I hope these are enough to convince you to watch the presentation and that openSUSE MicroOS becomes part of your servers infrastructure. 🐧

DevCon 2020 | Kubernetes – Introducing through openSUSE MicroOS & Kubic

Guest post by Chittesh Sham 😉

DevCon 2020 is just about three weeks away and the hype is real.

People know me as a friendly neighborhood SysAdmin and this year I am excited to announce that I will be co-hosting a presentation alongside Ish at the Developers Conference. It has been a long time coming, and as you might have noticed Ish has been building up to this one, starting with his Kubic Presentation at DevCon 2019 , openSUSE MicroOS in Production talk at openSUSE Conference 2019 and a workshop on Managing Pods & Containers at the openSUSE Asia Summit.

Half Left - Kubernetes Logo ; Half right MicroOS logo 😊

We have been experimenting with a bunch of tools such as Podman, Buildah, Skopeo and openSUSE Kubic for a while now and we would like to share our experience.

Our presentation is scheduled on Saturday 4 April 2020, 2:30pm - 3:15pm in the Kryptone room at the Caudan Arts Centre. We will also be around for all three days at the conference, so if you want to grab a coffee and geek out on openSUSE and Kubernetes, don't hesitate to hit us up!

I would like to give express my gratitude to the Linux Foundation and Cloud Native Computing Foundation (CNCF) for their support. I was impressed by Chris Aniszczyk, especially how quickly he reacted to show his support upon noticing our talk.

See you at DevCon Geeks! 🤓

DevCon is free to attend. How to register?

What is DevCon by the way?

First I need to tell you about the Mauritius Softwaree Craftsmanship Community (MSCC).

Some time around May or June 2013, Jochen Kirstätter (aka JoKi) started this trend called Code & Coffee, which was a weekly meetup on Wednesday mornings in a coffee shop to talk about programming or general tech stuff. He used to organize that under the umbrella of the Mauritius Software Craftsmanship Community, a user group which he started. Rumours circulate that JoKi sat all alone in a coffee shop for the first Code & Coffee meetup (TBC by Mary Jane, JoKi's wife).

I attended my first Code & Coffee meetup in June 2013 after learning about it from JoKi during a Linux meetup at L'Escalier organized by the Linux User Group of Mauritius. I don't recall having blogged about that first Code & Coffee meetup, but after the second one, yes I did blog about it.

MSCC meetup attendees grew over time and there were requests to also hold a Saturday monthly meetup. With a growing community we all became ambitious. Then in 2014 JoKi tossed the idea of having a "classic" conference which will be called the Developers Conference. After rigorous planning and support from both local and international sponsors, the first Developers Conference, dubbed as DevCon, happened on April 2015 at Voilà Hotel, Bagatelle.

DevCon attendance is a free of charge. It is an event full of business opportunities and professional networking. Attendees can learn about latest software development technologies, methodologies, as well as cloud features and infrastructure.

The aim of the conference is to provide local software developers a buffet of tools, practices and principles applicable to tackling current challenges in the Mauritian software development environment. From keeping up to date with the latest technologies and trends to tackling the challenges of working in large enterprise systems – it’s a buffet of experiences, ideas and pragmatic advice as well as an opportunity to connect with  peers across the industry.

Flashback: my blog post from DevCon 2015 Day 1

How to register?

Now that you know what DevCon is and how it started, let us talk about registration. MSCC events are published on meetup.com. That is where you would also register to attend DevCon.

Just head to the meetup page of MSCC, create an account and join the group.

Then, head to the DevCon event page and click on the attend button at the bottom of the page.

That's it, done. We'll see you at DevCon 2020. 😎

DevCon 2020 is just about a month away

The annual Developers Conference of Mauritius is happening on 2 - 4 April. That leaves us like about a month of final preparations.

A bunch of DevCon regulars met today during Code & Coffee at Mugg & Bean, Bagatelle, to attend to tasks related to the website, discuss about sponsorship, review talk proposals etc. Things are progressing and we are definitely looking forward to a great conference.

Two nights ago the conference website went live at conference.mscc.mu.

At the moment it's basically a conference announcement with registration pending to be opened and it contains a list of confirmed sponsors. Some of the sponsors are our regular supporters and we are thankful for their continued trust. As for the first timers we are just as eager to welcome them to this yearly awesomeness.

Once the registration opens, I'll blog more about the conference and provide details on what to expect this year. 😉

oSLO Conference 🐧

oSLO is short for openSUSE + LibreOffice.

The two projects are celebrating their 15ᵗʰ and 10ᵗʰ anniversary respectively in 2020. To mark the occasion, openSUSE and LibreOffice projects are organizing a joint conference from 13ᵗʰ to 16ᵗʰ October 2020 in Nuremberg, Germany. The conference will take place at Z-bau (Frankenstraße 200). It is the same location where last year's openSUSE Conference was held.

openSUSE and LibreOffice conferences are meant to bring like minded people together to discuss about topics relative to the projects. People can learn, teach and share their passion about the projects.

Last September, openSUSE announced a logo design competition for this co-conference with LibreOffice. Early this month the winner of the competition was announced. Kukuh Syafaat from Indonesia won the hearts of the co-conference organizing team.

The conference is free to attend. Mark you calendar & join the fun!

Call for Papers

The organizing team is currently accepting proposals for sessions. The deadline for submission is 21 July 2020.

Preps for the Developers Conference 2020…

Preparations for the Developers Conference 2020 have begun. The date, location and theme have been announced.

The next Developers Conference, simply dubbed DevCon 2020, will be held on 2 - 4 April at the Caudan Arts Centre in Port-Louis, Mauritius. This time the conference theme is Comics, which I am pretty sure requires no further explanation as to what to expect.

A few of our regular supporters have already joined as sponsors, while others have expressed their intention to back us financially in the coming days. The conference cannot happen without the help and support of the sponsors and the commitment to support the DevCon organizers every year is really appreciated. May the force be with you & your organizations prosper!

Developers Conference is an event by the community for the community. We should not forget this. Everyone's help is welcomed and appreciated. In fact, next year we're aiming big and the more backers we have the merrier!

If you believe there are organizations out there that can support us please share the conference brochure with them. The brochure explains about the conference, the different sponsorship tiers and ways in which an organization can help in making DevCon 2020 another great & awesome conference!

Meanwhile, you out there, if you've been to the Developers Conference before, then how about submitting a paper this time? Take the leap and do it!

Survey on the use of Linux in Mauritius

Who are we ?

The Linux User Group of Mauritius (LUGM) exists since November 2000 and our main roles are:

  • Advocate
  • Educate
  • Support
  • Socialise
  • Coordinate Linux and OSS activities in Mauritius

Web site and mailing list

  • http://www.lugm.org
  • http://www.lugm.org/mailing-list/

Scope of the survey

What we were looking for

  • Patterns of use of Linux and OSS in Mauritius
  • Meaning of Open Source
  • Knowledge of our existence

Methodology

  • Sample of 80-100 IT managers
  • Questionnaire based
  • Anonymous

The results: Heard about Linux ?

20030807-04-heard

A vast majority of IT managers has heard of Linux (92.5%)

The rest (7.5%) must be living on another planet 🙂

How did you discover it ?

20030807-05-how

Multiple answered we allowed.

We see the ever increasing role of the Internet as a means fo propagate knowledge.

Where do you use Linux ?

20030807-06-where

38% of the IT managers questioned do not use Linux, neither at work nor at home.

Of those 62% left, the majority use Linux only at work

This seems to indicate that Linux is being used as a server operating system.

Distribution used ?

20030807-07-distro

Pattern of use of distributions in Mauritius is exactly the same as worldwide.

Red Hat rules !

Applications used ?

20030807-08-what

Surprisingly, the type of application mostly used is Office applications (presumably Star Office and Open Office).

On the other hand, server applications (Mail, Web, Database and File Servers) amount to 55% which is coherent with the deduction made previously.

What about paid support ?

20030807-09-paid

A majority thinks that Linux support should not be commercial.

This is very surprising given that most of those questioned use Linux at work.

An interpretation is that they are satisfied with the level of support they get in forums and websites.

Deployment date ?

20030807-10-deploy

The majority of those questioned already have deployed Linux-based solutions at work. This is absolutely fantastic 🙂

Unfortunately, 35% do not know whether they’ll do it or not.

They are the ones we need to convince.

What is Open Source ?

20030807-11-whatis

One out of five IT managers does not know anything about Open Source…

Any Contribution ?

20030807-12-giveback

Frightening !

38% do not know how to help.

And about 20% do not want to help.

Linux and Open Source is all about give and take !!!

Heard about LUGM ?

20030807-13-knowlugm

55% of Mauritian IT managers know that LUGM exists.

Satisfied with LUGM ?

20030807-14-satisfied

About half of those who know LUGM are satisfied with it.

It is important that those who are unsatisfied with LUGM’s actions come forward and make proposals.

That’s the whole point of having a community…

Conclusions ?

A majority of Mauritian IT Managers

  • know Linux and Open Source software
  • have deployed Linux and OSS-based solutions
  • do not require commercial support
  • do not contribute to the OSS movement.

They could help

  • Technically <=> participate in OSS development
  • Financially <=> reward deserving developers & projects
  • Logistically <=> help in a LUG (for example LUGM :-))
