Monthly Snap June

June kept everyone busy with and excited about the Open Source Data Conference in Berlin. Eleven days before OSDC Keya started the „OSDC 2018 Countdown“. Second week of June the NETWAYS headquarter in Nuremberg was quite quiet. Everyone flew off to Berlin. Everyone? Well, not entirely… One small group of NETWAY-ers kept the NETWAYS flag flying in Nuremberg. Thankfully they had sent a great conference reporter out: Every evening Dirk summed up what had happened in „The Future of Open Source Data Center Solutions – OSDC 2018 – Day 1“ and „… 2“. He also wrote about the „Open Source Camp Issue #1“ . OSCamp will give Open Source projects a platform to present themselves to the Community. This year it started with Foreman and Graylog.

Berlin Events are over for this year, but other great events cast their shadows ahead: „Now is the time to register“ for the upcoming Open Source Monitoring Conference. OSMC takes place in Nuremberg, November 5 to 8.

There is this German saying: „Alles neu macht der Mai“ – for NETWAYS it was June: For OSMC we have created new presentations formats, learn more in „OSMC 2018: Choose what suits you!” And: Julia is new. She just started this month as Marketing Manager and introduced herself in our blogseries „NETWAYS stellt sich vor“. Also new: We have published a „Ceph Training “, as Tim is happy to announce.

At times of DSVGO for Christoph it’s time to reconsider data protection of monitoring servers. In „Einfaches verschlüsseltes Backup“ he explains how one can use GPG to encrypt an icinga2 backup. Nicole shared her thoughts on the „Microsoft and GitHub – merge conflict?“ and recommends to get your own GitLab instance, whereas Michael explains „Continuous Integration with Golang and GitLab“. „Wie überwache ich eine Cluster-Applikation in Icinga 2?“, asked Daniel being at a customer – solving the problem with a little help from his friends. Eric explains „Filter for Multiple Group Memberships in SQL“, that will become even more powerful with the upcoming Icinga Web 2 release. In „Fresh from the shelfDavid reports about command-lines with Ranger, Progress and fzf, and Dirk inspired the Open Source Community about „Contributing as a Non-Developer“. One month, so much going on… Stay tuned!

Microsoft and GitHub – merge conflict?

For some time it has become clear that Microsoft is going to take over GitHub. As far as official sources can be trusted, GitHub will stay independent although a new CEO (Nat Friedman) will be introduced after the Microsoft takeover.

This question over GitHub’s future independence has raised a lot of skepticism within the developer community and many are considering moving their projects away from GitHub to a different location.

One alternative in this case could be GitLab. GitLab does not only have an online platform but it can as well be installed on your own hardware. Furthermore, it is an extremely solid piece of Open Source software you can fully rely on. This is also shown by the makers of GitLab themselves as they release updates each month – rolling out bug fixes, security updates and many recommendations regarding the use and configuration of your instance.

For those who would like to have their own GitLab instance, NETWAYS offers two options:

First one is available on our NETWAYS Web Services platform where we offer user-managed, hosted GitLab instances as Community or Enterprise Edition. The user does not need to take care of anything regarding installation or maintenance of his GitLab, but can directly go into production in no time with only a few steps needed. You as a customer are also free to decide for how long you would like to run your instances as any app is monthly callable. Furthermore, we regularly update these container based apps and monitor their health  for you. As a customer, you can register on NWS and try all the apps we offer 30 days for free.

The second product we offer is done by NETWAYS Managed Services which is exactly what it is called: With managed hosting you can get a virtual machine in our cloud or rented hardware running a full GitLab, either as Community or Enterprise Edition. You can choose the underlying ressources and we will do the rest for you, like installation with individual parameters and health monitoring. With managed hosting, our customers also have the choice to go full 24/7 support with “emergency” calls.

Releasing our Git and GitLab training as Open Source

Development is super fast these days, there are many tools and integrations to make it more comfortable. One of the version control systems is Git, next to well-known SVN and CVS. Git got really pushed by GitHub and most recently GitLab which provide entire collaboration suites. Nowadays you not only commit code revisions/diffs, you can also test and deployment changes immediately to see whether your code is good on defined platforms or breaks. Issue and project management is put on top and makes it very easy to collaborate.

Continuous integration (CI) allows for deeper code quality too. Add code coverage reports, unit test results, end2end tests and actually build distribution packages with tests on many platforms included. In addition to CI, continuous deployment (CD) adds the icing on the cake. Once CI tests and package builds are fine, add a new build job to your pipeline for automated deployments. This could for example push updated RPM packages for your repository and immediately install the bugfix release in production on all your client hosts with Puppet or Ansible.

You can do all of this with the ease of GitHub or your own hosted GitLab instance (try it out in NWS right now!). Don’t forget about the basics for development and devops workflows:

  • Untracked files, staging area, … what’s within the .git directory?
  • What is a “good commit“?
  • I want to create patch for an open source project – what’s a “pull request“?
  • Workflow with branches?
  • A developer asked me to “rebase your branch against master” and “squash the commits” … what’s that?

Our Git training sessions have been renewed into a two day hands-on session on Git and GitLab. Many of us are using Git on a daily basis at NETWAYS, in addition to GitLab. Knowledge which we share and improve upon. The training starts with the Git basics, diving into good commits, branching, remote repositories and even more. Day 1 also provides your own NWS hosted GitLab instance.

Starting with day 2, you’ll learn about development workflows with branches and real-life use cases. Continuing with CI/CD and generating your own Job pipeline, and exploring GitLab even further. We’ll also discuss integrations into modern development tools (Visual Studio, JetBrains, etc.) and have time to share experiences from daily work. I’ve been working with Git since the beginning of Icinga more than nine years ago.

We have open-sourced our GitLab training material. We truly believe in Open Source and want make it easier for development and contributions on your favourite OSS project, like Icinga.

You are welcome to use our training material for your own studies, especially if you are an open source developer who’s been learning to use Git, GitLab and GitHub. For offline convenience, the handouts, exercises and solutions are provided as PDF too.

Many of the mentioned practical examples and experiences are only available in our two day training sessions at NETWAYS so please consider getting a ticket. There’s also time for your own experience and ideas – the previous training sessions have shown that you can always learn something new about Git. You can see that in the Git repository and the newer Git commits, where this feedback was added to the training material ❤️

See you soon at the famous NETWAYS Kesselhaus for a deep-dive into Git and GitLab!

Ein Umzug von Wien nach Nürnberg mit der Vorliebe, österreichische Köstlichkeiten zu importieren - so mancher Kollege verzweifelt an den süchtig machenden Dragee-Keksi und der Linzer Torte. Oder schlicht am österreichischen Dialekt der gerne mit Thomas im Büro intensiviert wird ("Jo eh."). Wenn sich Michael mal nicht in der Community helfend meldet, arbeitet er am nächsten LEGO-Projekt oder geniesst das schöne Nürnberg mit #atasteofaustria 🙂

GitLab Security Update Reviewed

NETWAYS schreibt die Sicherheit ihrer gehosteten Kundenumgebungen groß – daher kamen auch wir nicht um das Sicherheitsupdate in den GitLab Community Edition und Enterprise Edition Versionen herum.

GitLab machte Mitte März öffentlich, dass man auf eine Sicherheitslücke sowohl in der Community als auch in der Enterprise Edition gestoßen sei. Dabei soll es sich um sogenannte Server Side Request Forgery (SSRF) handeln, was Angreifern unter anderem den Zugriff auf das lokale Netzwerk ermöglich kann. GitLab löste dieses Problem nun durch ein Software Update und den Einbau der Option “Allow requests to the local network from hooks and services“, die per default deaktiviert ist und somit den Zugriff der Software auf das lokale Netz unterbindet.

Das Update auf eine neuere Version ist für viele Nutzer eine gute Lösung – allerdings nur, wenn diese keine Webhooks oder Services, die das lokale Netz als Ziel haben, nutzen. Denn wenn plötzlich die Webhooks und Services nicht mehr funktionieren und weder der Admin noch der User weiß, dass man bei der obigen Option einen Haken setzen muss, dann beginnt erst mal die Fehlersuche.

Fazit: Wer unbedingt auf Webhooks und ähnliches angewiesen ist, muss wohl oder übel vorerst mit der Sicherheitslücke leben.

Eingebaut wurde der Fix in folgende GitLab CE und EE Versionen: 10.5.6 / 10.4.6 / 10.3.9. Eine vollständige Übersicht an Releases findet man hier: GitLab Release
