#^SPIFFE – Secure Production Identity Framework for Everyone

Secure Production Identity Framework for Everyone Inspired by the production infrastructure of Google and others, SPIFFE is a set of open-source standards for securely identifying software systems in dynamic and heterogeneous environments.

What is SPIFFE?
SPIFFE, the Secure Production Identity Framework For Everyone, provides a secure identity, in the form of a specially crafted X.509 certificate, to every workload in a modern production environment. SPIFFE removes the need for application-level authentication and complex network-level ACL configuration.

#^Running Jenkins Files inside GitLab CI

Learn how to lift and shift your Jenkins jobs over to GitLab CI while you migrate.

First, I want to set some ground rules for this. For starters, this process is not meant for long term use. There are many downsides to this - Such as it only runs in one GitLab Stage and isn’t asyncronous. However this process can be used to run your Jenkins builds in GitLab CI, While you’re migrating your Jenkinsfile to GitLab CI Syntax. Make no mistake - This doesn’t solve your migration woes, But it does allow you to run your Jenkinsfile inside GitLab for the time being. It’s a stop-gap measure.

Interesting talk from #OSMC about micro-perimeter, least privileges, zero trust architectures, etc.

#^Kata Containers isolieren Workloads von Docker und Kubernetes - Aus Linux-Magazin 12/2018

#^Zentrales Logging mit dem Elastic Stack
on media.ccc.de

Dezentrales Logging wird mit der steigenden Zahl von zu überwachenden Prozessen immer aufwändiger. Deshalb gibt es seit mehreren Jahren Tools welche das Zentrale Logging unterstützen. In diesem Vortrag soll der Elastic Stack als ein solches Tool vorgestellt werden.

In der Welt der Microservices ist die Anzahl der Logs-produzierenden Prozesse sehr groß und liegt durchaus im Bereich von 100-1000 Prozessen. Eine manuelle Log-Verarbeitung ist hier so gut wie undenkbar. Doch auch monolithische Services laufen oftmals dezentral und das Analysieren der Produktions-Logs ist dann häufig auch mit viel Aufwand verbunden. Mithilfe eines zentralen Loggins lässt sich eine viel bessere Übersicht über den Gesamtzustand eines Systems gewinnen, da nicht jedes Log einzeln untersucht werden muss, sondern die Logs aggregiert und somit auch leicht automatisiert ausgewertet werden können. Der Elastic-Stack bietet die Möglichkeit, große Mengen an Logs zu speichern und zu durchsuchen. Das Ökosystem um den ELK-Stack unterstützt Entwickler, DevOps usw. dabei, die Logs schnell und einfach aufzubereiten, damit diese gut analysierbar sind. In diesem Vortrag werden die Vor- und Nachteile des zentralen Loggins dargelegt und gezeigt, wie sich der Elastic Stack in Umgebungen einbinden lässt.

#^SQL is No Excuse to Avoid DevOps - ACM Queue

A friend recently said to me, "We can't do DevOps, we use a SQL database." I nearly fell off my chair. Such a statement is wrong on many levels.
"But you don't understand our situation!" he rebuffed. "DevOps means we'll be deploying new releases of our software more frequently! We can barely handle deployments now and we only do it a few times a year!"
I asked him about his current deployment process.

#^Trunk Based Development - Game Changers

Since the early 80’s a number of things have pushed best practices towards Trunk-Based Development, or away from it.

The language in use to describe such things has changed over time. Software Configuration Management (SCM) is used less today than Version Control Systems (VCS) is. A simpler still term - “Source Control” - seems to be used more recently, too.

Similarly, ‘trunk’ and ‘branch’, have not always been used as terms for controlled code lines that have a common ancestor, and are eminently (and repeatably) mergeable.

#^Safe Containers » ADMIN Magazine

By Martin Loschwitz
Docker containers are a convenient way to run almost any service, but admins need to be aware of the need to address some important security issues.
Container systems like Docker are a powerful tool for system administrators, but Docker poses some security issues you won't face with a conventional virtual machine (VM) environment. For example, containers have direct access to directories such as /proc, /dev, or /sys, which increases the risk of intrusion. This article offers some tips on how you can enhance the security of your Docker environment.

I already had a dockerized Selenium-Grid but it was a good idea to replace it with Selenoid. The state of automation and the video recording feature are really impressive.

#^Selenoid

Selenoid is a powerful implementation of Selenium hub using Docker containers to launch browsers.

Lightweight and Lightning Fast
Suitable for personal usage and in big clusters:
* Consumes 10 times less memory than Java-based Selenium server under the same load
* Small 7 Mb binary with no external dependencies (no need to install Java)
* Browser consumption API working out of the box
* Ability to send browser logs to centralized log storage (e.g. to the ELK-stack)
* Fully isolated and reproducible environment

#^RDBMS Containers » ADMIN Magazine

If you spend very much of your time pushing containerized services from server to server, you might be asking yourself: Why not databases, as well? We describe the status quo for RDBMS containers.

There will be beta-exams for the new LPIC-OT at FrOSCon in August. Looking at the objectives for this new exam it contains a lot of what I have done recently.

#^DevOps Tools Engineer

DevOps is one of the most in-demand skills in open source today.  In order to meet this need with verified skills LPI, an established authority in Linux Administration, is developing the DevOps Tools Engineer certification.  These additional certified competencies strengthen the portfolio of today’s IT professionals.

As more and more companies introduce DevOps methodologies to their workflows; skills in using tools which support the collaboration model of DevOps become increasingly important. LPIC-OT DevOps Tools Engineers will be able to efficiently implement a workflow and to optimize their daily administration and development tasks.

This certification will be released in autumn 2017 and will test proficiency in the most relevant free and open source tools used to implement the DevOps collaboration model, like for example configuration automation or container virtualization.

The new certification is created according to LPI‘s community-based certification development process. This process relies heavily on involvement by the IT community.

Secure Your Containers with this One Weird Trick

Did you know there is an option to drop Linux capabilities in Docker? Using the docker run --cap-drop option, you can lock down root in a container so that it has limited access within the container. Sadly, almost no one ever tightens the security on a container or anywhere else.

Nice!
