Containers

Endocode's 2016

We’re almost done with 2016 and while on a global scale, this year has been a bit rocky, we have various reasons to look back and be proud of what we have achieved. We have been contributing to Open Source projects: to ConnMan, to systemd, to fleet, to Kubernetes, to the NGINX Ingress Controller, to ofono, to python-oca, to skydns, to the Mattermost LDAP Plugin and a few more. Oh and we also created a tool to create, update and rollout Kubernetes resource yamls from a template.

Endocode and all that Buzz

cc-by-sa 3.0 Thomas Wegner/Berlin Buzzwords (no changes made)   Last week was a busy week. Endocode was spread out across Europe, listening and contributing to the newest buzz. While some of our team were in Amsterdam at the GCP Next, finding out what’s new in Kubernetes 1.3, Endocode’s Thomas Fricke was contributing at the Berlin Buzzwords. It was the seventh time that the Berlin Buzzwords brought interesting and inspiring people together, to listen to keynotes and talks, ask questions and discuss ideas and experiences.

What we did @cfgmgmtcamp 2016

In our world of DevOps and Open Source, February is a month to look forward to. Like a fusion of Christmas and Easter, FOSDEM and Config Management Camp bring together developers of free and Open Source software and create a feast of conversation, contribution and fantastic meetings. Endocode’s Sebastian Sucker, Matthias Schmitz and Julian Strobl took a little trip to Belgium this year and enjoyed the wonders that could be found at Config Management Camp 2016 in Gent.

Linux containers and user namespaces – Part 2

    In our last blog post we gave you a short introduction to Linux namespaces. Part 2 will go deeper into user namespaces and current problems that Linux containers face today. Among them, resource accounting and container privileges are top culprits. Currently, processes on the host may still share some resource accounting within processes inside containers. The question of how many processes the same user and owner of containers must have is one of the many examples.

Linux containers and user namespaces – Part 1

    Containers are lightweight virtualization tools that give the illusion of separation and isolation to processes. They are not a security technology, but they do offer some isolation like filesystem operations and network operations, using Linux namespaces. However, as more containers are deployed we continue to find problems that need to be addressed. Among them, resource accounting and container privileges are top culprits. For now we will give you a quick overview over Linux namespaces.

Building a stream processing pipeline with Kafka, Storm and Cassandra – Part 3: Using CoreOS

In part 2 of this series, we learned about Docker and how you can use it to deploy the individual components of a stream processing pipeline by containerizing them. In the process, we also saw that it is can get a little complicated. This part will show how to tie all the components together using CoreOS. We already introduced CoreOS in part 1 of this series, so go back and take a look if you need to familiarize yourself.
