  • Docker, block I/O and the black hole
    von Mario Kleinsasser am 30. September 2018 um 8:47

    Last week, Bernhard and I had to investigate high disk I/O load reported by one of our storage colleagues on our NFS server which serves the data for our Docker containers. We still have high disk load, because we are running lots of containers and therefore this post is will not resolve a load issue […]

  • Writing a Docker Volume Plugin for CephFS
    von Mario Kleinsasser am 6. September 2018 um 9:25

    Currently we are evaluating Ceph for our Docker/Kubernetes on-premise cluster for persistent volume storage. Kubernetes officially supports CephRBD and CephFS as storage volume driver. Docker does not offer a Docker Volume plugin for CephFS currently. But there are some plugins available online. A Google search comes up with a handful plugins that supports the CephFS […]

  • Docker Swarm Network – Down the Rabbit Hole
    von Mario Kleinsasser am 4. September 2018 um 6:45

    Last week we tracked down a recurring problem with our Docker Swarm, more exactly with the Docker overlay network. To anticipate it, there is a merge which might fix this, but not for Docker-CE 18.03 . The pull mentioned is also not included in Docker-CE 18.06.1 but it is already merged into Moby and part […]

  • Testing Remote TCP/IP Connectivity – IBM i (AS400)
    von Markus Neuhold am 8. August 2018 um 13:59

    Preface I’m used to run telnet to do a quick check if a remote server is reachable and listening on a specific port. When trying this on i5/OS with telnet CMD you may get headache! After some research I ended up with openssl in PASE to succeed my task on IBM i (AS400). telnet vs openssl […]

  • Kubernetes the roguelike way
    von Mario Kleinsasser am 21. Juni 2018 um 17:15

    It has been a while since the last post, but we had a busy time. Together with my colleagues I wrote a large documentation called Kubernetes the roguelike way over the last few weeks. The documentation is about our setup of Kubernetes which we use on premise. We will continue the documentation as we are […]

  • Speaker at DevOps Gathering 2018
    von Mario Kleinsasser am 24. Februar 2018 um 14:24

    This year and for the first time I attended as speaker at the DevOps Gathering 2018 conference at Bochum Germany! Long story short, it was an extremely great experience for me! The idea for giving this talk was born in October 2017. I knew that Peter Rossback (a long term friend of us) invented a […]

  • Terraform(ing) Blue-Green Swarms of Docker (VMware vCenter)
    von Mario Kleinsasser am 21. Januar 2018 um 15:03

    Preface Terraform(ing) Blue-Green Swarms of Docker will enable you to update your Docker Swarm hosts to the actual Docker-CE version without an outage. For example imagine the following situation. Your have some Docker Swarm manager up and running and of course a bunch of Docker Swarm workers. If you are forced to update your operating […]

  • Terraform(ing) Docker hosts with LinuxKit on-premise (VMware vCenter)
    von Mario Kleinsasser am 13. Januar 2018 um 10:20

    Preface This blog post aims not be a fully-fledged step by step tutorial on how you can create and bootstrap a Docker Swarm cluster with VMware vCenter on-premise. Instead, it should give you an idea about what is possible and why we do it this way. There are different ways to achieve different goals and […]
