A Simple and Portable Dockerfile for Working with Azure and Ansible
For our use case, we need to be able to deploy Azure machines using Ansible from developer’s laptops and from our own CI/CD infrastructure both on Jenkins and OpenShift. The easiest way to ship a working and easy-to-use environment for our use case is to create a Docker instance: we based our Docker on rockylinux…
Read MoreMy OpenShift Journey #5: Run Unprivileged Containers with systemd in OpenShift: Part 2 – Testing
In my previous blog post, we modified the boot parameters to enable cgroups v2 and the user namespace in CRI-O. In this second part I’ll show you how to run a sample container with systemd and check that the modifications we made actually worked. Setting up a Test Docker To test the new config, let’s…
Read MoreMy OpenShift Journey #4: Run Unprivileged Containers with systemd in OpenShift: Part 1 – Deployment
For our ongoing transition from Jenkins to OpenShift, we’re currently working on porting our testing infrastructure to OpenShift. Our tests involve installing and running our product, NetEye, in a container. The installation requires a working systemd environment inside the container, and systemd needs to run with PID 1 and as root user (UID 0). Until…

In a previous blogpost, we showed how to test an ISO using Packer, an open source software tool for creating machine images for multiple platforms. One of the issues we faced was due to a security requirement we have: that the ISO we ship must have its password already expired so that when NetEye is…
Read MoreHow to Use a Host’s Redhat Subscription to Run Containers Using Docker instead of Podman
In NetEye 4.23 we shifted our base containers from CentOS to RedHat Enterprise Linux. Within our NetEye image and container we ship packages that come from RedHat Enterprise Linux’s private repositories and are thus subject to subscription, hence we need a way to be able to use our subscription when building NetEye containers. RedHat allows…

In the world of IT monitoring, we often deal with metrics that are cumulative, or where we cannot control or modify the definition of a metric. Examples include the various Windows performance monitoring metrics for MS Dynamics AX 2013 R3 (AOS) server. These metrics are cumulative, but whenever the AOS services are restarted, or the…
Read MoreContinuous Deployment for Grafana Dashboards using Jsonnet and Jenkins, Part 2
In my previous blog post, I introduced our scenario: in a private cloud context, we want to deploy a dashboard for multiple clients created using Grafana, InfluxDB and Telegraf for SQL performance monitoring. We saw how to write a Grafana dashboard programmatically using Jsonnet and upload it to Grafana using the Grafana API. In this…
Read MoreContinuous Deployment of Grafana Dashboards Using Jsonnet and Jenkins, Part 1
Say we want to monitor the disk latency of SQL Servers or other Windows Performance Counters in a private cloud context, and plot the results for users of our performance management platform who likely work in different companies. InfluxDB, Telegraf and Grafana are the right tools to achieve this, and with the power of Flux,…
