This week, I attended a new kind of conferencecalled DevOps Essentials organized by dpunkt, heise Developer and iX. They decided to have most half-day workshops with only one keynote-like talk per day. I was able to contribute one of the half-day workshops for advanced users of Docker.
Products for continuous integration and continuous delivery have become a commodity. But among them is a growing number isolating build steps in containers. Instead of using a fully integrated product, I have created a tool called insulatr to execute builds in containers without the need for a server component or scheduler.
This week I had the opportunity to speak at the Azure and .NET Meetup Freiburg about developing PowerShell modules. Thanks for having me!
After one whole year, I was finally able to contribute another talk at DevMeetup Freiburg. It was about the security ups and downs of container management based on Docker.
ContainerConf marked a very special moment this year because I was able to contribute one workshop and two talks about Docker.
Publishing the Docker daemon usually involves creating the requires certificates, reconfiguring the Docker daemon and restarting it. But often, you do not have the necessary permissions to change the daemon configuration or restart it. I’ll demonstrate how to use a containerized reverse proxy to achieve the same.
This year, I co-organized x-celerate conference for the second time and contributed a half-day workshop about CI/CD for containers.
During my investigation regarding the merging of layers from multiple images, I realized that the Docker Registry API can also be used to tag image without pulling and pushing the whole image. Let’s take a closer look.
In my last post, I explained how to create Docker images from the layers of other images. As this is a rather complex process, I have published a PowerShell module to automate this.
Everyone is trying really hard to separate functionality in their Docker images. But we all have one or more images which contain multiple tools and take quiet some time to build. Unfortunately a rebuild will be necessary whenever a small change was made to the Dockerfile. This post will demonstrate how to conditionally build sections of a Dockerfile to reduce the build time.
