The reason for dockerizing LinkChecker is to facilitate Praqma’s Gijeli set-up and produce reports for web projects. There are other Docker images of LinkChecker out there, but we find them lacking when it comes to entertaining stable automated builds.
Any change applied to the image will trigger a new Jenkins job and the build process will tag each release with a version number.
GiJeli is a word made up as a contraction of
All versions will be available at Praqma’s Docker Hub.
docker pull praqma/linkchecker:v[version number]
linux / iOS:
docker run -v $(pwd):/data praqma/linkchecker:v[version number] [Options] [Output Options] [URL]
docker run -v /$(pwd):\\data praqma/linkchecker:v[version number] [Options] [Output Options] [URL]
Using the LinkChecker Docker image we want to produce a report for http://www.yourURL.com/ in CSV format named linkchecker.report.csv and place it in /your-project/your-report-folder/. To achieve this, the following steps will be taken:
mkdir -p -m 777 your-report-folder
docker run -v $(pwd):/data praqma/linkchecker:v1 --check-css --check-html --complete --anchors -F=csv/your-report-folder/linkchecker.report.csv http://www.yourURL.com/
Have a cup of coffee or tea while you wait for your report to be generated. We are using Jenkins jobs to automate report production for our jekyll web projects. Don’t forget to read our extra article for a deeper dive into generating and publishing LinkChecker reports.

In this blog I will show you how to create snapshots of Persistent volumes in Kubernetes clusters and restore them again by only talking to the api server. This can be useful for either backups or when scaling stateful applications that need “startup data”.

When I read Fowler’s new ‘Refactoring’ book I felt sure the example from the first chapter would make a good Code Kata. However, he didn’t include the code for the test cases. I can fix that!

Nicole Forsgren and the Accelerate DORA team has just released the newest iteration of the State of DevOps report. The report investigates what practices make us better at delivering valuable software to our users as measured by business outcomes. Read on for our analysis of the report, and how it can be best put to use.
The latest drivers of software delivery performance
A major challenge of software development is that our work is by and large invisible. This makes our folklore essential in business matters. Some of our commonly used arguments and visualizations are digital urban legends rather than solid foundations for informed decisions. Here, we’ll go through a few examples and some measures to address our misconceptions.
How the stories we tell influence our decisions
When you embark on your cloud native journey there will be important choices to make about cloud providers, continuous deployment, environments’ setup and separation. This guide will help you make the right choices by sharing lessons learnt from running cloud native apps in production.
Kubernetes has become the de facto container orchestration platform. When we help clients of different sizes and domains start their cloud native journeys in Kubernetes, we assist them in making sound decisions and technology choices. There is no one-size-fits-all solution when it comes to choosing cloud providers, CI tools, continuous deployment pipelines etc., so it is important to make the right decisions at the start. Failing to do so can be very costly in terms of lost time and money.
How to make the right technical choices on your cloud native journey
Learn how Docker and Kubernetes work and the key benefits they bring. Using real demos, I show how Docker is a great packaging and distribution technology, and how Kubernetes provides a powerful runtime for containerized applications.

In the world of Agile and DevOps we use many figures, charts and diagrams to argue and reason about our world and how we prioritize and make choices. However, at all levels of the organization, we misuse and misinterpret figures. It’s time to be explicit, measure the right things and act on them. Watch this talk from DevOpsDays Zurich in May 2019.
