Azure DevOps–Export wiki to PDF

If you ever want to export your Azure DevOps wiki, you can use the AzureDevOps.WikiPDFExport tool.

  • Start by cloning your Azure DevOps wiki to a local folder.

Troubleshooting

While executing the tool I encountered some issues so here are some troubleshooting tips.

Tip 1 – Ignore the Qt: Could not initialize OLE (error 80010106) warning

If you see a Qt: Could not initialize OLE (error 80010106) warning while executing the tool, don’t worry. You can just ignore this message.

Tip 2 – Be aware about the .order file

The first time I executed the tool only a few of my wiki pages were included. I found out that this was the case because when it detects a .order file it will only include the pages mentioned inside the .order file.

So make sure that all wiki pages are mentioned inside the .order file.

Tip 3 – Specify the ‘—attachments-path’ when your wiki pages include images

When trying to export a wiki page containing images it failed with the following error message:

C:\example\Docs>azuredevops-export-wiki

    WARN: Removing Table of contents [[_TOC_]] from pdf

ERR: Something bad happend.

System.ArgumentNullException: Value cannot be null. (Parameter 'path1')

   at System.IO.Path.Combine(String path1, String path2)

   at azuredevops_export_wiki.WikiPDFExporter.CorrectLinksAndImages(MarkdownObject document, FileInfo file, MarkdownFile mf) in D:\Git\WikiPDFExport\AzureDevOps.WikiPDFExport\WikiPDFExporter.cs:line 674

   at azuredevops_export_wiki.WikiPDFExporter.ConvertMarkdownToHTML(List`1 files) in D:\Git\WikiPDFExport\AzureDevOps.WikiPDFExport\WikiPDFExporter.cs:line 497

   at azuredevops_export_wiki.WikiPDFExporter.Export() in D:\Git\WikiPDFExport\AzureDevOps.WikiPDFExport\WikiPDFExporter.cs:line 149

To fix this error I had to include the ‘--attachments-path’ option and explicitly specify the location of the images:

C:\example\Docs>azuredevops-export-wiki --attachments-path C:\example\Docs\.attachments

Tip 4 – Use the –h option for a good TOC

The tool doesn’t support the TOC (Table of Contents) tag and will be removed from the pdf. As a workaround you can use the ‘-h’ option to create a heading for every wiki page in the PDF file. This doesn’t replace this feature but already helps to make your PDF more accessible.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...
