We 🧡 the combination of Grafana, Hubot & Slack. We use it all the time to visualize dashboards in Slack. But the interaction with certain dashboards might not be as fast as one expect from a chat bot, so let’s see what we can do.

With the Chocolatey Package Manager for Windows, it is super easy to install software from the command-line. This makes your installs scriptable and thus repeatable. In this blog I’ll show you how to render installation instructions from a machine and how to use the Windows Task Scheduler to update your packages regularly.

So far I’ve been using the hubot-pretend package for the testing of the hubot-command-mapper. But as that test package is no longer maintained / updated, I wanted to switch to something that is more in line with what Hubot itself does: hubot-mock-adapter.

In this blog we’ll explore how to combine GitHub, git, SSH, GPG and DevContainers on Windows in such a way that we can interact with GitHub from our DevContainer just as we would from our dev box. We’ll use our bot-zero project as an example.

At Wehkamp we use many – many – buckets! To do FinOps correctly, it is important we’re able to determine which teams own which buckets. In this article I’ll discuss how to detect Team tags that are not correct and apply the correct ones. We’re using a combination of Bash, AWS CLI, CSV and JQ.

At Wehkamp we’ve been using ASP.NET for a long time. Containers brought .NET with us to our microservices architecture. We used a shell script in a special build container to build our service. Today we’ll discuss how we turned that shell script into a multi stage build Dockerfile. Goals With the new setup we have […]

I’m on Windows and I use AWS Vault to connect to AWS using an MFA token. It works wonderfully, unless you need to execute some Bash scripts. I love using Bash on Windows, as WSL makes it really easy to write my scripts. But, alas, the AWS environment variables set by AWS Vault are not […]

When I build containerized apps that need to be exposed on the internet, I usually need to forward ports, set up let’s encrypt and reverse proxy some random port. In this blog I’ll show you how to ditch all of that in favor of 1 secure Cloudflare tunnel in a docker-compose file.
