Notes on Chocolatey

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.

Hubot testing revisited

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 But as that test package is no longer maintained / updated, I wanted to switch to something that is more in line with what Hubot itself does: hubot-mock-adapter.

A Dev Container for Bot Zero

Let’s explore how to add a dev container to our Node.js bot-zero project. We’ll help the end user to understand how to run the project by adding a profile script whenever the terminal is openend in Visual Studio Code.

Harmonizing Team tags on AWS S3 Buckets

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.

Share AWS Vault session with Bash (WSL)

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…

Expose a Docker Compose App with a Secure Cloudflare Tunnel

Expose a Docker Compose application through an outbound-only Cloudflare Tunnel, without publishing host ports or managing a reverse proxy and TLS certificates.

Chrome Extension Development: Fetch non CORS URLs in v3

Testing whether a URL exists on GitHub by delegating fetch to a service worker.

App definitions from Mesos/Marathon to CSV

We’re currently in the business of moving from Mesos/Marathon to Kubernetes. As we have a microservices environment we can move service by service. We have multiple clusters running, so I need to track which teams have which services (still) running on Mesos/Marathon.

Let’s see if we can lift the data out of the system using the Marathon API, JQ and cURL.

Bash Script with a Library for Named Arguments

Move reusable Bash named-argument parsing into a sourced library while keeping validation and supported options under the caller’s control.

Grafana, I want slugs back for my Hubot! 😭

At Wehkamp, we use the Hubot Grafana project to make our Grafana dashboard available in Slack. It mainly helps our standby team to make quick assessments on what’s going on with our website. Last year, we saw we could not upgrade the package from 2.5.2 to 3.0.1, because slugs could not be used anymore. But we use slugs and… quite heavily! So we did not upgrade our Grafana v7… until we got hit by the input field bug. We decided to see what we could do to bring our slug feature back to our ChatOps bot!
