Writing BPMN Let's Encrypt Kubernetes Operators in Python II

As I already mentioned, I wasn't too happy about the currently available DNS operators out there that integrate with let's encrypt. What I wanted was one that works right of the box, and allows me to add new Ingress objects, and magically generate their TLS certificates. I'm going to break down in a small mini-series of articles on how I ended up implementing it.

Using Boundary Timer Events in Adhesive BPMN

When having a critical long running task, it's imperative we get immediate feedback on things that run longer than they are allowed. With the new Timer boundary events, that's trivial to model.

Containerizing the Build Process

Having the adhesive build process as code it's a nice feature to have. In combination with containers it makes the source code the only truth on how the build is being performed. But that still means we have a dependency now on the build system itself. So how do we get rid of it? We're going to containerize the local build system.

Event Deduplication in BPMN

When ingesting a lot of events it makes sense to process only the last relevant event from the received events, and discard the previous ones. Since BMPN already works with execution tokens, which are in themselves events, how can we drop duplicated events?

Creating REST Endpoints Using BPMN Messages in Python

Sometimes we just want to process events that arrive from an outside system, but still model these in an BPMN process. BPMN natively supports that representation in the form of input messages starting events. We'll be wiring Flask to stream messages directly into the process using the message_calback function.

Creating a New Python BPMN Process With Adhesive

BPMN is great. We draw what we want to execute, and the engine takes care about the parallelism parts. We visually represent how the parts of the program are wired. With adhesive, we take it one step further and instantly implement the backing process. So let's start designing!

How to Automatically Upload Public Ssh Keys to Hosts

Whenever a new server needs to be managed, the first task is to upload my public key on that system, so I don't need to ever remember the password again, and use it again. Here's how I automated that process.
