Local Cluster for Personal Projects

I’ve been trying to figure out a simple way to have a CI/CD pipeline for my personal projects. I’ve tried several options but was never happy with anything. The last attempt is to use a local microk8s cluster with production ready configuration and certificate management so I can easily deploy any project to the cluster without much work. This is the setup I ended up with.

There are 3 main pieces to this: Github actions, a docker registry and the kubernetes cluster itself.

On a home server I’m running a docker registry only accessible through the local network and also a github actions runner.

On the same server I’m running a single node microk8s cluster with the following addons:

Slack Interaction Routing using Django resolvers

Developing a integration for Slack is not easy task. Slack’s API is pretty great and allows a lot of freedom. But when you start adding buttons, integrations and, more recently, interactions with blocks your code will quickly become a never-ending list of if/the/else clauses.

While developing integrations the new slack interactions we were writing were becoming unmangeable. For every new button there would be a new if block_id == "feedback-button" so new solutions needed to be found.

The best one was using Django’s routing mechanism to treat the interactions as urls on a website. Once this mindset was introduced everything became much easier. Let’s start with some examples. First the main methods that make this possible:

def slack_resolver(url: str) -> ResolverMatch:
for urlconf in settings.SLACK_URLCONFS:
# try the various urlconf files we have
resolver = resolve(url, urlconf=urlconf)
return resolver
except Resolver404:
raise Resolver404()

def slack_reverse(viewname, args=None, kwargs=None):
for urlconf in settings.SLACK_URLCONFS:
return reverse(viewname, urlconf=urlconf, args=args, kwargs=kwargs)
except NoReverseMatch:
raise NoReverseMatch(f"Reverse for {viewname} not found: args: {args}, kwargs: {kwargs}")

As the method signatures show the slack_resolver method receives the current url being processed and return the resolver to call the view’s function.

Astral Chain

I’ve been postponing playing this game for a long time. Being a father of a 2 year old and having my own company doesn’t allow a lot of time for JRPG’s. But I couldn’t resist much more. I love the style of this game. And honestly it touches on everything I love on JRPG’s, demon-like robots (Legions), great story (a bit convoluted, but I love those), fresh mechanics that make fighting super fun and quirky characters that give life to the world that was created.

As far as JPRG’s go this one changed the formula a bit because you have levels (chapters). Progress is done by missions and not a free flowing experience like normal JPRG’s (like Final Fantasies). I liked this approach a lot because it focuses your time and doesn’t make you grind and spend endless hours just to get somewhere.

Definitely a game to go on the excelent experiences list.
