Return to Kumotori

While other countries have pretty harsh lockdown rules (from what I hear on the news), Japan is pretty lax about that. While commuting to work by train is discouraged, I figured going up in the mountains (where there are hardly any people) it can’t hurt, right?


Training for Aconcagua

After Elbrus and Kilimanjaro, I knew I can’t take Aconcagua lightly. At almost 7000m it’s the highest mountain outside of Asia and thus the second highest of the Seven Summits. Working full time, the time I had available for training was very limited. This was before covid hit either, so I actually had to commute to the office too, which is about an hour one way. So what can the man do if he only has so many hours in the day and he needs some sleep too, but training has to be done for Aconcagua?


Tanigawa-dake

If you’ve watched Yama no Susume, then you’ve heard of Mt Tanigawa. It’s the goal of a major arc of the story and an important memory to the characters. I went there in a different season though (in the snow), but didn’t climb the main summit. For no particular reason other than I didn’t realize the summit I was at wasn’t the highest point. Whoops.


2019 in review

This year was quite thick in events so I decided to write a year retrospect for a change. I read somewhere that people tend to do wild things when they’re nearing a “round” age like 30, except I read about this after I planned most of the stuff listed below… It definitely did turn into a very eventful 30th.


ArgoCD bootstrap cluster

I wish it could be completely automated… But for now I’ve just automated as much as possible (and convenient). The ingredients:

  • Helm
  • Sealed Secrets
  • Argo CD and Argo Rollouts
  • traefik
  • Prometheus and Grafana

I have a repository for the purposes of playing around with Kubernetes tooling like this – and hopefully turn it into an actual application eventually. I have big plans and lots of stuff I want to try out, but time is limited. All the code examples in this post use the namespaces and naming choices in the repository. The folder structure (relevant to this bit) is like…

system
 ├┬ apps
 │└─ (bootstrapped Argo CD app manifests)
 ├┬ argo
 │└─ the local "umbrella chart" for Argo CD and Argo Rollouts
 ├┬ bootstrap
 │└─ boilerplate project and application manifests
 └┬ manifests
  └─ manifests I didn't bother turning into a Helm chart
     referenced by the raw-manifests.yaml application

Collapse of the docker0 bridge

We’ve got a printer in the office. I’m not sure how the network is organized, but it’s on a different IP range than the rest of the dev network. And for some reason I couldn’t get it to work.


Mitake & Otake

Mitake with its ropeway is probably “the” hiking destination in Tokyo. It’s accessible, not particularly high and you still get beautiful views. Oh, and crowds. Of course crowds.


Telegraf on Kubernetes with InfluxDB Cloud

I’ve had most of my stuff running a k3s “cluster” for the past half a year or so. The whole setup runs on a single $5-a-month Digital Ocean droplet with 1vCPU and 1GB of memory.

Needless to say, it doesn’t take much to bring the whole thing to its knees. While it has no issues dealing with the little traffic my blog receives, I would accidentally bring it down occasionally when I install a Helm chart that turned out to be much heavier than I’d thought.


Amagi

Not the carrier. Not the anime. The mountain. (After which the carrier was named, by the way.) It’s not one of those jagged, snow-capped “cool” mountains. It’s a relaxed, even comfy mountain. At 1400-and-a-little meters high with gentle slopes, it’s a good day’s escape from Tokyo’s chaos.


Hacktoberfest

After last year, I once again decided to take part in the Hacktoberfest fun. I have plenty of repositories lying around (sadly much less well maintained by yours truly than preferable). Of course this also means that I can gather the necessary contributions from updating dependencies in my own repositories, but I’d prefer to instead contribute to those dependencies.
