Back to a teach-myself-something type of project, with setting up K8s Cluster on Raspberry Pi devices. I had a couple of older Raspberry Pi 3s and a recently purchased Pi 4 available for this. My old Pi3 devices had Docker Swarm (yes that one) from a couple of years back. This time around I want to get k8s on the 3 Pi devices.
The steps are fairly simple but it can be a bit of work. You should find blogs out there with decent enough directions. So here goes me adding to that library of blogs to make it easier for the next person trying to set this up.
I have used (still use) a commercial VPN service (for those few occasions I am outside and need some extra security). But I have always wanted to standup my own VPN server to have a bit more confidence that my activity logs are not being watched (worse sold or hacked) by a 3rd party VPN provider. Punted this for a long time, but found the perfect opportunity to do that today while waiting for some car repairs at an auto service center.
Capturing metrics from your system is critical to understanding its internal behavior and to tune its performance. Without this you are operating in the blind. In this post we will go through how you can gather metrics from a Spring Boot application using Prometheus, Grafana and Micrometer.
There are multiple strategies you could use to introduce new service versions to an existing product. In this article I will go over how you can implement Canary deployments using Istio in a k82 cluster. The same approach can be used to implement Blue/Green deployments too.
You probably have heard leadership talk about Digital Transformation in meetings, town halls and blogs. Industry pundits seem to talk/write about it; often using it to rank which companies are competing at the topmost level in their industry. Often though there is confusion among the rank and file employees about this whole “Digital” thing. Is it the latest buzzword that executives are in love with (probably true to some extent)? Is there anything behind it or just a lot of hot air? Who are all those high priced management consultants that show up to tell us about Digital Transformation, without explaining what it is?
I will begin by saying ” DON’T EVER DO THIS IN THE REAL WORLD”. https://github.com/auchenberg/volkswagen will detect if your build is running inside a CI tool and then force all tests to pass; even if they fail. Now you know why I said “DON’T EVER DO THIS IN THE REAL WORLD”. Hey just having some fun … code quality purists you have been warned not to read further! 🙂
