I rarely go to Walmart and I definitely never thought I’d be going to Walmart for technology tools, advice, etc. However, thanks to Aymen EL Amri’s great curated weekly email, Kaptain, on all things Kubernetes, see https://www.faun.dev/, I ran across a great tool from Walmart Labs called Kubeman. If you are managing multiple Kubernetes clusters, and that’s almost always the case if you’re using Kubernetes, Kubeman is a tool you need to consider for troubleshooting. In addition to making it easier to investigate issues across multiple Kubernetes clusters, it understands an Istio service mesh as well.
I have been working with a client recently on getting Tomcat access and error logs from Kubernetes pods into Elasticsearch and visible in Kibana. As I started to look at the problem and saw Elastic Stack 7.5.0 released, it also seemed like a good idea to move them up to the latest release. And, now that Helm 3 has been released and no longer requires Tiller, using the Elastic Stack Kubernetes Helm Charts to manage their installs made a lot of sense.

I’ve recently been working on a new web portal and ran into a problem of trying to figure out how to dynamically configure the reCaptcha site key.
It is a basic single page application (SPA) utilizing the Angular web framework (with component based development) written using Typescript (love it!) and decorated using Bootstrap CSS (can’t live without it!). The frontend Angular application is served up from the backend Java SpringBoot. application And, the whole thing is deploy in Docker containers to a Docker Swarm cluster.
