In another installment of stupid Kubernetes routing tricks I bring you the following problem: So I figured the thing to do is to just use Kubernetes as a reverse proxy to send traffic to Webflow. So that’s what I did. I broke this up into two different sections. First, let’s tackle the webflow issue. This…
We have a couple of pods that get pretty intense memory use. It’s possible there is a memory leak because it OOM’d a node due to a spike in usage. One of our temporary solutions while we investigate is to put a pod anti-affinity rule in the deployment. What this means is that we don’t…
I’ve always stressed that it should never be Kubernetes or Serverless, but rather: What is the right tool for the job. Both technologies are great and both technologies carry their own baggage. This week as I was working on some design and thought about its implementation I had to decide whether I should add a…
This is a pretty confusing title but the gist of it is this: We have a service, let’s suppose its a database, running internally. We can get to it from our Kubernetes cluster, but resources outside of Kubernetes can’t get to it. And the only way we can get to Kubernetes services is through a…
Prometheus is confusing. It’s such a great project and there is all kinds of information out there, but it’s taken me a bit of legwork to understand it. The first issue is: How are you going to install it? Since I’m running this on Kubernetes it makes sense to use whatever most people are doing….
Lens is a really cool front end dashboard for Kubernetes clusters. One issue I ran into from connecting to the cluster was that I typically use different AWS Profiles for different clusters. Typically I’ll do something like: To set my user. To put this in Lens so that it can connect, we just add this…
I have an application that runs in a container. The application is pretty simple in that all it does is list the contents of a DynamoDB database I created. The code is here, as well as all the YAML files for deploying to EKS. The problem is, when we pull this up on a standard…
