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…
Previously I had installed wordpress pods on Kubernetes and it made it very easy to administer and add multiple sites for clients. However, as time went on they started getting more aggressive in the different themes they were uploading. To solve the problem required configuration changes in two places. The Ingress Controller The PHP file…
As I’ve been dealing with streaming data one of the architectural decisions I’ve had to make is how to run periodic batch jobs on the data as it comes in. In the case of web traffic, it is logged into a database. What my batch jobs do is take the data from the MariaDB MySQL…
While looking for different options on how to run an ingress controller on AWS I found that EKS recently announced support for an open source project that creates an ALB ingress controller. One of the advantages of an ingress rule is that I can have many services be reachable via one external load balancer. In…
Today we had to work on switching between two kubernetes clusters. The commands of the day are:
|
1 2 |
kubectl config get-contexts kubectl config use-context <context> |
It’s surprisingly not so simple. Perhaps there are tools out there that people know of to make it easier? What I’ve been doing is taking to ~/.kube/config files and concatenating them together. As an example, my config…
Lately I came across a few bare metal servers in our lab and decided I would test some of my ideas on setting up a bare metal kubernetes cluster on these nodes. I started thinking that if I were to do so I would need some persistent storage. There were a few options I could…
Terraform has some good ways to do interpolation that can be simple. However, I think as I’ve tried to make Terraform do more of what Ansible does, which might be outside its scope, I run into issues. One issue I had was creating a list of all the servers in the cluster that I wanted…
The Kubernetes 1.0 launch happened July 21st at OSCON here in Portland, OR and I was super happy to be there in the back of the room picking up loads of free stickers while the big event happened. I spent the day before at a Kubernetes bootcamp, which was really just a lab on using…
