3 Virtual Machines Kubernetes cluster

Dependencies

You should install VirtualBox and Vagrant before you start.

Creating the cluster

You should create a Vagrantfile in an empty directory with the following content:

curl -s -k \
  --cert ~/.minikube/client.p12 \
  --key  ~/.minikube/client.key \
  --pass tcuser \
  https://192.168.64.8:8443/api/v1/pods \
    |jq '.items[].metadata.name'

$JobsToCopy = Get-DbaAgentJob -SqlInstance $OldInstance -ExcludeDisabledJobs;

# Copy the Operator(s) from the existing server

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

1. Install the VirtualBox package (this might be different for your platform).

Feedback

I'm sure I've gotten multiple things wrong here. Either flat out wrong, anti-patterns or just sub-optimal. I'm new to prometheus, grafana and mtail...so please feel free to share corrections/suggestions.

Background

There are a handful of custom nginx stats exporters.

Some are tying into internal nginx stats like the official nginx exporter: nginx-prometheus-exporter
