Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Loading Kibana dashboards using Metricbeat through HELM charts

Deploying Jenkins on Google Cloud
3 projects | dev.to | 28 Jul 2021
In this step opta generates terraform code to deploys helm chart. You can review the plan and accept it. It will take around 2-3 minutes for the plan to get applied. For specifying values to the helm chart you can modify the values inside opta-gcp/opta.yml . Refer to jenkins helm chart for more details https://github.com/helm/charts/tree/master/stable/jenkins. After opta apply finishes you will have jenkins up and running on your infra.
k8s-secretgen: Got tired of generating secrets for testing stuff so I made a script to automate it.

I do use Helm to deploy, but the trouble with using it for secrets is that it overwrites them on an upgrade.

Next, we will also need to deploy services that collect metrics based on which we will later scale our test application. First of these is Kubernetes metrics-server which is usually available in cluster by default, but that's not the case in KinD, so to deploy it we need to run:
Kubernetes Horizontal Pod Autoscaling
3 projects | dev.to | 16 Jun 2022
Horizontal Pod Autoscaler (and also Vertical Pod Autoscaler) requires a Metrics Server installed in the Kubernetes cluster. Metric Server is a container resource metrics (such as memory and CPU usage) source that is scalable, can be configured for high availability, and is efficient on resource usage when operating. Metrics Server gather metrics -by default- every 15 seconds from Kubelets, this allows rapid autoscaling,
