Cloud-Native Microservices With Kubernetes - 2nd Edition

Installing Prometheus

This section focuses on installing Prometheus in our cluster. It can be installed on an external machine or cluster, but for simplicity, we use the same cluster where our microservices are running. Each approach has its pros and cons, and the choice depends on your specific use case.

In the next parts, we will use the Prometheus Operator.

ℹ️ Operators are defined as software extensions to Kubernetes that use custom resources to manage applications, their components, and most importantly, their entire lifecycle.

Create a working directory and navigate into it:

cd $HOME && mkdir -p monitoring && cd monitoring

Clone the Prometheus Operator repository:

# Clone the Prometheus Operator repository
git clone \
  https://github.com/prometheus-operator/kube-prometheus.git

# Navigate into the kube-prometheus directory
cd kube-prometheus

# Git checkout a stable release
git checkout release-0.16
