Challenge, Easy,  on  Kubernetes

Expose Observability Stack (Prometheus and Grafana) Using Traefik

Scenario

Helm has already installed Prometheus and Grafana in the namespace platform-observability.

DNS entries for iximiuz.prometheus.io and iximiuz.grafana.io are already configured in /etc/hosts.

Create an Ingress resource named observability-ingress in the namespace platform-observability.

  • Configure the Ingress to route all HTTP traffic for iximiuz.prometheus.io to the Service prometheus-kube-prometheus-prometheus on port 9090.
  • Configure the Ingress to route all HTTP traffic for iximiuz.grafana.io to the Service prometheus-grafana on port 80.
  • Both Ingress rules with path / with pathType: Prefix.
  • Set the Ingress class to traefik.

Do not modify any existing Services.

The Grafana credentials for UI access are located at /home/laborant/grafana-credentials.

# Test Prometheus access
curl -v http://iximiuz.prometheus.io/query

# Test Grafana access
curl -v http://iximiuz.grafana.io/login
Hint

You need to create a single Ingress with two rules, one for each hostname. Each rule should have a path / with pathType: Prefix pointing to its respective service and port.

How to Author Challenges on iximiuz Labs

Instead of providing a subpar online editing experience, iximiuz Labs offers a helper CLI tool called labctl, allowing you to use your favorite text editor (or a full-featured IDE) to write content from the comfort of your local machine.

Install labctl CLI

curl -sf https://labs.iximiuz.com/cli/install.sh | sh

This will download and install the latest version of the labctl CLI. You only need to do this once per workstation.

Authorize labctl

labctl auth login

This will open a browser window asking you to authorize labctl to access your account. You need to do it after a fresh install of labctl and repeat it whenever the auth session expires.

Pull challenge content

labctl content pull challenge expose-prometheus-and-grafana-using-traefik-ingress-479b065f

This will create a local copy of the challenge content in a directory named expose-prometheus-and-grafana-using-traefik-ingress-479b065f. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge expose-prometheus-and-grafana-using-traefik-ingress-479b065f

Run this command in a separate terminal to continuously upload your changes to the server while editing the challenge in your favorite text editor or IDE.

You can also use labctl to create, list, and delete your content. Learn more about the available commands: labctl content --help
