Add Helm repositories:
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add cortex-helm https://cortexproject.github.io/cortex-helm-chart
helm repo update
Install Cortex:
Create a values file (let's name it cortex-values.yaml) with the Cortex configuration you provided earlier. Here's an example of how it might look:
vi cortex-values.yaml
metaMonitoring:
serviceMonitor:
enabled: true
labels:
release: kube-prometheus-stack
config:
blocks_storage:
backend: s3
s3:
bucket_name: cortex-prod-north-virginia
endpoint: s3.us-east-1.amazonaws.com
region: us-east-1
access_key_id: "your-access-key-id"
secret_access_key: "your-secret-access-key"
tsdb:
dir: /data/tsdb
bucket_store:
sync_dir: /data/tsdb

enabled: true

Replace "your-access-key-id" and "your-secret-access-key" with your actual AWS access key ID and secret access key.
install Cortex using Helm:
helm upgrade cortex cortex-helm/cortex -f cortex-values.yaml --namespace cortex --create-namespace --install
Install kube-prometheus-stack: Create a values file (let's name it kube-prometheus-stack-values.yaml) for kube-prometheus-stack:
vi kube-prometheus-stack-values.yaml
prometheus:
prometheusSpec:
remoteWrite:
- url: http://cortex.cortex:80/api/v1/push
externalLabels:
environment: cortex-prod
install kube-prometheus-stack using Helm:
helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack -f kube-prometheus-stack-values.yaml --namespace monitoring --create-namespace
This setup will deploy Cortex with S3 storage backend and kube-prometheus-stack configured to send metrics to Cortex. Adjust configurations as per your specific environment and requirements.
