Deploying Mimir Scalable Metrics Storage on Ubuntu 24.04

Mimir is an open-source, horizontally scalable long-term storage backend for Prometheus metrics from Grafana Labs. It accepts metrics via Prometheus remote write and serves them back through a Prometheus-compatible query API. This guide deploys Mimir using Docker Compose with Traefik handling automatic HTTPS, and verifies the backend through its status endpoints, following scalable metrics storage practices documented in Vultr Docs.

Set Up the Directory Structure

1. Create the project directory structure:

$ mkdir -p ~/mimir-metrics/{mimir-data,mimir-config}
$ cd ~/mimir-metrics

2. Create the environment file:

$ nano .env

DOMAIN=mimir.example.com
LETSENCRYPT_EMAIL=admin@example.com

3. Create the Mimir configuration file:

$ nano mimir-config/mimir-config.yaml

multitenancy_enabled: false

server:
  http_listen_port: 9009
  log_level: info

blocks_storage:
  backend: filesystem
  filesystem:
    dir: /data/blocks
  tsdb:
    dir: /data/tsdb
    retention_period: 24h

compactor:
  data_dir: /data/compactor
  sharding_ring:
    kvstore:
      store: memberlist

distributor:
  ring:
    kvstore:
      store: memberlist

ingester:
  ring:
    kvstore:
      store: memberlist
    replication_factor: 1

store_gateway:
  sharding_ring:
    kvstore:
      store: memberlist

ruler_storage:
  backend: filesystem
  filesystem:
    dir: /data/rules

limits:
  max_global_series_per_user: 0
  ingestion_rate: 0
  ingestion_burst_size: 0

Deploy with Docker Compose

1. Create the Docker Compose manifest:

$ nano docker-compose.yaml

services:
  traefik:
    image: traefik:v3.6
    container_name: traefik
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--entrypoints.web.http.redirections.entrypoint.to=websecure"
      - "--entrypoints.web.http.redirections.entrypoint.scheme=https"
      - "--certificatesresolvers.letsencrypt.acme.httpchallenge=true"
      - "--certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=web"
      - "--certificatesresolvers.letsencrypt.acme.email=${LETSENCRYPT_EMAIL}"
      - "--certificatesresolvers.letsencrypt.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    restart: unless-stopped

  mimir:
    image: grafana/mimir:latest
    container_name: mimir
    hostname: mimir
    expose:
      - "9009"
    volumes:
      - "./mimir-config/mimir-config.yaml:/etc/mimir/mimir-config.yaml"
      - "./mimir-data:/data"
    command: -config.file=/etc/mimir/mimir-config.yaml
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.mimir.rule=Host(`${DOMAIN}`)"
      - "traefik.http.routers.mimir.entrypoints=websecure"
      - "traefik.http.routers.mimir.tls.certresolver=letsencrypt"
      - "traefik.http.services.mimir.loadbalancer.server.port=9009"
    restart: unless-stopped

volumes:
  letsencrypt:

2. Start the services:

$ docker compose up -d

3. Verify the services are running:

$ docker compose ps

4. View the logs:

$ docker compose logs

Access Mimir

1. Check the readiness endpoint:

$ curl https://mimir.example.com/ready

A ready response confirms the backend is up.

2. Check the build information:

$ curl https://mimir.example.com/api/v1/status/buildinfo

3. Query the running configuration:

$ curl https://mimir.example.com/api/v1/status/config

4. Check the ingester ring:

$ curl https://mimir.example.com/ingester/ring

Next Steps

Mimir is running and ready to accept Prometheus metrics over HTTPS. From here you can:

• Configure Prometheus remote_write to push metrics to your Mimir domain

• Add Mimir as a Prometheus data source in Grafana for long-term queries

• Move block storage to S3-compatible object storage for durable retention
