cAdvisor docker service doesn't publish name o image tag to use in Prometheus

Question

I'm an absolute beginner in the monitoring world but I've deployed some services using docker-compose:

• cAdvisor
• Prometheus
• Grafana

My hope was to be able to show metrics on Grafana querying Prometheus and show the containers up or the state of service scraping the metrics of cAdvisor but in many examples I've followed they showed how you can query for example:

• container_last_seen{image="blah"}
• container_last_seen{name="blah"}

But I'm not able because cAdvisor is not publishing metrics with these labels.

My docker-compose.yml is like:

version: "3.9"

services:
  backend:
    [... hide this code for privacy]
  frontend:
    [... hide this code for privacy]
  db:
    image: arm64v8/mysql:8.0
    [... hide this code for privacy]

  prometheus:
    image: prom/prometheus:v2.46.0
    container_name: prometheus
    volumes:
      - ./prometheus:/etc/prometheus
      - prometheus_data:/prometheus
    command:
      - "--config.file=/etc/prometheus/prometheus.yml"
      - "--storage.tsdb.path=/prometheus"
      - "--web.console.libraries=/etc/prometheus/console_libraries"
      - "--web.console.templates=/etc/prometheus/consoles"
      - "--storage.tsdb.retention.time=200h"
      - "--web.enable-lifecycle"
      - "--web.enable-remote-write-receiver"
      - "--enable-feature=native-histograms"
    restart: unless-stopped
    expose:
      - 9090
    networks:
      - monitor-net
    labels:
      org.label-schema.group: "monitoring"
    user: root

  cadvisor:
    image: gcr.io/cadvisor/cadvisor:v0.47.1
    container_name: cadvisor
    privileged: true
    devices:
      - /dev/kmsg:/dev/kmsg
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:ro
      - /sys:/sys:ro
      - /var/lib/docker:/var/lib/docker:ro
      #- /cgroup:/cgroup:ro #doesn't work on MacOS only for Linux
    restart: unless-stopped
    expose:
      - 8080
    networks:
      - monitor-net
    labels:
      org.label-schema.group: "monitoring"

  grafana:
    image: grafana/grafana-enterprise
    container_name: grafana
    ports:
      - "3100:3000"
    volumes:
      - grafana_data:/var/lib/grafana
    environment:
      - GF_SECURITY_ADMIN_USER=${ADMIN_USER:-admin}
      - GF_SECURITY_ADMIN_PASSWORD=${ADMIN_PASSWORD:-admin}
      - GF_USERS_ALLOW_SIGN_UP=false
    restart: unless-stopped
    expose:
      - 3100
    networks:
      - monitor-net

networks:
  monitor-net:
    driver: bridge

volumes:
  dev-db-data:
  dev-static-data:
  grafana_data: {}
  prometheus_data: {}

And my prometheus.yml:

global:
  scrape_interval:     15s
  evaluation_interval: 15s

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
      monitor: 'docker-host-alpha'

# A scrape configuration containing exactly one endpoint to scrape.
scrape_configs:
  - job_name: 'nodeexporter'
    scrape_interval: 5s
    static_configs:
      - targets: ['nodeexporter:9100']

  - job_name: 'cadvisor'
    scrape_interval: 5s
    static_configs:
      - targets: ['cadvisor:8080']

  - job_name: 'prometheus'
    scrape_interval: 10s
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'pushgateway'
    scrape_interval: 10s
    honor_labels: true
    static_configs:
      - targets: ['pushgateway:9091']

I tried: docker-compose up checked all my services were up and running check the cAdvisor /metrics

But no tags name or image were found.

Any help, any clue would be much appreciate.
