With Pushgateway

Ensure your docker-compose.yml is configured correctly, and your Prometheus configuration files (prometheus1.yml and prometheus2.yml) are set to scrape the Pushgateway.

Update your Prometheus configuration files to include the Pushgateway as a scrape target:

yaml
Copy code
global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'pushgateway'
    static_configs:
      - targets: ['pushgateway:9091']
Pushing Metrics to Pushgateway
Use the following curl command to push metrics to the Pushgateway in the correct format:

sh
Copy code
curl -X POST http://localhost:9093/metrics/job/myjob/instance/myinstance --data-binary @- <<EOF
sample_metric 123.45
EOF
Querying Data from Prometheus
Query the data from Prometheus as follows:

Query the current value of sample_metric:
sh
Copy code
# Query the current value of sample_metric from prometheus1
curl 'http://localhost:9090/api/v1/query?query=sample_metric'

# Query the current value of sample_metric from prometheus2
curl 'http://localhost:9092/api/v1/query?query=sample_metric'
Query data over a time range:
sh
Copy code
# Define end and start times
end_time=$(date +%s)
start_time=$(($end_time - 3600))

# Query the sample_metric over the last hour from prometheus1
curl 'http://localhost:9090/api/v1/query_range' --data-urlencode "query=sample_metric" --data-urlencode "start=$start_time" --data-urlencode "end=$end_time" --data-urlencode "step=15s"

# Query the sample_metric over the last hour from prometheus2
curl 'http://localhost:9092/api/v1/query_range' --data-urlencode "query=sample_metric" --data-urlencode "start=$start_time" --data-urlencode "end=$end_time" --data-urlencode "step=15s"
This setup ensures that there are no port conflicts, metrics are pushed to the Pushgateway in the correct format, and you can query these metrics from Prometheus.

Old no pushgateway

Running multiple Prometheus servers with Thanos and MinIO for object storage. This setup assumes you want to run two Prometheus instances, one MinIO instance for storage, and the necessary Thanos components.

Here's an example of a docker-compose.yml configuration:

yaml
Copy code
version: '3.8'

services:
  minio:
    image: minio/minio
    container_name: minio
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: minio123
    command: server /data
    ports:
      - "9000:9000"
      - "9001:9001"
    volumes:
      - minio-data:/data

  prometheus1:
    image: prom/prometheus
    container_name: prometheus1
    volumes:
      - ./prometheus1.yml:/etc/prometheus/prometheus.yml
      - prometheus1-data:/prometheus
    ports:
      - "9090:9090"

  prometheus2:
    image: prom/prometheus
    container_name: prometheus2
    volumes:
      - ./prometheus2.yml:/etc/prometheus/prometheus.yml
      - prometheus2-data:/prometheus
    ports:
      - "9091:9090"

  thanos-store:
    image: thanosio/thanos:v0.24.0
    container_name: thanos-store
    command:
      - store
      - --objstore.config-file=/etc/thanos/minio.yml
      - --http-address=0.0.0.0:10902
    ports:
      - "10902:10902"
    volumes:
      - ./minio.yml:/etc/thanos/minio.yml

  thanos-sidecar-prometheus1:
    image: thanosio/thanos:v0.24.0
    container_name: thanos-sidecar-prometheus1
    command:
      - sidecar
      - --prometheus.url=http://prometheus1:9090
      - --tsdb.path=/prometheus
      - --objstore.config-file=/etc/thanos/minio.yml
    volumes:
      - prometheus1-data:/prometheus
      - ./minio.yml:/etc/thanos/minio.yml

  thanos-sidecar-prometheus2:
    image: thanosio/thanos:v0.24.0
    container_name: thanos-sidecar-prometheus2
    command:
      - sidecar
      - --prometheus.url=http://prometheus2:9090
      - --tsdb.path=/prometheus
      - --objstore.config-file=/etc/thanos/minio.yml
    volumes:
      - prometheus2-data:/prometheus
      - ./minio.yml:/etc/thanos/minio.yml

  thanos-querier:
    image: thanosio/thanos:v0.24.0
    container_name: thanos-querier
    command:
      - query
      - --http-address=0.0.0.0:10903
      - --store=thanos-store:10902
      - --store=thanos-sidecar-prometheus1:10901
      - --store=thanos-sidecar-prometheus2:10901
    ports:
      - "10903:10903"

volumes:
  minio-data:
  prometheus1-data:
  prometheus2-data:
You will also need a prometheus1.yml and prometheus2.yml configuration file for your Prometheus instances, as well as a minio.yml for the Thanos object storage configuration.

prometheus1.yml / prometheus2.yml
yaml
Copy code
global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']
minio.yml
yaml
Copy code
type: S3
config:
  bucket: "thanos"
  endpoint: "minio:9000"
  access_key: "minio"
  secret_key: "minio123"
  insecure: true
To get started, place the docker-compose.yml, prometheus1.yml, prometheus2.yml, and minio.yml files in the same directory, and then run:

bash
Copy code
docker-compose up -d
This will set up the environment with two Prometheus servers, MinIO for storage, Thanos Store, Thanos Sidecar for each Prometheus, and Thanos Querier for querying the data.
