Requirements

Certificats

Create a folder named /home/docker/certs and copy your certificates into it.

sudo mkdir -p /home/docker/certs

Variables

Proxy (nginx)

Create the folder where the ngnix config will be stored and copy the config/nginx.conf into it

sudo mkdir -p /home/docker/nginx
sudo cp ./config/default.conf /home/docker/nginx/.

Minio

Create the folder where the minio data will be stored

sudo mkdir -p /home/docker/minio

Minio client

Create the folder where the minio client comfig will be stored

sudo mkdir -p /home/docker/minio-cli

Grafana

Create the folder where the grafana data will be stored

sudo mkdir -p /home/docker/grafana

Prometheus

Create the folder where the grafana data will be stored

sudo mkdir -p /home/docker/prometheus

Create the folder where the prometheus data will be stored

sudo mkdir -p /home/docker/prometheus-data

Run

docker compose up -d

Config

Minio client

Create an alias

docker exec -it <COMPOSE_PROJECT_NAME>-minio-cli-1 /bin/sh -c "mc alias set myminio http://minio:9000 <MINIO_ACCESS_KEY> <MINIO_SECRET_KEY>"

Create prometheus metrics job

docker exec -it <COMPOSE_PROJECT_NAME>-minio-cli-1 /bin/sh -c "mc admin prometheus generate myminio"

Copy the output into prometheus.yml

scrape_configs:
- job_name: minio-job
  bearer_token: eyJhbGciOiJIUzUxMiIs..InR5cCI6IkpXVCJ9
  metrics_path: /minio/v2/metrics/cluster
  scheme: http
  static_configs:
  - targets: ['minio:9000']

Restart prometheus

docker compose restart prometheus
