Deploying Prometheus with Docker
Prometheus can be easily deployed using Docker - official images are provided on Docker Hub.
Make sure you have Docker running on the system.
Create a file called
prometheus.yml with the following contents:
scrape_configs: - job_name: my-app-name metrics_path: /metrics static_configs: # Replace the port with the port your /metrics endpoint is running on - targets: ["localhost:3000"] scrape_interval: 15s
See the Prometheus configuration reference (opens in a new tab) for full details.
You can now run Prometheus with the configuration file you created:
docker run \ -p 9090:9090 \ -v prometheus.yml:/etc/prometheus/prometheus.yml \ prom/prometheus
If you're deploying Prometheus to production using Docker, it is a good practice to create a named persistent volume where Prometheus would store the data. This will ensure your metrics data persists even in case the container shuts down.
To create the volume run the
docker volume create <VOLUME_NAME> command:
docker volume create prometheus-data
And when starting up the Prometheus container make sure to tell Prometheus to use our
docker run \ -p 9090:9090 \ -v prometheus-data:/prometheus \ -v prometheus.yml:/etc/prometheus/prometheus.yml \ prom/prometheus
Your Prometheus should now be accessible on
