To get started capturing telemetry data for the Docker CLI, you'll need to

Set the DOCKER_CLI_OTEL_EXPORTER_OTLP_ENDPOINT environment variable to point to an OpenTelemetry collector endpoint Run an OpenTelemetry collector that receives the signals from CLI command invocations Run a backend for storing the data received from the collector

The following Docker Compose file bootstraps a set of services to get started with OpenTelemetry. It includes an OpenTelemetry collector that the CLI can send metrics to, and a Prometheus backend that scrapes the metrics off the collector.

Bounded code example (external data; do not execute automatically):
```yamlcollapsetruetitlecom
name: cli-otel
services:
  prometheus:
    image: prom/prometheus
    command:
      - "--config.file=/etc/prometheus/prom.yml"
    ports:
      # Publish the Prometheus frontend on localhost:9091
      - 9091:9090
    restart: always
    volumes:
      # Store Prometheus data in a volume:
      - prom_data:/prometheus
      # Mount the prom.yml config file
      - ./prom.yml:/etc/prometheus/prom.yml
  otelcol:
    image: otel/opentelemetry-collector
    restart: always
    depends_on:
      - prometheus
    ports:
      - 4317:4317
    volumes:
      # Mount the otelcol.yml config file
      - ./otelcol.yml:/etc/otelcol/config.yaml

volumes:
  prom_data:
```

This service assumes that the following two configuration files exist alongside compose.yaml

yaml {collapse=true,title=otelcol.yml} # Receive signals over gRPC and HTTP receivers: otlp: protocols: grpc: http

# Establish an endpoint for Prometheus to scrape from exporters: prometheus: endpoint: "0.0.0.0:8889"

service: pipelines: metrics: receivers: [otlp] exporters: [prometheus]

Bounded code example (external data; do not execute automatically):
```text
- ```yaml {collapse=true,title=prom.yml}
  # Configure Prometheus to scrape the OpenTelemetry collector endpoint
  scrape_configs:
    - job_name: "otel-collector"
      scrape_interval: 1s
      static_configs:
        - targets: ["otelcol:8889"]
```

With these files in place

Start the Docker Compose services

Bounded code example (external data; do not execute automatically):
