Quickstart for Docker on Elastic Cloud Hosted

Elastic Stack Serverless Observability

Learn how to set up the EDOT Collector and EDOT SDKs in a Docker environment with Elastic Cloud Hosted (ECH) to collect host metrics, logs, and application traces.

Make sure the following requirements are present:

  • Docker installed and running.
  • The System integration is installed in Kibana. Select Add integration only to skip the agent installation, as only the integration assets are required.

Use the Add data screen in Elastic Observability to generate install commands that are already configured with the values you need.

  1. Open Elastic Observability.
  2. Go to Add data.
  3. Select what you want to monitor.
  4. Follow the instructions.

Follow these steps to deploy the EDOT Collector and EDOT OTel SDKs in Docker with ECH.

  1. Create the config file

    Create the otel-collector-config.yml file with your EDOT Collector configuration. Refer to the configuration reference.

  2. Retrieve your settings

    Retrieve your Elasticsearch URL and your API key:

    1. Retrieve the Elasticsearch URL for your Elastic Cloud deployment:

      1. Go to the Elastic Cloud console.
      2. Next to your deployment, select Manage.
      3. Under Applications next to Elasticsearch, select Copy endpoint.

    2. Create an API Key following these instructions.

  3. the .env file

    Create an .env file with the following content. Replace the placeholder values with your Elastic Cloud credentials:

    HOST_FILESYSTEM=/
DOCKER_SOCK=/var/run/docker.sock
ELASTIC_AGENT_OTEL=true
COLLECTOR_CONTRIB_IMAGE=elastic/elastic-agent:9.0.0
ELASTIC_API_KEY=<your_api_key_here>
ELASTIC_ENDPOINT=<your_endpoint_here>
OTEL_COLLECTOR_CONFIG=/path/to/otel-collector-config.yml

  4. Create the compose file

    Create a compose.yml file with the following content:

    services:
 otel-collector:
   image: ${COLLECTOR_CONTRIB_IMAGE}
   container_name: otel-collector
   deploy:
     resources:
       limits:
         memory: 1.5G
   restart: unless-stopped
   command: ["--config", "/etc/otelcol-config.yml" ]
   network_mode: host
   user: 0:0
   volumes:
     - ${HOST_FILESYSTEM}:/hostfs:ro
     - ${DOCKER_SOCK}:/var/run/docker.sock:ro
     - ${OTEL_COLLECTOR_CONFIG}:/etc/otelcol-config.yml
   environment:
     - HOST_FILESYSTEM
     - ELASTIC_API_KEY
     - ELASTIC_ENDPOINT
     - ELASTIC_AGENT_OTEL
     - STORAGE_DIR=/usr/share/elastic-agent

  5. Start the Collector

    Start the Collector by running:

    docker compose up -d

  6. (Optional) Instrument your applications

    To collect telemetry from applications running on the host where you installed the EDOT Collector, instrument your target applications following the setup instructions for the corresponding language:

    Configure your SDKs to send the data to the local EDOT Collector using OTLP/gRPC (http://localhost:4317) or OTLP/HTTP (http://localhost:4318).
