+# Docker Integration
+
+This Integration fetches metrics from [Docker](https://www.docker.com/) containers. The default data streams are: `container`, `cpu`, `diskio`, `healthcheck`, `info`, `memory` and `network`. The `image` metricset is not enabled by default.
+
+## Compatibility
+
+The Docker module is currently tested on Linux and Mac with the community
+edition engine, versions 1.11 and 17.09.0-ce. It is not tested on Windows,
+but it should also work there.
+
+## Running from within Docker
+
+The `docker` Integration will try to connect to the docker socket, by default at `unix:///var/run/docker.sock`. 
+If Elastic Agent is running inside docker, you'll need to mount the unix socket inside the container:
+
+```
+docker run -d \
+  --name=metricbeat \
+  --user=root \
+  --volume="/var/run/docker.sock:/var/run/docker.sock:ro" \
+  docker.elastic.co/beats/metricbeat:latest metricbeat -e \
+  -E output.elasticsearch.hosts=["elasticsearch:9200"]
+```
+
+## Module-specific configuration notes
+
+It is strongly recommended that you run Docker metricsets with a
+<<metricset-period,`period`>> that is 3 seconds or longer. The request to the
+Docker API already takes up to 2 seconds. Specifying less than 3 seconds will
+result in requests that timeout, and no data will be reported for those
+requests.
+
+## Metrics
+
+### Container
+
+The Docker `container` data stream collects information and statistics about
+running Docker containers.
+
+{{fields "container"}}
+
+{{event "container"}}
+
+### CPU 
+
+The Docker `cpu` data stream collects runtime CPU metrics.
+
+{{fields "cpu"}}
+
+{{event "cpu"}}
+
+### Diskio
+
+The Docker `diskio` data stream collects disk I/O metrics.
+
+{{fields "diskio"}}
+
+{{event "diskio"}}
+
+### Event
+
+The Docker `event` data stream collects docker events
+
+{{fields "event"}}
+
+{{event "event"}}
+
+### Healthcheck
+
+The Docker `healthcheck` data stream collects healthcheck status metrics about
+running Docker containers.
+
+Healthcheck data will only be available from docker containers where the
+docker `HEALTHCHECK` instruction has been used to build the docker image.
+
+{{fields "healthcheck"}}
+
+{{event "healthcheck"}}
+
+### Image
+
+The Docker `image` data stream collects metrics on docker images
+
+{{fields "image"}}
+
+{{event "image"}}
+
+### Info 
+
+The Docker `info` data stream collects system-wide information based on the
+https://docs.docker.com/engine/reference/api/docker_remote_api_v1.24/#/display-system-wide-information[Docker Remote API].
+
+{{fields "info"}}
+
+{{event "info"}}
+
+### Memory
+
+The Docker `memory` data stream collects memory metrics from docker.
+
+{{fields "memory"}}
+
+{{event "memory"}}
+
+
+### Network
+
+The Docker `network` data stream collects network metrics.
+
+{{fields "network"}}
+
+{{event "network"}}
