Or, if you want a dockerized version of DataDog agent, and you want to listen to docker logs, you can do this:

docker run -d --name datadog-agent \
           -e DD_API_KEY=<DATADOG_API_KEY> \
           -e DD_LOGS_ENABLED=true \
           -e DD_LOGS_CONFIG_CONTAINER_COLLECT_ALL=true \
           -e DD_CONTAINER_EXCLUDE_LOGS="name:datadog-agent" \
           -e DD_SITE="datadoghq.eu"  \
           -v /var/run/docker.sock:/var/run/docker.sock:ro \
           -v /proc/:/host/proc/:ro \
           -v /opt/datadog-agent/run:/opt/datadog-agent/run:rw \
           -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \
           datadog/agent:latest

docker run -d --name datadog-agent \

-e DD_API_KEY=<DATADOG_API_KEY> \

-e DD_LOGS_ENABLED=true \

-e DD_LOGS_CONFIG_CONTAINER_COLLECT_ALL=true \

-e DD_CONTAINER_EXCLUDE_LOGS="name:datadog-agent" \

-e DD_SITE="datadoghq.eu" \

-v /var/run/docker.sock:/var/run/docker.sock:ro \

-v /proc/:/host/proc/:ro \

-v /opt/datadog-agent/run:/opt/datadog-agent/run:rw \

-v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \

datadog/agent:latest
