how to build a custom datadog-agent image
Dockerfile
The docker file takes as base image the lastest datadog/agent image.
To use the latest you can run docker pull datadog/agent:7 before running the docker build command.
FROM datadog/agent:7
# install a custom conf
COPY ./conf.d/hello.d/conf.yaml conf.d/hello.d/
# install a custom check
COPY ./checks.d/hello.py checks.d/hello.py
if you want to build an image with the JMX support, the base image is: datadog/agent:7-jmx
build the image
docker build -t mycustom/agent .run the agent
docker run -d --name dd-agent -v /var/run/docker.sock:/var/run/docker.sock:ro -v /proc/:/host/proc/:ro -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro -e DD_API_KEY=$DD_API_KEY mycustom/agent
