Access to docker.sock in addon

Installation Home Assistant OS
1

Hi All,

I tried to search everywhere for this, but missing to find any info around how to expose the docker socker and other items to my custom Datadog v5 agent. I really like the datadog agent monitoring around docker and system performance and figured to write a plugin that exposes this info, perhaps including pulling of the logs to datadog.

My issue seems to be, knowing what to use on both a privilege side and a config.json side. I see in the addons repo there is a specific component for providing privileges to another addon, but cant see this in the hassio vagrant image to install it. as well as docs on what to configure.

I have tried to put the configs under maps and under devices (which fails).

Would really appreciate any help. Config below.

config.json

I’ve got the datadog agent starting up nicely now in the container, just need help with figuring out how you allow a addon to use the docker socket. Effectively binding these 3 “volumes”

     "/var/run/docker.sock:/var/run/docker.sock:ro",
     "/proc/:/host/proc/:ro",
     "/sys/fs/cgroup/:/host/sys/fs/cgroup:ro"

when i run the addon manually on my machine, i feed this command in.

docker run -d \                   
  -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 API_KEY=xxxx \
  hassio-addon/datadog-v5:0.0.11

Has anyone found a way to make systemd work in a home assistant addon?
