Dockerfile to put the newrelic-infra agent into a container

newrelic-infra

WIP!

This is my attempt at hosting the newrelic-infra agent inside a Docker container. Mostly inspired from this post, and this example in the Kubernetes source. The example in the K8s source doesn't work for newer NewRelic accounts, where servers have been removed in favour of the new infrastructure pages.

Building

A simple docker build should be sufficient from within the root of the repo.

Running

Manually using Docker

The below example assumes you've set the NRIA_LICENSE_KEY environment variable to your license key before you run docker run.

docker run \
       --rm \
       --uts=host \
       --pid=host \
       --net=host \
       --privileged=true \
       -e NRIA_LICENSE_KEY="$NRIA_LICENSE_KEY" \
       -v /:/mnt/ROOT:ro \
       rk295/newrelic-infra

Running from inside Kubernetes
