Containerized Agent

The infrastructure agent support Docker version 1.12 or higher.

Precondition

Be sure you already built the agent binaries, so these should be available at project root target/ folder.

make build/base builds the Docker image from this repo's Dockerfile.

The make target generates the Docker image in steps:

Adds the newrelic-infra agent binary.
Generates and adds a VERSION file.
Adds all files in static assets.
Sets image labels.
Sets image environment variables required for the agent to run correctly inside a container.

See the comments in Makefile for the required env vars.

To build the Linux binary, see the README instructions. That will produce the newrelic-infra binary in target/bin/.

Set the following environment variables:
- PROJECT_ROOT: Path to this cloned repo's root
- IMAGE_VERSION: Version to use for the Docker image
- IMAGE_TAG: newrelic/infrastructure
- AGENT_VERSION: Version of the newrelic-infra agent
Create a workspace directory in the repo root:
```
mkdir ${PROJECT_ROOT}/workspace
```
Copy or move your newrelic-infra binary into ${PROJECT_ROOT}/workspace/. The binary must be named newrelic-infra.
Run the make target: make build/base

This should build the Docker image newrelic/infrastructure and tag it with latest.
