Create a container

[mterhar]

Files are in comments below.

Steps

This uses docker rather than installing any depdenceies locally.

docker build --tag otelcol-libhoney:local .

This runs a 2 stage build with go:1.23 and then creates a container that runs otelcol-custom.

To use the container, put a n otel config file in a directory and run

docker run --rm \
  -v ./otel_config_libhoney.yaml:/config.yaml \
  -p 8088:8088 \
  -e HOSTNAME="$(hostname)" \
  otelcol-libhoney:local

Make sure you add the -p for any ports you're exposing for OTLP or other receivers as well.
