Dockerfile

# This builds a Docker image including the Elastic Distribution of OpenTelemetry
# for Node.js (EDOT Node.js). This is typically published as:
#
#   docker.elastic.co/observability/elastic-otel-node:<TAG>
#
# The image is effectively the `@elastic/opentelemetry-node` npm package, with
# its dependencies, and a "autoinstrumentation.js" driver, as required by the
# OpenTelemetry Operator.
#
# To build this image, do the equivalent of the following. The build context is
# the *top* of the repo, because some build scripts outside of the package
# dir are required:
#   cd packages/opentelemetry-node
#   docker build -t <name>:<tag> -f ./Dockerfile ../../
#
# Typically the build is handled by CI, which also adds other build tags,
# handles provenance, etc.

# The OpenTelemetry Operator support for Node.js instrumentation requires:
# 1. all files under "/autoinstrumentation",
# 2. a working `cp` in the image for copying that directory to a shared volume,
# 3. a "autoinstrumentation.js" in that dir (will be used with `--require ...`).
