# Dockerfile for running otel-js tests in isolation from pnpm workspace
# Build context: SDK repository root
# Usage:
#   docker build -f integrations/otel-js/Dockerfile.test --build-arg NODE_VERSION=22 --build-arg TEST_DIR=otel-v1 -t otel-js-test-v1 .
#   docker run --rm otel-js-test-v1

# NODE_VERSION must be provided via --build-arg (e.g., --build-arg NODE_VERSION=20)
# Using placeholder default to avoid Docker warning - build will fail if not overridden
ARG NODE_VERSION=REQUIRED
ARG TEST_DIR
FROM node:${NODE_VERSION}-bookworm-slim

# Redeclare ARGs after FROM (ARGs are scoped to build stage)
ARG NODE_VERSION
ARG TEST_DIR

# Validate that required build arguments are provided
