Dockerfile

# Deploy php-quickjs on AWS Lambda as a container image (Bref's recommended path
# for custom binaries). Build for the architecture you deploy to: linux/arm64
# (Graviton) or linux/amd64.
#
#   docker build --platform linux/arm64 \
#     --build-arg EXT=php-quickjs-v0.0.2-php8.4-lambda-bref-arm64.so -t my-app .
#
# The base image MUST match the target arch: Bref ships separate runtimes per
# arch — `bref/arm-php-84` for arm64 (Graviton) and `bref/php-84` for x86_64.
# Override BREF_IMAGE to switch (the default below tracks serverless.yml's arm64):
#
#   docker build --platform linux/amd64 \
#     --build-arg BREF_IMAGE=bref/php-84:3 \
#     --build-arg EXT=php-quickjs-v0.0.2-php8.4-lambda-bref-x86_64.so -t my-app .
#
# Always pin the Bref image MAJOR version. Match the PHP minor (8.4/8.5), the
# base image arch, and the .so arch to each other.

# /opt/bref/extensions is Bref's extension_dir, and /opt/bref/etc/php/conf.d is
