OpenTelemetry PHP Autoinstrumentation

Builds the OpenTelemetry PHP autoinstrumentation image published to GitHub Container Registry.

What it builds

• PHP 8.1, 8.2, 8.3, 8.4, and 8.5
• glibc and musl variants
• ZTS and non-ZTS variants

Build locally

The final target is configured as a multi-platform build (see docker-bake.hcl), so depending on your Buildx driver you may need to select a single platform and/or set an output (e.g., --load) to get a runnable local image.

docker buildx bake

Build and push:

docker buildx bake --push

Build extension artifacts for a single variant (intermediate build target; does not build/tag the final image):

docker buildx bake build-non-zts-81

Override the release version and tag:

OPENTELEMETRY_VERSION=1.4.0 TAG=1.4.0 docker buildx bake 

Release flow

Create and push a version tag:

git tag 1.0.0
git push origin 1.0.0

GitHub Actions builds the image and pushes it to GHCR.
