Alpine image with kinesis_producer compiled for Alpine Linux / musl

This directory includes the Docker scripts to build an image with kinesis_producer for Alpine Linux. kinesis_producer is a native executable that is required by Amazon Kinesis Producer library (KPL) which is used by the Pulsar IO Kinesis Sink connector. The default kinesis_producer binary is compiled for glibc, and it does not work on Alpine Linux which uses musl.

This image only needs to be re-created when we want to upgrade to a newer version of kinesis_producer.

Steps

  1. Change the version in the Dockerfile for this directory.
  2. Rebuild the image and push it to Docker Hub:
IMAGE=apachepulsar/pulsar-io-kinesis-sink-kinesis_producer
KINESIS_PRODUCER_VERSION=1.0.4
docker buildx build --platform=linux/amd64,linux/arm64 \
 -t "$IMAGE:$KINESIS_PRODUCER_VERSION" -t "$IMAGE:${KINESIS_PRODUCER_VERSION}-$(date -I)" \
 . --push

The image tag is then used in docker/pulsar-all/Dockerfile. The kinesis_producer binary is copied from the image to the pulsar-all image that is used by Pulsar Functions to run the Pulsar IO Kinesis Sink connector. The environment variable PULSAR_IO_KINESIS_KPL_PATH is set to /opt/amazon-kinesis-producer/bin/kinesis_producer and this is how the Kinesis Sink connector knows where to find the kinesis_producer binary.
