Stackable Docker Images
This repository contains Dockerfiles and scripts to build base images for use within Stackable.
ubi8-rust-builder
This image is meant to be used in multi-stage builds as a base image for projects building Rust projects.
The image will run cargo build --release in the current context and copy all binaries to an /app directory.
This will bake in the current stable Rust version at the time this image was built which means it should be rebuilt (and tagged) for every release of Rust.

ENTRYPOINT ["/stackable-zookeeper-operator"]Build Product Images
Product images are published to the docker.stackable.tech registry under the stackable organization.
This uses the Docker CLI plugin buildx which is not necessarily installed by default when installing Docker.
Make sure that docker buildx works before running the following commands.
To build and push product images to the default repository, use the build_product_images.py like this:
python -m image_tools.bake --product zookeeper --image 0.0.0-dev --push
This will build images for Apache ZooKeeper versions as defined in the image_tools/conf.py and tag them with the image-version 0.0.0-dev
The GitHub action called Product images can be triggered manually to do the same but not on the local machine.
Verify Product Images
To verify if Apache Zookeeper validate against OpenShift preflight, run:
python -m image_tools.preflight --product zookeeper --image 0.0.0-dev
