Can a UBI image variant be added?

[IdanAdar]

For compliance purposes, some cloud providers require images to be based on UBI by RedHat. To that end, we'd like Reloader to offer also an image based on UBI as base image next to distroless

@IdanAdar can you please add description and also reasoning?

Got it @IdanAdar PRs are welcome; we do lots of managed OpenShift as well; so, it will be a great addition

@rasheedamir Any guiding tips how this should be done for Reloader specifically?

We're building reloader from source internally with other build image as well as base image. To do that we use the BUILDER_IMAGE and BASE_IMAGE parameters to the Makefile. Perhaps you can use the same?

$ DOCKER_IMAGE=my.image.local/reloader \
   ARCH=amd64 \
   BASE_IMAGE=docker.io/redhat/ubi8-micro:latest \
   make build-image

Have a look at the Makefile.

If you don't want to build from source like we do, you can also use the binary from the published image in a new Dockerfile like this:

FROM docker.io/stakater/reloader:v1.0.15 as SRC

FROM docker.io/redhat/ubi8-micro:latest

WORKDIR /
COPY --from=SRC /manager .
USER 65532:65532

# Port for metrics and probes
EXPOSE 9090

ENTRYPOINT ["/manager"]

Build with docker build . -t my-reloader:v1.0.15

@IdanAdar did you manage to build the image and/or create a PR to publish UBI-based reloader?

[IdanAdar]

I could not, no.

[smuda]

What model did you try and what problem did you run into?

I also need this, for compliance reasons, so I have opened a PR. Happy to change whatever is needed to get it in.
