openSUSE Tumbleweed BCI Nano: Suitable for deploying static binaries

Description

The bci-nano image is providing timezone and TLS trusted CA certificates, but no shell or glibc. This means that the image is smaller than bci-micro. The primary use case for the image is deploying static binaries produced externally or during multi-stage builds which do not require any shell environment.

Usage

As there is no straightforward way to install additional dependencies inside the container image, we recommend deploying a project using the bci-nano image only when the final build artifact bundles all dependencies and needs no further installation of packages.

Example using a Go application:

FROM registry.opensuse.org/opensuse/bci/golang:stable as build

WORKDIR /app

RUN go install github.com/go-training/helloworld@latest

# Create an image to bundle the app
FROM registry.opensuse.org/opensuse/bci/bci-nano:latest

COPY --from=build /go/bin/helloworld /usr/local/bin/helloworld

CMD ["/usr/local/bin/helloworld"]
