Bldr (Pronounced Boulder) performs RPM builds using a templated RPM specfile.
Given a specfile and value file, bldr will facilitate rendering the specfile and performing an RPM build. This utility is distributed as a container image
jharshman/bldr.
While not required, it is reccomended to composing your own Dockerfile based on jharshman/bldr:latest. This Dockerfile will serve as the sterile environment in which you build your RPM. Here you can install whatever software is required for your build. In the past this was done by way of Chroot Jails, but I find it more user friendly to use Docker for this instead.
Here is the Dockerfile used for building the small Go project in the examples directory.
FROM --platform=arm64 jharshman/bldr:latest
RUN zypper in -y wget
RUN wget https://go.dev/dl/go1.22.1.linux-amd64.tar.gz && tar -C /usr/local -xzf go1.22.1.linux-amd64.tar.gz
RUN export PATH=$PATH:/usr/local/go/binYou don't have to clone this repo or install a binary to start using bldr. The bldr.sh script will run the utility and can be used as follows.
