There are instructions on how to build the RPM.

Grab gofed from https://github.com/gofed/gofed

Choose which version of the repo you want to build. For kompose it was 0.3.0 and the commit was 135165b39c55d29a5426479ded81eddd56bfbaf4

Run the following to generate spec file:

gofed repo2spec --detect github.com/kubernetes/kompose --commit 135165b39c55d29a5426479ded81eddd56bfbaf4 --with-extra --with-build -f

The spec file is now located at:

$HOME/gofed/golang-github-kubernetes-incubator-kompose/golang-github-kubernetes-incubator-kompose.spec

Now we need to go through and fix some things.

Generate bundled dependencies by using parsedeps.go

Go to the kompose source folder and then run:

go run parsedeps.go

In the future this will possibly done by gofed, see: gofed/gofed#42

First, follow instructions to do local setup https://wiki.centos.org/HowTos/SetupRpmBuildEnvironment

Source: https://wiki.centos.org/HowTos/RebuildSRPM

Second, checkout the source to the release commit

Copy the kompose code directory with name kompose-135165b39c55d29a5426479ded81eddd56bfbaf4

Tar the kompose-135165b39c55d29a5426479ded81eddd56bfbaf4 code directory as kompose-135165b.tar.gz and copy it to $HOME/rpmbuild/SOURCES/

Run following command:

rpmbuild -ba kompose.spec

Find the srpm in $HOME/rpmbuild/SRPMS

Find the RPM in $HOME/rpmbuild/RPM/arch/

Check that the dependencies are proper:

rpm -qpR RPMS/x86_64/kompose-0.3.0-0.1.git135165b.el7.centos.x86_64.rpm

First, setup your environment in order to run Koji: https://fedoraproject.org/wiki/Using_the_Koji_build_system

Example setup:

fedora-packager-setup
kinit <username>@FEDORAPROJECT.ORG

To build it on koji run:

koji build --scratch rawhide kompose-0.3.0-0.1.git135165b.el7.centos.src.rpm
