Bug 1306214

The current srpm carries support for ppc64el. Although, have not tried to build k8s on the architecture.

Following kubernetes k8s upstream commits are needed:
4774e7146e0980b0ab9e0a8027e50254e7f6945d 
c969c041e2cda926e6d582175bea565353aed040

The only way I found to get it built is to point on 1.2.0-alpha.8 version
got from https://github.com/kubernetes/kubernetes/tree/v1.2.0-alpha.8

Patch keep-solid-port-for-kube-proxy.patch seems to not apply anymore.
This needs to be checked.

Also to have fedora ppc64le built, I needed to add two patches and to change the spec file. This needs to be reviewed.

- ppc64le-redhat-linux-gcc-path.patch
  This patch to change "powerpc64le-linux-gnu-gcc" reference by
  "ppc64le-redhat-linux-gnu"
This is specific to fedora and I guess a more elegant way exists to change this
and I am not sure if the problem is not in rpm macros.
rpm --eval "%{_target_platform}" returns "ppc64le-redhat-linux-gnu" 

in /usr/lib/rpm/macros
%host_vendor  redhat

dnf list rpm
Installed Packages
rpm.ppc64le                    4.13.0-0.rc1.25.fc24                     @rawhide


- golang-1.6-kube-path.patch
  This patch to change the go binary path of golang 1.6
Again, it seems to be specific to ppc64le as this path is not the same for x86-64 build on primary with the same golang... This needs to be investigated.

koji build --scratch f24 /root/test/kubernetes-1.2.0-gm_0.14.alpha8.f24.src.rpm
on primary:
http://koji.fedoraproject.org/koji/taskinfo?taskID=13308156
on secondary:
http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=3215054

Note that only ppc64le builds (no ppc64).
I just tried to build but did not do any functional tests.

golang path patch

ose/origin 1.1.4 release picks upstream's 91d3e753a4eca4e87462b7c9e5391ec94bb792d9 commit which already carries the patch.

Once kubernetes gets updated, supported architectures get extended to ppc64le as well.

I did a scratch build on ppc64le based on primary source and it failed.
see http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=3315227

I applied the 2 patches I previously attached on this bug and I changed the spec file to handle the 2 new patches and add the following change on kube path and
run a new koji scratch build.
koji scratch build of kubernetes patched built successfully.
see http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=3315264

kube path changed in spec:
# fix golang 1.6 kube path for fedora ppc64le
%if 0%{?fedora_on_ppc64le}
output_path="${KUBE_OUTPUT_BINPATH}"
%else
output_path="${KUBE_OUTPUT_BINPATH}/$(kube::golang::current_platform)"
%endif

Could it be possible to have these patches quickly in order to add kubernetes package in fedora 24 for secondary.
Thanks

Does the f24 build needs to be in updates or raw build in koji is enough?

We need all builds to go thru bodhi to be available on secondary arches.

In the patch attachment 1135226 [details] I proposed, I set gcc for ppc64le kubernetes.
It is a an error as we need to used "go" now.

The correct patch should have been:
diff --git a/hack/lib/golang.sh b/hack/lib/golang.sh
--- a/hack/lib/golang.sh
+++ b/hack/lib/golang.sh
@@ -222,9 +222,6 @@ kube::golang::set_platform_envs() {
   elif [[ ${platform} == "linux/arm64" ]]; then
     export CGO_ENABLED=1

-  elif [[ ${platform} == "linux/ppc64le" ]]; then
-    export CGO_ENABLED=1
-    export CC=ppc64le-redhat-linux-gcc
   fi
 }


Sorry for the inconvenient.

So what is the correct path that needs to be applied?

Created attachment 1150315 [details]
Use golang as compiler for ppc64le

The correct patch is this one.
