Install OKD 3.11 with source version of openshift-ansible installer

To install OpenShift by openshift-ansible from sources, one needs to build the openshift-ansible RPMs and install them as a repo on the machine performing the installation. For 3.11 in CI this is done by the following YAML.

First clone openshift-ansible repo.

$ git clone --depth=1 --branch=release-3.11

Then build base image as described in the YAML.

$ cd openshift-ansible
$ BUILDAH_LAYERS=false sudo podman build -f images/installer/Dockerfile -t ocp-ansible --layers=false .

Run the image and prepare for RPM building

$ sudo podman run -t -a STDIN -a STDOUT -a STDERR --rm=true -u root ocp-ansible /bin/bash
# yum install tito createrepo
# git clone --depth=1 --branch=release-3.11
# git config --add
# git config --add myname

Build RPMs as pointed in the rpm building section of the YAML with slight modifications. In bold I write things that differ.

# tito tag --offline --no-auto-changelog
# tito build --output="_output/local/releases" --rpm --test --offline --quiet
# createrepo _output/local/releases/noarch

Now RPM repo is under `_output/local/releases/noarch/`.  Copy it to a web server or locally on the machine where you would run the installation. Then create a file /etc/yum.repos.d/my-ocp-ansible.conf:

baseurl = <file:// or http:// url of RPM repo>
enabled = 1
gpgcheck = 0
name = Custom built OpenShift Ansible repo

Finally perform the installation as described in the official docs.

$ ansible-playbook ....

Make sure that you see your RPMs in the install log under `List all openshift ansible packages`.

Building debug firefox build from source RPM on Red Hat Enterprise Linux

In short:
  • Create an account on
  • Get Red Hat Enterprise Linux (RHEL)
    • Download and install RHEL server on a local physical or virtual machine (it is free with developer subscription).
    • Or spawn a RHEL machine in some cloud service.
    • Important:  you will need a large machine. For me 4GB failed [*] and I used a 16GB one. I didn't check what is the minimum required.
  • If you installed your own RHEL, then you need to subscribe the machine.
    • subscription-manager register # use your credentials
    • subscription-manager attach
      • if the above does not work automatically try the below
      • subscription-manager list --available
      • subscription-manager attach --pool=<whatever you find useful above>
  • sudo yum install yum-utils rpm-build
  • yumdownloader --source firefox
  • rpm -ivh firefox-*.rpm
  • sudo yum-builddep rpmbuild/SPECS/firefox.spec
    • on a vanilla system you will see missing dependencies
    • if you wanted to figure that out by yourself, you'd go to and search for the packages to see what repos they come from (or maybe use some clever yum command that I don't know atm)
  • yum-config-manager --enable rhel-7-server-devtools-rpms rhel-7-server-optional-rpms
    • or edit /etc/yum.repos.d/redhat.repo
  • sudo yum-builddep rpmbuild/SPECS/firefox.spec # this time it will succeed
  • rpmbuild -ba --with=debug_build rpmbuild/SPECS/firefox.spec
  • find the built rpm at
    • ~/rpmbuild/RPMS/x86_64/firefox-60.4.0-1.el7.x86_64.rpm
    • ~/rpmbuild/RPMS/x86_64/firefox-debuginfo-60.4.0-1.el7.x86_64.rpm
    • ~/rpmbuild/SRPMS/firefox-60.4.0-1.el7.src.rpm

[*] it is really sad, in the past one could learn to be a developer on a budget machine. Nowadays it seems like even compiling your code takes a beefy one :/
