-5.  From here, you can follow https://github.com/openshift/origin/#start-developing[Start Developing] from the README.

+5.  From here, you can generate the OpenShift binaries by running:

+

+        $ make clean run

+

+6.  Next, assuming you have installed Docker 1.3.2 or higher, and that you have not changed the kubernetes/openshift service subnet configuration from the default value of 172.30.0.0/16, you need to instruct the Docker daemon to trust any Docker registry on the 172.30.0.0/16 subnet.  If you are running Docker as a service via `systemd`, add the `--insecure-registry 172.30.0.0/16` argument to the options value in `/etc/sysconfig/docker` and restart the Docker daemon.  Otherwise, add "--insecure-registry 172.30.0.0/16" to the Docker daemon invocation, eg:

+

+        $ docker -d --insecure-registry 172.30.0.0/16

+

+7.  Then, the OpenShift firewalld rules are also a work in progress. For now it is easiest to disable firewalld altogether:

+

+        $ sudo systemctl stop firewalld

+

+8.  Firewalld will start again on your next reboot, but you can manually restart it with this command when you are done running OpenShift:

+

+        $ sudo systemctl start firewalld

+

+9.  Now change into the directory with the OpenShift binaries, and start the OpenShift server:

+

+        $ cd _output/local/go/bin

+        $ sudo ./openshift start

+

+10.  Launch another terminal, change into the same directory you started OpenShift, and deploy the private docker registry within OpenShift with the following commands (note, the --credentials option allows secure communication between the internal OpenShift Docker registry and the OpenShift server, and the --config option provides your identity (in this case, cluster-admin) to the OpenShift server):

+

+        $ sudo chmod +r openshift.local.config/master/openshift-registry.kubeconfig

+        $ sudo chmod +r openshift.local.config/master/admin.kubeconfig

+        $ oadm registry --create --credentials=openshift.local.config/master/openshift-registry.kubeconfig --config=openshift.local.config/master/admin.kubeconfig

+

+11.  If it is not there already, add the current directory to the $PATH, so you can leverage the OpenShift commands elsewhere.

+

+12.  You are now ready to edit the OpenShift source, rebuild / restart OpenShift, and test your changes.

+

+13.  NOTE:  to properly stop OpenShift and clean up so you can restart OpenShift, execute:

+

+        $ sudo killall openshift

+        $ docker ps | awk 'index($NF,"k8s_")==1 { print $1 }' | xargs -l -r docker stop

+        $ mount | grep "openshift.local.volumes" | awk '{ print $3}' | xargs -l -r sudo umount

+        $ cd <to the dir you ran openshift start> ; sudo rm -rf openshift.local.*

 Hopefully the logs will provide some indication of what it failed (e.g. failure to find the source repository, an actual build issue, failure to push the resulting image to the docker registry, etc).

+One issue seen somewhat often is not being able to resolve any hostname (for example github.com) from within running containers.  If this shows up in your build logs, restart docker and then resubmit a build:
