Installing Openshift Origin on your CentOS 7 VM

sudo yum install centos-release-openshift-origin

sudo yum install wget git net-tools bind-utils iptables-services bridge-utils bash-completion origin-clients

sudo oc cluster up

at this point, you get a terrifying

-- Checking Docker daemon configuration ... FAIL
   Error: did not detect an --insecure-registry argument on the Docker daemon
   Solution:

     Ensure that the Docker daemon is running with the following argument:
      --insecure-registry 172.30.0.0/16

after some googling, I start with :

sudo oc cluster up --skip-registry-check=true

Starting OpenShift using openshift/origin:v3.6.0 ...
OpenShift server started.

The server is accessible via web console at:
    https://127.0.0.1:8443

You are logged in as:
    User:     developer
    Password: 

To login as administrator:
    oc login -u system:admin

I open the console at https://127.0.0.1:8443 (add security exception) and login with system/admin

go to overview

If you see an error in the logs "Could not resolve host: github.com", you are screwed !
Haha no, just "sudo systemctl restart docker" , then "oc start-build --from-build=yourbuildid"




create a new project, java, wildfly, copy git url, create project pvproject01

oc login https://127.0.0.1:8443

system/admin

oc project pvproject01

oc status




If you get this

[centos@localhost ~]$ oc cluster up --skip-registry-check=true 
-- Checking OpenShift client ... OK
-- Checking Docker client ... OK
-- Checking Docker version ... FAIL
   Error: Minor number must not contain leading zeroes "09"

it simply means that OpenShift developers are morons, and you have to wait the next release 1.5 for a fix. What a pathetic mess.



I have also followed these instructions https://fedoramagazine.org/experimenting-docker-openshift/ and they seem to work:

(at the beginning I am troubleshooting VirtualBox guest additions, which is also a good thing to record)
