Fedora 19 is when OpenShift Origin first became a feature.
 
Fedora 19 is when OpenShift Origin first became a feature.
 +

NOTE: (August 8, 2013) This page is getting an update.  It will accommodate F19 cloud images (not just minimal install).  It is also updated with the OpenShift Origin Version 2 documentation.
  
 
This page is here to show how to setup OpenShift Origin on Fedora 19 using the packages in Fedora, as opposed to the packages published from upstream.  These steps are written out to be done by hand.  Yes, people can script and/or puppetize these steps.  But these are written out so that people can see, and fine tune them.

Note: And now they have been written into scripts. https://github.com/tdawson/oo-install-scripts
  
 
Goal: By the end of this, you should have two machines.  A broker machine, and one node machine.  You should be able to create applications, that will be put on the node machine.  You should be able to check the status of those applications.  You should be able to point your web browser to the URL of those applications.

Latest revision as of 13:39, 8 August 2013

Fedora 19 is when OpenShift Origin first became a feature.

NOTE: (August 8, 2013) This page is getting an update. It will accommodate F19 cloud images (not just minimal install). It is also updated with the OpenShift Origin Version 2 documentation.

This page is here to show how to setup OpenShift Origin on Fedora 19 using the packages in Fedora, as opposed to the packages published from upstream. These steps are written out to be done by hand. Yes, people can script and/or puppetize these steps. But these are written out so that people can see, and fine tune them.

Note: And now they have been written into scripts. https://github.com/tdawson/oo-install-scripts

Goal: By the end of this, you should have two machines. A broker machine, and one node machine. You should be able to create applications, that will be put on the node machine. You should be able to check the status of those applications. You should be able to point your web browser to the URL of those applications.

Note: There is no web console in Fedora 19. That will be in Fedora 20.

These instructions were created most from the following two places.

cd -

setup permissions for the DNSSEC key pair

restorecon -v /etc/rndc.* /etc/named.*
chown -v root:named /etc/rndc.key
chmod -v 640 /etc/rndc.key

setup forwarders

Check and Setup User

yum -y install rubygem-rhc

Should look like (Note: Generate a token now? no - client can handle it, broker in F19 cannot)

OpenShift Client Tools (RHC) Setup Wizard

This wizard will help you upload your SSH keys, set your application namespace, and
check that other programs like Git are properly installed.

The server's certificate is self-signed, which means that a secure connection can't be
established to 'broker.example.com'.

You may bypass this check, but any data you send to the server could be intercepted by
others.

Connect without checking the certificate? (yes|no): yes
Login to broker.example.com: demo
Password: ****
 
OpenShift can create and store a token on disk which allows to you to access the
server without using your password. The key is stored in your home directory and
should be kept secret.  You can delete the key at any time by running 'rhc logout'.
Generate a token now? (yes|no) no

Saving configuration to /root/.openshift/express.conf ... done

No SSH keys were found. We will generate a pair of keys for you.

    Created: /root/.ssh/id_rsa.pub

Your public SSH key must be uploaded to the OpenShift server to access code.  Upload
now? (yes|no)
yes

Since you do not have any keys associated with your OpenShift account, your new key
will be uploaded as the 'default' key.

Uploading key 'default' ... done

Checking for git ... found git version 1.8.2.1

Checking common problems .. done

Checking your namespace ... none

Your namespace is unique to your account and is the suffix of the public URLs we
assign to your applications. You may configure your namespace here or leave it blank
and use 'rhc create-domain' to create a namespace later.  You will not be able to
create applications without first creating a namespace.

Please enter a namespace (letters and numbers only) |<none>|: demoland
