OpenShift#
After a failed attempt to run a local cloudfoundry instance with bosh-lite
, because my laptop only has 4 GB memory, I started to check out running OpenShift on my own box.
This can be done by running OpenShift origin as a VirtualBox guest.
I also want to try and get the WebSphere Liberty Profile cartridge working.
Resources#
- OpenShift docu index
- OpenShift Origin User’s Guide
- OpenShift Origin Virtual Machine Deployment Guide
- WebSphere Liberty Profile cartridge
- OpenShift Console
Install VirtualBox and setup the openshift VM.#
First install VirtualBox and then install the prebuilt openshift origin as described in the OpenShift Origin Virtual Machine Deployment Guide. Make sure to set the first network interface to bridging (instead of adding a second interface as described in the doc).
The web console is available at https://10.0.0.171/console, there you can upload your public SSH key, which you need when git-cloning your app.
Set up client tools#
The next thing is installing the client tool , rhc. This can be done with gem install rhc. You do have to setup ruby: sudo apt-get install ruby ruby-gems.
Run rhc setup, this will create ~/.openshift/express.conf
For the OpenShift origin install a user demo with password changeme was created, so will use that one :
Connection to aap-origin.openshift.local closed. metskem@athena:~/cloud/openshift/apps/aap$ rhc setup 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. If you have your own OpenShift server, you can specify it now. Just hit enter to use the server for OpenShift Online: openshift.redhat.com. Enter the server hostname: |openshift.redhat.com| 10.0.0.171 You can add more servers later using 'rhc server'. The server's certificate is self-signed, which means that a secure connection can't be established to '10.0.0.171'. 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 10.0.0.171: 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) yes Generating an authorization token for this client ... lasts about 1 day Saving configuration to /home/metskem/.openshift/express.conf ... done Checking for git ... found git version 1.9.1 Checking common problems .. done Checking for a domain ... origin Checking for applications ... found 1 aap http://aap-origin.openshift.local/ You are using 1 of 100 total gears The following gear sizes are available to you: small Your client tools are now configured. metskem@athena:~/cloud/openshift/apps/aap$
You can also upload your public SSH key via the webconsole, this SSH key is necessary when you git-checkout your application.
Install the Liberty cartridge#
The WebSphere Liberty Cartridge, available at https://github.com/WASdev/cloud.openshift.cartridge.wlp can be installed via the web-console by entering the URL to the manifest file.
This install will fail because the Source-Url element is required. I forked the github project and change the manifest file to include the Source-Url
During this install you also have to create an application, so I created an application called "aap", which is then accessible at http://aap-origin.openshift.local/ , but this gives a 503 error. No idea why.
So further debugging, you can login to the node with the applications generated account and ssh keys :
metskem@athena:~/cloud/openshift/apps/aap$ ssh 54908968653e8a8670000013@aap-origin.openshift.local

And then we find the cause :
[aap-origin.openshift.local 54908968653e8a8670000013]\> gear restart Cart to restart? 1. liberty-8.5.5 ? 1 app is not running missing Liberty license, set IBM_LIBERTY_LICENSE env var [aap-origin.openshift.local 54908968653e8a8670000013]\>
The Liberty Profile License code is L-EWOD-99YA4J which can be found here
Setting environment variables #
To use the Liberty Profile, you have to set an envvar, this can be done with the rhc only:
metskem@athena:~/cloud/openshift/apps/aap$ rhc set-env IBM_LIBERTY_LICENSE=L-EWOD-99YA4J --app aap Setting environment variable(s) ... done
TODO#
- find out how to set envvars (for the IBM_LIBERTY_LICENSE = L-EWOD-99YA4J} , must be done with client tool , webUI does not offer this option...
