When developing software it makes sense to be able to work on local files, while the source code should be served from a controlled environment (a container) to prevent pollution of the developer workstation.
In this article I will describe the evolution of a development workflow for deploying applications on OpenShift. The ultimate goal is to make it possible to maximize dev/prod parity, while minimizing the idle time in the change/test cycle.
... [continue reading]The 12-factor app presents a number of guidelines to achieve DevOps compliancy. One of the guidelines specifies dev/prod parity, which in OpenShift can be implemented by re-using a single container image for all steps within an applications life cycle. Here we will describe how dev/prod parity can be achieved within OpenShift by using the pipeline support of the OpenShift BuildConfig object ... [continue reading]

As mentioned in the previous Ansible post, we use Ansible quite a lot for day to day operations. While we prefer Puppet for configuration management, Ansible is excellent for automation of maintenance procedures.
One such procedure is gracefully applying package upgrades, including any required reboot, of application servers. In this post we’ll take a look at upgrading a cluster of web application servers defined in the Ansible hostgroup “webservers”. They’re located behind a redundant pair of HAProxy load balancers ...
