I updated older posts with newer tech (August 2016)

I’ve taken some time today to update my system operations related posts with newer information. This information is based on the usage and issues that we faced and will hopefully prevent others from stumbling into the same problems should they choose to follow my guidance.

• Using Continuous Integration for puppet was updated with sections about prebuilding your Docker image to speedup a build process as well as some advice for continuous deployment and an improved Makefile.
• Improving our Xen Usage was updated with sections about DRBD 9 auto promotion of resources and the “folder per hostname” approach we use in production.
• Building and Deploying a C++ library with GitLab was updated with a section concerning use of the expire_in parameter for GitLab CI jobs.
