containerizing apache
with docker

Continuous validation with UpGuard scans and policies ensured that engineers could quickly trace mistakes and regenerate Dockerfiles with a push of a button.

A US-based financial services provider wanted to containerize their Apache instances with Docker. Building Apache from source each month had introduced unexpected libraries, so they had previously implemented UpGuard to monitor for package changes. Docker offered a way to insulate an app's resources from the OS and further reduce drift.

Getting Visibility

Using UpGuard had given them the information to clean up existing configuration drift. Working from a clean, drift-free environment they were in a position to move ahead with more ambitious measures. Docker addressed another point in the pipeline that could reduce the number of downstream conflicts.

UpGuard Policies Export as Dockerfiles

As an existing UpGuard user, the company had already defined policies that tested critical configuration items. In UpGuard, policies can be executed as tests or exported as resource files for a number of tools — including Docker. The mapping between Docker containers and UpGuard policies made the process incredibly easy: the configuration items that needed frequent testing were the same ones that differentiate a container from the shared OS.

Executable Documentation

Despite minimal experience working with Docker, the assistance that UpGuard gave the team, in both documentation of the existing state and the creation of the Dockerfiles, allowed them to complete their project well ahead of schedule. Read the case study to learn more about the challenges they faced and the total return on investment.
