Building a Dockerized Test Environment

The install tax kills Test Infrastructure

If every engineer spends a day installing databases before the first automated run, Test Infrastructure has already failed. Docker Testing exists to remove that tax.

I publish pull-and-run images so local laptops and CI share the same environment contract.

Principles that keep images usable

• Predictable tags over clever names
• One service per image when possible
• Docs written for pull-and-run, not folklore
• Live pull metrics so adoption is visible
