Docker Playwright Configuration FAQs

Question 1

Can I use this for API testing as well as UI testing?

Accepted Answer

Yes, the skill includes logic to map and test both UI containers (usually via port 80) and API containers (usually via health check endpoints).

Question 2

Does this skill support Docker Compose?

Accepted Answer

Yes, it is designed to work seamlessly with Docker Compose environments by mapping individual service names to their respective network IP addresses.

Question 3

Why should I use container IPs instead of localhost for Playwright?

Accepted Answer

Localhost often refers to the host machine or the Playwright runner itself, which leads to connection failures when the target application is isolated inside a Docker network. Using container IPs ensures direct, reliable access.

Question 4

Is this skill compatible with CI/CD runners?

Accepted Answer

Absolutely. The included scripts are designed to be used in shell environments like GitHub Actions or GitLab CI to prepare the environment before triggering Playwright tests.

Question 5

How does this skill handle containers that change IPs after a restart?

Accepted Answer

The skill provides a dynamic retrieval workflow that fetches the latest container IPs immediately before a test run, eliminating the risks associated with hardcoded IP addresses.
