Harness, Thursday, October 8th, 2026
Harness walks through generating a CI pipeline from a GitHub repo and pushing a Docker image without writing YAML.
A Harness tutorial shows how to connect a GitHub repository and have Harness CI auto-generate a pipeline without writing YAML.
Using a Java Maven project with 42 unit tests and a Dockerfile, Harness detected the stack and generated build, test and cache steps, and the author added a push step to DockerHub.
The full build, test and push pipeline ran in just over three minutes, and the post cites a 2025 Stack Overflow survey finding that 84% of developers use AI tools, increasing pressure on CI.
