Concourse

Project7.9K

Build declarative CI/CD and automation pipelines with a self-hosted, container-based system.

What you can build

  • Build a pipeline that takes a repository change as input, runs your test task, and reports a pass or failure for the change.
  • Build a release workflow that takes source code and a version identifier, runs your packaging task, and outputs a versioned release bundle.
  • Write a task that reads infrastructure configuration, checks it against your rules, and outputs a report of the violations to fix.
  • Build a task that takes a supplied sales CSV, normalizes its records and removes duplicates, then outputs a cleaned CSV for downstream use.
  • Build a task that combines a built artifact identifier with an environment-specific manifest and outputs a deployment bundle for review or use by a later step.

Try this prompt

Build a small end-to-end Concourse pipeline adaptation for testing changes in one Git repository. Provide the YAML pipeline and any task files needed: take a repository change as input, run a clearly documented test command in a task, and produce an unambiguous pass/failure result. Explain how the user supplies repository details and task dependencies, preserve source files, and describe how to load the pipeline using the official fly guidance. Do not assume a GUI or add undocumented Concourse features.

Get started

  1. Start a local instance

    For a local trial, follow the README Quick Start using its linked Docker Compose file. The documented setup brings up Concourse and a database; the page is available at localhost:8080.

  2. Get the CLI and connect

    Download fly from the local web UI's download-fly page, then follow the official Getting Started Tutorial to learn pipeline authoring and connect to the instance.

  3. Define a pipeline

    Write a declarative YAML pipeline. The README example uses a Git resource and a task; follow the documented fly set-pipeline guidance to load a pipeline into your instance.

License & notes

Apache-2.0Apache License 2.0 permits commercial use. When redistributing, retain required license and attribution notices and mark modified files. Concourse itself does not establish your hosting or compute costs: budget for the infrastructure and worker capacity you provide. The supplied evidence documents no required paid API or model.

  • Pipeline configuration is YAML rather than GUI-based; the user must author and maintain the pipeline and task definitions.
  • A usable instance needs hosting and compute infrastructure supplied by the operator; the supplied README does not specify its cost or capacity needs.
  • Apache-2.0 permits commercial use; redistribution requires applicable license and attribution notices, and distributed modified files must be marked.
