Deploy a Preview Environment (AKA "Ephemeral Environment") for every pull request. Supports APIs, frontends, backends, databases, microservices, binaries and command-line tools.
Uffizzi integrates as a step in your GitHub Actions pipeline to manage on-demand, ephemeral test environments for every feature branch/pull request. Preview Environments are deployed on Uffizzi Cloud (SaaS) or your own installation of open-source Uffizzi (self-hosting requires Kubernetes).
We've published a Reusable Workflow for your GitHub Actions. This can handle creating, updating, and deleting Uffizzi Preview Environments. It will also publish Preview Environment URLs as a comment to your pull request issues.
💡 We recommend using this reusable workflow instead of using the individual actions for create, update, and delete.

This example builds and publishes an image to Docker Hub for pull request events. It then renders a Docker Compose file from a template and caches it. Finally, it calls the reusable workflow to create, update, or delete the Preview Environment associated with the pull request.

Note that if this is an emtpy string, the reusable workflow will delete the preview associated with this Pull Request.
(Required) Path of hashed compose file, using GitHub's cache action
(Required) https://app.uffizzi.com/ or the URL of your Uffizzi installation
(Optional) If you're calling this workflow from a workflow that's not triggered by pull_request, you may want to specify the PR number here.
(Optional) If you're calling this workflow from a workflow that's not triggered by pull_request, you may want to specify the branch or other git reference here.
(Optional) If you're controlling access to the URLs of your Preview Environments, set the credentials here so the workflow can confirm successful deployment.
URL path that will be appended to the preview URL where the reusable workflow will check for the health of the preview. URL path has to start with /. Use this if the root URL of your application does not return an HTTP response code below 400.
If specified, this text string will be added to each comment this workflow makes on the pull request issue. The default is a link to learn more about Uffizzi.
If you're using the reusable workflow with Uffizzi Cloud, an account and project will be created from your GitHub user and repository information when the workflow runs. If you're self-hosting open-source Uffizzi, you will need to create a Uffizzi user and project before running the workflow, then set username, password, and project inputs, where project is the Uffizzi project slug.
