There was a problem hiding this comment. I didn't know there is such a helper. |

| // TODO: Implement planpreview builder. | ||
| // 1. Fetch the source code at the head commit. | ||
| // 2. Determine the list of applications that will be triggered. | ||
| // - Based on the changed files between 2 commits: head commit and mostRecentlyTriggeredCommit | ||
| // 3. For each application: | ||
| // 3.1. Start a builder to check what/why strategy will be used | ||
| // 3.2. Check what resources should be added, deleted and modified | ||
| // - Terraform app: used terraform plan command | ||
| // - Kubernetes app: calculate the diff of resources at head commit and mostRecentlySuccessfulCommit | ||
| return nil, fmt.Errorf("Not Implemented") | ||
