The main goal: \n\n_Make it possible to review a complex changeset and reason about the potential impacts of executing it._\n\n## Building\n\n```sh\ngo build\n```\n\n## Using\n\n```sh\n$ id=$(aws cloudformation create-change-set ... --output text --query Id)\n$ ./explain-cloudformation-changeset --change-set-name=${id} --graph-output=graph.svg\n```\n\nThe tool will download (nested) changeset descriptions and save them by default in the current working directory as JSON files. This can be changed by using the `--cache-dir` argument. If a changeset specified on the command-line already is cached, the cached version will be used. \n\nThe [examples](./aws-examples) can be used by setting the cache directory accordingly:\n\n```sh\n./explain-cloudformation-changeset --cache-dir=aws-examples --change-set-name=SampleChangeSet-direct --graph-output=SampleChangeSet-direct.svg\n```\n\n## TODO \u0026 Ideas\n\n* Table: Build a simple CSV with all planned changes\n* Augment information from changeset with information from template(s) (should point to S3 location of packaged template, so we can find nested stack templates automatically)\n\n## License\n\nSee [LICENSE](./LICENSE) for the license of the code.\n\nThe files in [aws-examples](./aws-examples) have been taken from \u003chttps://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets-samples.html\u003e and are licensed under a [modified MIT license](https://github.com/awsdocs/aws-cloudformation-user-guide/blob/main/LICENSE-SAMPLECODE).\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fankon%2Fexplain-cloudformation-changeset","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fankon%2Fexplain-cloudformation-changeset","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fankon%2Fexplain-cloudformation-changeset/lists"}
