Frizbee is a tool you may throw a tag at and it comes back with a checksum.

It's a command-line tool designed to provide checksums for GitHub Actions and container images based on tags.

It also includes a set of libraries for working with tags and checksums.

To install Frizbee, you can use the following methods:

# Using Go

go install github.com/stacklok/frizbee

# Using Homebrew
brew install stacklok/tap/frizbee

# Using winget
winget install stacklok.frizbee

Frizbee can be used to generate checksums for GitHub Actions. This is useful for verifying that the contents of a GitHub Action have not changed.

To quickly replace the GitHub Action references for your project, you can use the ghactions command:

frizbee ghactions -d path/to/your/repo/.github/workflows/

This will write all the replacements to the files in the directory provided.

Note that this command will only replace the uses field of the GitHub Action references.

Note that this command supports dry-run mode, which will print the replacements to stdout instead of writing them to the files.

It also supports exiting with a non-zero exit code if any replacements are found. This is handy for CI/CD pipelines.

If you want to generate the replacement for a single GitHub Action, you can use the ghactions one command:

frizbee ghactions one metal-toolbox/container-push/.github/workflows/container-push.yml@main

This is useful if you're developing and want to quickly test the replacement.

Frizbee can be used to generate checksums for container images. This is useful for verifying that the contents of a container image have not changed.

To get the digest for a single image tag, you can use the containerimage one command:

frizbee containerimage one quay.io/stacklok/frizbee:latest

This will print the image refrence with the digest for the image tag provided.
