octocatalog-diff is a tool to detect and display differences in Puppet catalogs compiled from different
environments. The catalogs may be obtained through any of the following means:
• Compilation using a local puppet instance
• Puppet master 3.x/4.x HTTP API
• PuppetDB HTTP API
• Precompiled JSON catalogs
octocatalog-diff filters out attributes or resources with no effect (e.g. tags) and displays only state
differences between the two catalogs. It does not require a working Puppet master (or puppetserver),
making it suitable for development use and use in Continuous Integration environments.
