KubeGlass 🔮
Overview
Make kubernetes API changes between versions as transparent as glass.
NOTE: This program only works with kubernetes versions 1.28+.
Description
KubeGlass allows to compare 2 kubernetes versions and see what changed on the different APIs between them.
Installation
Run go install github.com/clebs/kubeglass
.
Usage
Online
To compare 2 kubernetes versions run kubeglass --from=1.28 --to=1.29
. This will show the following output:
This usage requires internet connection as it downloads all necessary information to compare APIs based on the given versions.
Offline
For those cases where an internet connection is not available, the aggregated discovery API files can be downloaded from the Kubernetes GitHub (e.g. here).
Then running kubeglass as follows:
kubeglass --from=./relative/path/to/file/aggregated-api-1.28.json --to=/absolute/path/to/file/aggregated-api-1.29.json
Roadmap
- Persistent caching of downloaded data
- Airgapped support
- Allow
-f/--from
and -t/--to
flags to take input files.
- Richtext and colored printing to stdout
- Krew support
- Scan running clusters via the
/apis
endpoint
