kubeformat

Tool to remove junk from kubectl manifests. For those of you who are also tired of kubectl flooding you with useless information. Also my coursework.

Installation

wget link_to_latest_release -O kubeformat
chmod +x kubeformat
mv kubeformat ~/usr/local/bin/kubeformat

Features:

• Cleans up fields using filters defined in cmd/defaults.go or in -p filename. Sample JSON with filters can be found in sample/. Usage: ... | kubeformat -p filepath. Note that wildcard (*) only works for containers, and you should escape irrelevant dots with \\
• Iterates over containers(container filters are defined with *, "spec.template.spec.containers.*.terminationMessagePath")
• Removes empty fields
• Flattens Lists

Example

TODO

• Improve and unify error handling, right now its a mess
• Add tests
• Refactor function and variable names to be in line with conventions
• Maybe add statefulness (path to filters)
• Add parsing of multiple manifests (--- case)
• Maybe add optional secret decoding from b64
• Output in JSON
• Cleanup out-of-the-box CLI flags
• Read input from files cat file | kubeformat accomplishes the same
• Add installation guide
• Importing custom filters

Usage

kubectl -n default get deployment | kubeformat
